Mozilla slates Firefox 5 update to fix Lion crash bug

'Out-of-band' update only for Mac users

Computerworld - Mozilla on Friday said it would update Firefox for the Mac to deal with a bug in Apple's impending Lion operating system.

Firefox 5.0.1 is "coming soon," Mozilla announced in a blog post, but did not set a release date. Users running Microsoft Windows or Linux will not see the update.

According to Mozilla, Mac OS X 10.7, aka Lion, contains a bug that causes Firefox 5 to crash when displaying websites that use downloadable fonts.

"We alerted Apple to the problem before the release of 10.7 but they did not fix the problem before 10.7 went to final release," Christopher Blizzard, Mozilla's Web platform director, said on the company's blog. "We've changed the font APIs that we're using to newer versions which appear to fix the problem."
