I am having the same problems that these other 2 posters are experiencing. I keep getting popups saying that my Flash Player and the plugin for Firefox has crashed or stopped working.  I am using Vista Home Premium 64-bit desktop PC and I am using Firefox 13 as my browser.

These problems did not occur until this last update for Flash.

I have did that like 4 times! and still a flash player crash.. and this crash didn't happen before the update.. :/ I highly believe it is a bug in flash player.. ;/

the same here for me:

...this looks as a "less silent" crash when I close FF I see the silent crash in the "pending crash" folder and... >windows vista crash report< tells me:

==>>> very important:

disabling protection mode in flash 11.3, all is ok!!!

no crash (because > no additional processes in task manager _flashplugin_-- that conflict with container ,) I guess, the new flash processes let firefox to not close (better: to not find!!) the container.exe> crash of the container after closing firefox.

I added my dump.zip repost PLUS this message from windows that quotes the container and the flash plugin.

By setting protected mode to 0 looks like an temporarly workaround.

=> reset firefox to the defaults offers no valid resolution!

Pls fix it. I had this problem for 3 days on Win7 64bit FF13.

I just downloaded Flash 11.3.300.257 and am running Firefox 13 as we speak.  I have Win7 SP1 64 bit and have not encountered one error yet....and I've tried multiple sites.  From many reports, this seems to be isolated with Vista and Win7 running protected mode, but XP seems to be unaffected.  Is XP affected by this reported problem and is Adobe going to release anything formally on their bulletin site regarding the affected platforms?  .......Or.....is this a Firefox 13 issue with incompatability between it and the new Adobe Flash Player update?

After a doing a test installation of Flash Player 11.3.300.257 to about 10 PCs in our Win7 64-bit environment, we have experienced Firefox hanging and acting unresponsively on nearly every one of these PCs, whenever opening a website with Flash content.

We are using Firefox 10.0.5 ESR so this issue is not only on Firefox 13. Setting ProtectedMode=0 appears to remove the problem.

11,3,300,262 installed

the changelog please,

because I still notice the issue: ff loses the focus when you open a tab with flash the first time!

??!!

thanks.

PS: at the moment no audio problems

Ok, Chris, thank you for your reply.

I guess that the bug in bugzilla should be filed yet...

but you know now:

no focus issues when you see the processes in task manager. ok.

after a while, when the processes disappear from task manager, when you first open a tab with flash (YT or other sites), then FF looses the focus. (flash 300.262 too. no issues with protedtedmode OFF

No idea...perhaps Mozilla will fix this issue (as happened with the silent crash, thanks to FF 13.0.1 ? and the changes added inthe container's code?)

Union,

(ok, my problem regards the focus only),

but please take care: a lot of people dont want to disable acceleration in ff, otherwise all the fonts become very bad (unreadable). In some configurations FF's acceleration is strongly *needed*

Union, do you are noticing the focus issue in FF, when the flash/container processes disappear from task manager?

hey, with or without processes in task manager? or booth situations?

this were the first time I hear this good news.

all people that I know have this issue (with protection mode ON, and processes cloased in task).

Chris, if you want it may be of some interess to read the dxdiag from my pc and from the Uniomn's laptop well?

(via PM obviously

No Stability problems here.

!!!!!

Hey Chris,

here my first crash: flash crash (feedback has been sent)

1) open all these videos

2) workaround: change video quality to get all the videos buffering in pause mode.

3) all the videos are ready for watching.  flash plugin RAM : 800MB!

4)

http://www.youtube.com/watch?v=DOmFcKiHPgM&feature=plcp

play this video. full screen mode.

5)

then, after a few seconds, move the pointer to return to the beginning

=> 6) the video exit the full screen mode > expanded mode with a " ! " in the video window.

7) flash plugin does crash

8)

send the feedback

9) reload all the videos. now the flash ram = 400MB!!!

never seen a flash crash in the past, even if I did open 15 YT videos 1080p.!!

please watch these reports:

crash: bp-e3b86a68-f646-4136-ba96-77f212120623

crash: bp-8d7717ae-0af2-4486-8a05-ab39f2120623

why 300.257 worked fine and 300.262 is very bad??

I cannot understand....
