Firefox crashes every time when I enable a flash plugin. It started today after an automatic attempt of updating shockwave. I've uninstalled flash and installed it again. Still the same story. There are no previous version of flash available on adobe site. What should be done?

From the menu do Help -> Check For Updates and follow the instructions to get 3.6.6 which will stop Flash crashing Firefox.

I have Firefox 3.6.8 and newest version of Flash. I've followed all recommendations made by Firefox support, changing plug in container settings, changing hang time, nothing helps. I'm forced to disable Adobe Flash or Firefox crashes whenever the Flash plug-in is needed. There are numerous reports of this problem throughout the Firefox troubleshoot help pages. No one seems to have a good answer to fix this. I now keep Flash disabled and use it only when going to a web page that needs it. If I find myself on such a page, I can go into tools, enable flash and do a reload. For some reason, this works. The reload will let Flash do its thing and Firefox won't have an APPCRASH. Once I leave that page, however, I must disable Flash again or I'll experience a crash the next time Flash is called upon. I really like FF but have downloaded Chrome and am now playing with it to see if I like it enough to use it as my primary browser. It's a shame that FF can't come up with a fix as hundreds have the same complaint.

Try disabling hardware acceleration in your Flash Player display settings (Right-click on any Flash video, click "Settings", select the Display tab and uncheck “Enable hardware acceleration"). Ref: http://kb.mozillazine.org/Flash#Performance_or_display_issues_with_certain_Flash_videos

Running Firefox 3.6.11 on Mac OS 10.6.4. Firefox crashes as soon as Flash is enabled

ssour, I have exactly the same problem. I haven't gotten any support though. I need to switch back to Safari. Oh well.

Are there any solutions to this? It basically makes Firefox incompatible with Mac OS 10.6, no?

Mozilla Firefox crashes after updating to latest Flash Player. Straight after it opens.

I have FF 3.6.13 and it was still crashing with Flash Player 10.1.

I read a lot of pages on this and one finally gave me a solution. The current Flash Player has a bug. To test that, go to Tools>Add-ons>Plugins and turn off Shockwave Flash. Then try to go to CNN, the New York Times, or Yahoo Mail. If it fixes the problem, then this buggy Flash Player is at fault.

It was suggested that you download the beta version 10.2 here: http://labs.adobe.com/downloads/flashplayer10.html

Just pick the one that says: Download plug-in for 32-bit Mac OS X32-bit (DMG, 5.5 MB)

This fixed it for me.
