I've been having the same problem and I had a window pop up on Firefox and said that the Real Player plugin was causing problems and asked me if I wanted to disable it.  When I did and restarted Firefox, the flash player started working.

Jerome, thanks for acknowledging that somebody from Adobe needs to investigate what I am reporting.  I believe you guys are a professional and well-run organization and will take my efforts seriously.

I tried your suggestion about selecting "Process Tree" in procexp and that worked.  Thanks for clearing that up.

I seem to have gotten some other responses to my postings.  I'll read those before launching the bug report process.

Thanks again for your reply.

Same problems here (no video on certain sites, Youtube seems fine; Audio is present). Here are some things that WON'T work on my machines (Windows 7 64 bit, Flash 11.3.300.257, FF 13.0 and Ubuntu 11.10; no Real Player Plugin on any of the machines)

- Disabling the protected mode in the mms.cfg file --> DOESN'T WORK

- Disabling all add-ons and extensions (except Flash and shockwave)--> DOESN'T WORK

- Creating a test profile in FF 13--> DOESN'T WORK

- Checking OOPP in FF (dom.ipc.plugins.enabled is set to true and dom.ipc.plugins.enabled.npswf32.dll  is non existant).--> DOESN'T WORK

The only time it works is when FF runs in Safemode with all Add-Ons and Plugins disabled, however if it runs in normal mode and Add-ons and Extensions are disabled by hand it still doesn't work.

And here's what I WON'T DO:

- Creating a new Windows Profile (no thanks)

- Reseting FF (I have no interest in downloading and installing all my Extensions again)

- Rolling back to an earlier version of Flash or FF for that matter

- Updating my graphics driver (Flash worked with the graphics driver before and should work with that version as well).

- Using IE 9 (I'm too used to FF by now, why should I go back).

That's what I WILL DO:

- Disabling automatic updates on both Flash and FF

- Getting Chrome

Thanks google chrome with adobe flash player works like a charm , even

broswing is much more faster and i was able to aply it individual for me  i

dont know why i didn't know it till now Thanks again

Same problem here. Firefox 13 is constantly crashing and freezing. The previous version of Flash worked perfectly fine. I would like to be able to re-download the older version. It's really hard to use the Internet without Flash.

Just got a crash on twitch.tv when coming out of full-screen mode and trying to go to the previous page. Adobe Flash stopped working and caused Firefox to crash.

edit: Just rolled back to 11.2.202.235. I will try it for a while and see how it works.

Chrome, sounds like a plan!  Very disappointed, was so used to firefox; using IE as a temporary measure now :-(

EDIT: you won't see my flash plugin below cuz i disabled it

Thanks for all the tips and here's my paste from about:plugins. I don't have an about:support though (i'm of course having the same issues). Any chance of just an update to flash to  resolve this seemingly widespread bug that renders firefox unusable?

Enabled plugins

Hi Jeromie,

I’m running  firefox 13, I guess it’s set to automatically update.  I found the extensions under tools and then add-ons?

I can’t seem to copy and pace them into this email.  There is something called Adobe DLM which seems to be disabled.  I haven’t sent you the plug-in list so think you’re getting me mixed up.  I would gladly do so but can’t find a way of doing so without typing them all.  I just hope you find a simple fix soon!

Thanks.

I agree with other posters: I shouldn't have to debug Adobe's code for them.  And I don't want to have to reload the operating system (for example) to get this Flash Bug fixed.  I've sent in the bug reports, but for now every time I use my computer "Adobe Flash has crashed" comes up several times.  Clearly, 11.3.300.257 was not tested if there are this many people having this many problems.

I am running Win7 Pro, with all updates current and installed.  I am using Firefox 13.0.1.

Is there any way to redact the update?  How do I get back to a reliable version?

I've never experienced a release this bad in a product as popular as Flash. Maybe Apple's involved. Since iPhones can't run Flash, maybe Apple is paying off Adobe so that nothing runs Flash!

Every time I open Firefox, or a new page, or almost anything - the Flash Plugin has crashed...

Is there a weblink with explicit instructions on how to redact to a reliable version?

I just signed up to let you know that I am also having the same problem ie Adobe Flash Player crashing intermittently.

Windows 7 x64

Firefox 13.0.1

Flashplayer 11.3.300.257

Same problem here.  Two laptops running Firefox 13 have been having issues with Adobe 9 crashing on a fairly regular basis (once every hour or so) over the past couple of days. 

Message says that "Adobe Flash Player 11.3 r300 has crashed".

Hopefully, the technies at Adobe and Firefox will get it sorted pretty soon.

I disabled the RealPlayer plugin - no change.  I did all the other suggestions in the prior posts. 

I don't have any specific examples but I have been watching the Eurocup via ESPN's website stream (ESPN3.com or WatchESPN.com).

As the game in question loads, the app crashes... it may crash several times but other times i just reload and things are fine.   I do not have RealPlayer installed.

Chris Campbell - that actually did work - first time I've seen more than just disabling the plugin.  I was just doing it in the browser.  I have 11.3 installed and working now.

Are there plans to fix the incompatability or are you leaving that up to RealPlayer, or was it by design?

Jerome,

Since the time that you replied to my comment, I have not noticed any significant issues (I have not made any changes).

I will get the occassional crash here and there but a reloading will eventually work (I haven't been able to replicate crashes).

I am running Firefox 14 beta on Win 7 Ultimate Service Pack 1 on a P4 3 Ghz and 1 GB or RAM.

My Firefox privacy settings are set to not store anything in the history folders and also to avoid website tracking requests.

My Flash storage settings are set to the 2nd option (Ask me before allowing new sites to store .....).  I used to have it set to the 3rd option but I had an issue with one website that wouldn't load account info after logging in using that setting.

Firefox has had issues in the last few releases with memory leaks and I suspect that there is an issue here again with the browser but none the less I think the Adobe issue has been minimal for me (I do not have an Real products installed).

For now I have installed the Flash update released today.

I will post again in a few days and let you know I've experienced any crashes what so ever.
