Top 10 Firefox 3 Features10. Souped-up Add-ons manager
A big part of what makes Firefox so special to power users is its extensibility with extensions, add-ons, plug-ins and themes, and Firefox 3's Add-ons dialog got the attention it deserved. The Fox's Add-Ons menu is more robust and intuitive on at least two fronts. You can search and install extensions and themes right from the pop-up box, no browsing required. Also, a new plug-in manager lets you enable and disable third-party helpers like Flash, QuickTime, and anything else that makes content work (and causes you grief).
9. More intuitive interface overall
Mozilla tweaked and updated a whole lot of little things here and there throughout Firefox 3, which amounts to a big overall boost in usability. Most noticeably when you first switch, the Back button only appears on the address bar if there is a page to go back to, and when it does, it's bigger and easier to click. Users who want to make sites with small text more readable permanently are in luck; Firefox 3 can increase the size of images and text, or just the text, on hard-to-read sites. In addition, Firefox 3 applies favicons more consistently to bookmarks, you can click a site's favicon to get extended site identification information, you can resize the search box to hold more than two words, and the find-on-page search box automatically grabs the currently selected word, just to name a few new UI improvements.
In the long term, once webapps catch up, Firefox 3 will let you do really neat stuff in your browser, like register your favorite webapps to open certain file types, and access your online data even when you're not connected to the 'net. To get a taste, see how you can configure Firefox 3 to launch Gmail for mailto links.
7. Improved download manager
Never wonder where a download came from, or went to, again. Gran Paradiso's download manager lets you search through recent files, resume big downloads after a crash or restart, and lets you keep an eye on your transfers in the status bar.
5. Streamlined "Remember password" handling
No more guessing whether you're saving the right password or clicking "Cancel" on unnecessary pop-up requests. Gran Paradiso only asks you to utilize its password-saving function once you're already in and sure everything worked, and it won't block you from seeing the logged-out version of a page if you don't want to sign in.
I use Firefox 3 Beta 5. This
IS a sweet feature. It pops up like a pop up request so you wait until your sure that the password is correct & your nice and logged in before you save the password.
1. Insanely improved performance
It's not flashy, and it doesn't have any social networking features, but Firefox 3's actual performance is the best reason anyone should consider upgrading, or making the switch to the 'fox. Firefox's engineers claim that their third major release is 9.3 times faster than Internet Explorer 7 in JavaScript performance, and 2.7 times faster than Firefox 2. This means snappier browser performance when you're using webapps like Gmail, Remember the Milk, and more. Even more important, especially for Mac users, is the improved memory usage and more than 15,000 improvements that make for a less crash-prone browser. I've seen noticeable speed-ups in page loading in Linux, XP, and Vista, but the real reason I've switched over to using Release Candidate 1 is that I haven't had to cross my fingers every time a Flash-based video loads.
