Firefox Browser is a free and open-source web browser developed for Windows, OS X, and Linux, with a mobile version for Android, by the Mozilla Corporation. Firefox uses the Gecko layout engine to render web pages, which implements current web standards.
The Mozilla project was created in 1998 with the release of the Netscape browser suite source code that was intended to harness the creative power of thousands of programmers on the Internet. The Firefox project began as an experimental branch of the Mozilla project. Mozilla 1.0, the first major version, was released in 2002. This version featured many improvements to the browser, email client and other applications included in the suite, but not many people were using it. By 2002, well over 90% of Internet users were browsing with Internet Explorer. Not many people noticed at the time, but the first version of Phoenix (later renamed to Firefox) was also released by Mozilla community members that year with the goal of providing the best possible browsing experience to the widest possible set of people. In 2003, the Mozilla project created the Mozilla Foundation, an independent non-profit organization supported by individual donors and a variety of companies. The new Mozilla Foundation continued the role of managing the daily operations of the project. Firefox 1.0 was released on November 9, 2004.
Firefox Features List from Mozilla
Get to your favorite sites quickly – even if you don’t remember the URLs. Type your term into the location bar (aka the Awesome Bar) and the autocomplete function will include possible matches from your browsing history, bookmarked sites and open tabs.
Tabs on Top:Tabs are above the Awesome Bar to make it easier to focus on the content of the sites you visit.
Firefox Button:All your menu items are now found in a single button for easy access.
Bookmark Button: Manage your bookmarks in a single button. Find your favorite links without getting bogged down!
Simplified Reload/Stop Button: Your Awesome Bar now features one easy button to stop loading pages or reload pages.
Home Button: The Home button has been moved to the right side of the search-field.
Pinned Tabs: Take sites you always keep open—like Web mail—off your tab bar and give them a permanent home in your browser.
Switch-to-Tab: As you’re opening a new tab or typing in the Awesome Bar, Firefox will check to see if you already have that site open. If you do, you’ll be directed to the existing tab so you don’t open a duplicate.
New Tab: Firefox helps you get to your next task faster than ever by displaying a set of thumbnails of your most recently and frequently visited sites every time you open a new tab. You can also customize this page by adding, removing or reorganizing sites to get to where you want to go in one click.
Reopen Closed Tabs and Windows: If you accidentally close a tab or window, you can reopen it in one click. Just view Recently Closed Tabs or Recently Closed Windows in the History menu and select the tab or window you’d like to reopen.
Smooth Scrolling: Like to have all 20 of your favorite pages open at once? An elegant new feature lets you scroll through tabs easily to see them all and access the one you want quickly.
Stay in Sync
Sync seamlessly connects your desktop and mobile Firefoxes, so you can access your browsing history, passwords, bookmarks and even open tabs no matter which device you use. Access years of desktop browsing the first day you fire up your mobile, and use saved passwords from your desktop to fill out forms on your phone.
Tired of trying to remember or retype your passwords every time you visit a favorite site? Firefox is here to help! You’ll be prompted with a non-intrusive option to remember passwords when you first log in—after that, Firefox will take care of the rest.
When you’re filling out an online form like your shipping address, Firefox will suggest information for each field based on your most common answers for similar fields in other forms. Tired of typing out the same answers over and over? You’ll be zipping through the forms in no time!
Banish pop-ups (and pop-under windows) from your surfing experience once and for all. Or, find a happy medium: choose to view blocked pop-ups or create an “allow” list of sites whose pop-ups you’re okay with seeing.
Integrated Web Search: Searching the Web is a breeze with the search box, located just to the right of your location bar. Select the service of your choice and enter your search terms into the box. The box width is even adjustable if you need more space.
Search Suggestions: Start typing in the search bar and it will prompt you with a drop down of filled-in suggestions. You can even use the search bar as a calculator, converter and more.
Hundreds of Search Engines: Choose from the preset dropdown list of search options or select “manage search engines” to browse for many more search-related add-ons.
Smart Keywords: Search the Web in record time with smart keywords. With a few clicks you can assign keywords to search engines, and then simply enter your key and search words in the location bar. Assigning “books” to Amazon.com means you can type in a search like “books about home building” and zip right there, with no pausing on the Amazon home page.
Location-Aware Browsing: Need directions, or help finding a restaurant? Firefox can tell sites where you’re located so you can get the most relevant and useful information. The browser won’t share your location without your permission, either – your privacy is the top priority.
Session Restore instantly brings back your windows and tabs, restoring text you entered and any in-progress downloads. You can restart the browser without losing your place after you install an add-on or software update. And, if Firefox or your computer unexpectedly closes, you don’t have to spend time recovering data or retracing your steps through the Web. If you’re in the middle of typing an email, you’ll pick up where you left off, even down to the last word you typed.
A built-in spell checker works directly in Web pages, like blog posts and email. Save yourself a step and stop worrying about typos.
