I seem to have the very same problem on Windows 8 (x64) on Firefox 19.0.2 (x86) having the latest Flash Version installed (11.6.602.180 -> released today)

• Check for Malwares.

You can check for problems with current Flash plugin versions and try these:

• disable a possible RealPlayer Browser Record Plugin extension for Firefox and update the RealPlayer if installed
• disable protected mode in Flash 11.3 and later
• disable hardware acceleration in the Flash plugin

RealPlayer Browser is disabled, but is they're a way to disable protected mode in flash/hardware acceleration? It's not on the global settings manager and I can't go on youtube to change it because it freezes and it won't let me go onto the settings. :( If I degrade Firefox and flash, and install it on another PC which didn't have firefox would it work? And it never crashes so I wouldn't get a crash log...

@Gruntkiller4000 even though it did not give me a crash message while it was freezing it did add a crash log to the about:crashes page. You can click on it to see if it is flash related. (It takes some time so see the report the first time you click on it.)

I did disable the protected mode for flash (http://kb.mozillazine.org/Flash#Disabling_Protected_Mode_in_Flash_11.3) like cor-el suggested and now my firefox is working again - thanks for the hint!

I have begun having this problems on both of my machines. One is running Vista and the other Windows 7 home premium. Both are fully up-to-date. When a page contains flash content, Firefox's memory usage continuously increases to the point that FF crashes.

The problem started after I selectively blocked images and objects via Tools>Page Info>Media on a page that I was on. Firefox has become totally unusable if I have Flashplayer enabled and a page contains Flash content. I have disabled Flash in Firefox, but have to use Chrome to access sites where I must have Flashplayer enabled.

Hopefully this will be corrected quickly.

You can inspect and manage the permissions for all domains on the about:permissions page.

Thanks for the information regarding about:permissions. It will make it easier for me to manage site permissions in the future.

However, something that I have and want blocked is causing Firefox to crash. I'm confident that it has something to do with Flashplayer, but right now my only recourse is to disable it and use Chrome for sites that I need to get to that require Flashplayer to be enabled.

I've tried using about:permissions to selectively manage myspace.com. Unfortunately, it is not in my list of sites, and I can't find a way to add it. Also, the site list appears much shorter than what I would expect it to be.
