Firefox released, supports Apple’s Mac OS X 10.5 Leopard

Mozilla has released Firefox 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).


  1. Why even bother making this build available?

    Maybe Mozilla was inspired by Microsoft’s Vista debut and their “dam-the compatibility” philosophy. ” width=”19″ height=”19″ alt=”wink” style=”border:0;” />

  2. Woody, there is no need to affix a tinfoil hat to your head. In many cases, an update of any OS, Mac OS-X included, will likely break plug-ins, especially plug-ins that were coded by geeks who thought they were smarter than the guidelines from Apple or Mozilla.

    But don’t worry. Give it a week or two, and you will likely see updates to plug-ins and apps that work better with Leopard. And please filter out all the whiners who complain that this or that breaks when they installed Leopard, in part because they did nothing to prepare for an install of a major OS update. If you’re worried, wait a couple of weeks before making the jump to Leopard.

    Please understand – there will likely be bugs – with millions of lines of code, bugs are impossible for Apple to escape, despite a ton of beta testing. There will be updates and patches issued in rapid succession by Apple and third party developers in the next 3-4 weeks. But once the smoke clears, it should be pretty amazing.

    So let the early adopters do their thing. There’s no deadline to make the jump to Leopard. But if my experience is any guide, I’ve been using OS-X since the first day it came out as a beta. And I have never encountered any bugs in my personal experience. Your mileage may vary. But let’s put it this way: if you were an Apple developer, would you want to upset your boss, Steve Jobs?

    I didn’t think so.
