Mozilla has released Firefox 22.214.171.124 which is compatible with Mac OS X 10.5 Leopard, although there are some known issues:
• On OS X 10.5 (Leopard), there are known problems with some media plugins as well as Add-ons that contain binary components. Also, the tabs in Preferences > Advanced will not render properly.
• The “Close Other Tabs” action on the shortcut menu of a tab can fail with an error when more than 20 tabs are open.
• Some users have reported problems viewing Macromedia Flash content on Intel Mac computers. To work around this problem, users can remove or move the PowerPC version of “Flash Player Enabler.plugin from /Library/Internet Plug-Ins.
• After installing a new plug-in, Firefox may continue to display information for the older version of the plug-in in about:plugins. If this happens, quit Firefox, delete the “pluginreg.dat” file from your profile folder, and relaunch Firefox.
• Java does not run on Intel Core processors under Rosetta.
• There is no Talkback on Intel-based Macs when running natively or under Rosetta. The Apple Crash report program should launch in the event of application crashes.

MacDailyNews Take: It’s kind of like those TV drug commercials – it’s wonderful for whatever ails you, but be advised that it may also may cause brain damage, weight gain, profuse sweating, and hair loss (in other words, you could be Ballmerized).
