A free and open source web browser descended from the Mozilla Application Suite and managed by Mozilla Corporation. To display web pages, Firefox uses the Gecko layout engine, which implements most current web standards in addition to several features which are intended to anticipate likely additions to the standards.
Latest Firefox features include tabbed browsing, spell checking, incremental find, live bookmarking, a download manager, private browsing, location-aware browsing (aka "geolocation") based exclusively on a Google service and an integrated search system that uses Google by default in most localizations. Functions can be added through add-ons, created by third-party developers, of which there is a wide selection, a feature that has attracted many of Firefox`s users.
Private Browsing:
Surf the Web without leaving a single trace.
Password Manager:
Remember site passwords without ever seeing a pop-up.
Awesome Bar:
Find the sites you love in seconds (and without having to remember clunky URLs).
Super Speed:
View Web pages way faster, using less of your computer’s memory.
Anti-phishing & Anti-malware:
Enjoy the most advanced protection against online bad guys.
Session Restore:
Unexpected shutdown? Go back to exactly where you left off.
One-click Bookmarking:
Bookmark, search and organize Web sites quickly and easily.
Easy Customization:
Thousands of add-ons give you the freedom to make your browser your own.
Tabs:
Do more at once with tabs you can organize with the drag of a mouse.
Instant Web Site Id:
Avoid online scams, unsafe transactions and forgeries with simple site identity.
Security & Privacy:
Instant Web Site Id:
Want to be extra sure about a site’s legitimacy before you make a purchase? Click on a site 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.
Private Browsing:
Sometimes it’s nice to go undercover. When this feature is enabled, you won’t leave a single browsing fingerprint behind for others to discover. You can slip in and out of private browsing mode quickly, so it’s easy to return to what you were doing before as if nothing ever happened (you can also browse privately all the time).
Forget This Site:
Having second thoughts about having visited a certain Web site? With this feature, you can remove every trace of that site from your browser—no questions asked!
Anti-malware:
Firefox protects you from viruses, worms, trojan horses and spyware. 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. Firefox checks every part of a Web page before loading it to make sure nothing harmful is sneaking in the back door.
Anti-phishing:
Shop and do business safely on the Internet. Firefox gets a fresh update of web forgery sites 48 times in a day, so if you try to visit a fraudulent site that’s pretending to be a site you trust (like your bank), a browser message—big as life—will stop you.
Parental Controls:
Enforce parental control settings you’ve entered on Vista—stop unwanted downloads and more.
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.
Customized Security Settings:
Control the level of scrutiny you’d like Firefox to give a site and 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.
Add-ons:
Firefox looks for a secure connection before installing or updating add-ons, 3rd party software, and Personas.
Password Manager:
We’ve seamlessly integrated this feature into your surfing experience. Choose to “remember” site passwords without intrusive pop-ups. Now you’ll see the “remember password” notification integrated into your view at the top of the site page.
Anti-virus Software:
Firefox integrates elegantly with your antivirus software. When you download a file, your computer’s antivirus program automatically checks it to protect you against viruses and other malware, which could otherwise attack your computer.
Pop-up Blocker:
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.
Automated Update:
Our open-source security strategy lets us find—and fix—security issues in record time, making Firefox the safest way to surf. Install upgrades when you receive automatic notification or wait until you’re ready.
Super Speed:
Fasten your seatbelt: Firefox 3.5 includes the TraceMonkey JavaScript engine, which gives the browser dramatically better performance than ever before. Firefox has always been fast, but this is the fastest Firefox ever (more than twice as fast as Firefox 3, and ten times as fast as Firefox 2), meaning Web applications like email, photo sites, online word processors and more will feel snappier and more responsive.
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.
Newest Web Technologies:
Brand new and enhanced functionalities enable Web site authors and developers to create advanced content and applications. Support is now available for:
Expand the power of Web-based applications. In the past you’d click on an email address in a Web site and your computer’s default email application would open up to send a message to the linked address—even if you never email through the program. Now you can choose a Web mail clients (like Hotmail, Gmail or Yahoo! Mail) to launch when you click on that email address.
