I just started having problems with version 10.0.2 of Firefox on my Mac running OS X 10.7.3. I haven't been able to make any connections. I can't close it normally and need to force close it. It has worked fine up until now. I don't know when it did an upgrade to this version (it does so automatically and I probably missed noticing the last change). Has anyone else had issues with this version? Is there a repository for older versions? I have reverted to Safari for now.