One-Click Bookmarking: Manage your bookmarks a lot or a little. One click on the star icon at the end of the location bar bookmarks a site. Two clicks and you can choose where to save it and whether to tag it. File bookmarked sites in easy-to-access folders and organize according to theme (like “job search” or “favorite shopping”). Find your bookmarked sites in a flash by entering the tag, page or bookmark name into the location bar. The more you use your tags and bookmark names in the location bar, the more the system will adapt to your preferences
Tags: Label a site with names or categories that are meaningful to you. For example, you can label both www.bbc.co.uk and www.nytimes.com with the “news” tag. When you enter “news” into the location bar, both sites will be shown as results. A single site can have multiple tags, and there’s no limit to the number of tags you can create. You may not remember the exact name of a site, but with a tag, you’ll be able to find it easily.
Search and Find
The find feature appears with a simple keystroke. Search for a word or phrase on an open Web page. Highlight text before using the feature and the finder opens pre-filled with your selection. See all instances of your search at once, or scroll backwards and forwards through any appearances of the word on the page.
Download files seamlessly and securely! A pause and resume feature means you can stop and start anytime. So, if you’re halfway through downloading a big file and it’s time to catch the bus, just pause and pick up where you left off later. The resume function also works if your system crashes or is forced to restart. The manager shows your download progress and even lets you search your files by name or the Web address where the download came from.
Naturalized Look & Feel
The Firefox platform looks and feels like home. Think of it as a Firefox who’s really good at making friends. Whether you use Windows 7, Mac or Linux, the browser seamlessly integrates into your computer’s environment. A native look makes for a flawless interface that never gives you pause.
RSS Feed Reader
Spending hours combing the Web for the latest news and updates? Instead, add an RSS feed icon to your toolbar and create feeds using an online web service, a client-side feed reader or by creating a Firefox Live Bookmark.
Take your computer offline and still have your information at your fingertips. Certain sites may allow applications—like your Web-based email—to stay with you at all times.
Want to see captions and pictures in a larger size? An elegant new zoom feature lets you swoop in and see the details on web pages, zeroing in on what matters. The pages will scale equally, with all the elements of layout changing at the same level.
Experience super-fast graphics acceleration of video and Web content with a new layers-based graphics system that takes advantage of Direct2D and Direct3D on Windows.
Real World Performance
3D on the Web
WebGL brings 3D graphics to Firefox, opening the door for developers to create vivid games and new kinds of visualizations and experiences on the Web.
Firefox provides uninterrupted browsing when there is a crash in the plugins for Adobe Flash, Apple QuickTime or Microsoft Silverlight. If one of these commonly-used plugins crashes or freezes, it won’t affect the rest of the browser. You can simply reload the page to restart the plugin and try again.
Instant Web Site ID
Want to be extra sure about a site’s legitimacy before you make a purchase? Click on its favicon for an instant identity overview. Another click digs deeper: how many times have you visited? Are your passwords saved? Check up on suspicious sites, avoid Web forgeries and make sure a site is what it claims to be.
Sometimes it’s nice to go undercover: Open a private window and protect your browsing history. You can switch between private and normal windows quickly, so it’s easy to go back to what you were doing before. This feature is great if you’re doing your online banking on a shared computer or checking email from an Internet café.
Do Not Track
Many sites track your online behavior and sell that data to advertisers. If that makes you uncomfortable, Firefox lets you tell sites you want to opt out of behavioral tracking and keep your browsing habits private.
Forget This Site
Having second thoughts about having visited a certain site? Remove every trace of ever having been there!
Content Security Policy
The Content Security Policy in Firefox is designed to shut down cross-site scripting attacks by providing a mechanism for sites to explicitly tell the browser which content is legitimate. The browser can then disregard any content that has not been blessed by the site, keeping you protected in the process.
Securing Website Connections
Firefox keeps attackers from intercepting your sensitive data by automatically establishing secure connections to websites that offer secure https servers.
Firefox integrates elegantly with your Windows anti-virus software. When you download a file, your computer’s anti-virus program automatically checks it to protect you against viruses and other malware, which could otherwise attack your computer.
Shop and do business safely on the Internet. Firefox gets a fresh update of forgery sites a whopping 48 times a day, so if you try to visit a fraudulent site that’s pretending to be someone you trust (like your bank), a warning message will stop you before any harm is done.
Firefox updates itself automatically so you can rest assured that your browser is always up to date with the latest and greatest security fixes. And the best part is, you don’t have to do a thing.
Customized Security Settings
Control the level of scrutiny you’d like Firefox to give a site. You can even enter exceptions—sites that don’t need the third degree. Customize settings for passwords, cookies, loading images, and installing add-ons for a fully empowered Web experience.
Clear Recent History
Clear all your private data or just your activity over the past few hours with a few quick clicks. You have full control over what to delete, and then your info is gone for good—on your own computer or the one at your local library. It’s that easy.
Outdated Plugin Detection
Plugins are small bits of third-party software built by companies like Adobe Systems or Apple to power videos, animation and games. They can be major security risks when they get out of date, so Mozilla built an easy tool to help you stay current.
