Version 3.6.19 will work on OS X 10.7 Lion

Downloadable font support has been turned off in 3.6.19 on Lion due to a bug in Lion. The bug was causing Firefox to crash.

Thanks Tony! I went ahead and upgraded to Lion and am using Firefox 3.6.19 with no issues so far.

Please click the Solved It button next to the answer that answered or solved your Firefox support issue, it appears when you are logged in, so this thread gets marked as Solved to help other users who may have this same problem.

While I appreciate Tony's post, it did not solve my problem or necessarily answer my question. That's why I didn't check the Solved It box. Firefox 3.6.19 works in the Lion environment and I discovered that by proceeding with the OS 10.7 update on my own. I don't see a Solved It box next to my name.
