since I upgraded to the latest version of firefox - 16.0.2 on my Mac, it crashes/hangs all the time and I get more unresponsive script alerts and the spinning beach ball of death from apple (this spinning wheel/ball is the sign of a crash/hang); and when firefox crashes/hangs I have to force quit and then restart the machine, because it also takes out the ability to work from different work spaces in mission control. I can’t move or navigate between work spaces. Please advise. This is MUCH worse since I put on the new update, but has been getting worse in recent updates. I also notice a huge up spike in notices of an unresponsive script alert and sometimes that brings up the beach ball as well. I do use firefox heavily and it has been good until the last 4-8 weeks or so, but I can’t continue to use it if it keeps getting worse. I always have 2 ff windows open with about 15 tabs each and this hasnt been a problem for about 10 months or so, since I moved on to the platform, but it is now a problem and I am having a hard time justifying the time I spend on this versus troubleshooting when I am not using it any differently or with any different sites than before - please help and follow up. Thank you.
