Lifehacker has a great post on tips and tricks for Firefox 3. Favorites include deleting mistyped URL’s in the new URL suggestion window and auto-complete entries (I hate when my mistakes get saved!), making web applications like gmail launch instead of default desktop apps, enabling spell-checking in single line input fields (as apposed to just textareas), and lastly, for Mac FF3 users with the default Safari skin, adding favicons back in your bookmark toolbar.

So the new Firefox 3 that was released last week is awesome. It’s much faster, doesn’t seem to hog memory as much as the old one, and has a completely revamped bookmarks system which I enjoy. Mozilla reached it’s goal of getting in the Guinness World Records for the most downloaded application in a single day (8 million) and if you haven’t downloaded it yet I suggest you try it now.

Generally though, FF3 is definitely worth the upgrade and besides the two issues above I experienced on my own project, I see no issue on the regular sites I visit.