Enforce parental control settings you’ve entered on Windows 7 to stop unwanted downloads and more.
Firefox looks for a secure connection before installing or updating add-ons, third-party software, and themes.
Firefox protects you from viruses, worms, trojan horses, and spyware delivered over the Web. If you accidentally access an attack site, it will warn you away from the site and tell you why it isn’t safe to use.
The Add-ons Manager has been redesigned to let you discover and install add-ons without ever leaving Firefox. Browse ratings, recommendations, descriptions and pictures of the add-ons in action to help you make your selection. Your Add-ons Manager even lets you view, manage and disable third-party plugins in a few easy clicks, checking and auto-updating any of your installed add-ons every time you open the Manager pane.
Dress Up Your Firefox with Themes
Change the look of your Firefox to practically anything with Themes: thousands of easy-to-install themes created by users from around the world (or that you make yourself!). With a single click, you can dress your browser up in simple designs, colorful patterns, and content from partners like Harry Potter and Bob Marley.
Everyone likes to browse their own way, so we’ve made it easy to adjust the Firefox interface to be exactly the way you like it: re-arrange, organize, add or remove buttons or fields to change your browsing experience however you want. Just right click on the navigation toolbar and select the Customize option to get started.
Add-ons are the cornerstone of customization, but adapting Firefox to suit your style doesn’t stop there. You can add new search engines, change toolbar preferences, display different sizes, shapes and styles for your browser’s navigation buttons and more. With additional preferences, you can specify a Web mail client (such as Gmail) to open up when you click on an address from a Web page or set up a news reader application for the blogs you encounter.
100,000s of Ways to Customize
The sky’s the limit with a growing library of thousands of Firefox add-ons, little extras you choose to download and install for a browser that works your way. Manage online auctions, upload digital photos, see the weather forecast in a glance and listen to music all from the convenience of your browser.
Newest Web Technologies
Site authors and developers will love Firefox’s new and enhanced functionalities. If creating advanced content and applications gets you excited, Firefox is the best browser choice.
Firefox includes an HTML5-ready parser. This parser brings with it some new capabilities, most notably inline SVG, but also improves performance by running the parsing algorithm on its own processor.
Enhanced File API
With added support for .click() to the File upload control, .slice and file API urls, Firefox allows developers to better customize the file upload experience.
Stylin’ Pages with CSS3
Support for new CSS3 features like border-radius, box-shadow and other Transitions, Animations and Transformations makes it easy to add elegant animations to Web pages.
SPDY is a protocol designed as a follow-up to HTTP that reduces the amount of time it takes for websites to load. You’ll especially notice faster page load speeds on sites that support SPDY networking. SPDY also encrypts all communication with SSL, which helps make browsing with Firefox even more secure.
WebSockets open the door to instantaneous two-way communications between Firefox and Web servers. This makes it easier for developers to build real-time messaging applications and HTML5 games on the Web that are more responsive and interactive than ever before.
Firefox includes an early version ofIndexedDB to give developers a first look at experimenting with local storage in the browser.
You have to see it to believe it. Thanks to our upgraded graphics engine, the rendering of text and graphics, including SVG and Canvas, is faster and sharper than ever before. Firefox automatically color-corrects images (like your digital photos) to make sure the colors are exactly as their data intended.
WebM and HD Video
As pioneers of HTML5 video standards, Firefox also supports the WebM format so you can watch open HD-quality video.
Make annoying form implementation development a thing of the past. Firefox-integrated form features like list attributes and HTML validation provide the tools you need.
Firefox now integrates multi-touch support for Windows 7, enabling you to interact with your browser in a whole new way.
Want to know what makes cutting-edge sites tick? Firefox allows you to peek under the hood of dynamic web pages with this experimental analysis tool.
Firefox supports open font formats like WOFF, TrueType and OpenType, meaning site designers are no longer limited to a select handful of web-ready fonts as they create their sites. Because Firefox makes sure to display and render type properly even if you don’t have the font installed on your computer, you can view a wide variety of fonts while you browse.
The Language of Firefox
Firefox speaks your language like no other browser on earth. Because the Web is a public resource shared by everyone, we’ve made our browser available in as many languages as possible. We have over 85 different translations, from French and Chinese to Finnish and Czech.
Emphasis on Accessibility
By minimizing keystrokes, allowing users to zoom in on Web pages and supporting screen readers, Firefox is that much easier to use for those with mobility disabilities and visual impairments.
Go beyond translation and experience the web in a way that makes sense to you. Local developers who know what’s best for their community have customized your Firefox browsing experience with local dictionaries, search providers, live bookmarks and Web feeds. Depending on where you live, you’ll see things like BBC headlines tailored to your region or experience features that work with Baidu, the Chinese search engine.
Better Text Rendering
Read your language as it’s written—more like real life. Our graphics engine renders Arabic, Persian, Punjabi and other script languages in a remarkably seamless way.
