I have Mac OS 10.5.8 - can I download an earlier version of Firefox? The one on the site is for OS 10.6.0.

I'm encountering some sites that don't support Safari so I have to download Firefox. But I use Mac OS 10.5.8 and so I'd need an earlier version than the one available on your site for download. Can you help?

All of the earlier version are sorted here:


Firefox All Releases

However I think your OS is supported, too. Check here:


IMPORTANT NOTE: Don't forget that the previous versions have security problems. For the latest security updates you MUST upgrade to latest version. That's what I STRONGLY recommend. Thanks! Don't forget to hit 'Solved it'.
