Mozilla is going crazy these days and patch security vulnerabilities en masse! The latest update 3.6.3 even removes support for Java 64-bit! Is downgrading to Firefox 3.5.9 a solution?
It’s great that Firefox is so concerned about security and is trying to fix whatever they can, but they can’t remove support for one of the most important plugins without explanations.
A temporary solution is to downgrade to Firefox 3.5.9 that Mozilla still supports until August 2010.
Hopefully, Mozilla will be able to fix this soon.
