Firefox 3

Firefox 3 was released today, and they are trying to set a world record for the number of downloads in a single day. Get yours now!
To learn more about how to use it, download/check out this Field Guide to Firefox 3. (HT to Jane's.)
I've used it for a few hours now, and here are some things you should know.

• The Firefox server has been pretty busy, so it took me a few tries to get the download. It is less than 8Mb, and installation is quick and painless.
• The upgrade does check all your addons, tells you which ones won't work with the new version, and will search for updated addons that will work.
• For now, the ones I regularly use that don't work are:
  • My del.icio.us one click link
  • Google Browser Sync which I always had active >> UPDATE: Iyov in the comments points to a website indicating that Google Browser Sync is being abandoned and will not be updated. They recommend Foxmarks. I had used this before and will now return to it to keep my computers in sync. Actually, I can log in to Foxmarks and have my bookmarks available on any computer anywhere. Thanks, Iyov.
    
  • iBreadCrumbs which I described in an earlier post
  • Personas for Firefox which provides some simple themes
  • Resurrect Pages - This one I regularly use to pull up dead web pages via a variety of archiving engines >> UPDATE: This is now updated and works in version 3.
    
  • Themes - I'm not big on themes, so this is no big deal
  • Tab Mix Plus - Another one that I used regularly

I trust that those addons will be updated soon to function in Firefox 3.

A couple other observations:

• The rendering of pages is noticeably faster.
• The default theme and the new icons are clean and attractive.
• All of your Firefox 2 preferences and customizations are retained in the upgrade (except for the addons that don't work).
• Some of the other important addons for me (Zotero, FireFTP, ShareThis) work perfectly well.
• So far it has been entirely stable. I say, "Go for it!"
