The issue with Adobe Flash and Firefox is an issue related to how Adobe created their "Protected Mode" in Flash. Downgrading to a previous version of Flash is basically the same as disabling this protected mode, and lets Flash work with Firefox. It isn't a fault with Firefox as it is Flash's QA team missing some bugs.

Flash in IE works because IE uses a totally different version of Flash than Firefox (and chrome uses another different version). These different versions have different bugs (there are bugs in the IE flash that aren't in the Firefox Flash, etc.).

Using the latest version of all your software is always the ideal situation, but sometimes, you have to downgrade. Downgrading Flash is the best overall solution, as in a typical day web surfing, you are going to be using Firefox more than Flash, and thus will want the security benefits in Firefox being updated. Also, there are reports of older versions of Firefox not working properly with the newest flash as well, so downgrading is the only surefire way to avoid problems (until Adobe fixes their problem)

yeah, thanks for that, but surely you can see perhaps 3 or 4 months down the road, then what? Eventually things are so far out of date that nothing works anymore. If you play to the mantra of always keep up to date software, that means all software, you can't have it both ways.

No, you don't want to keep Flash out of date always. Hopefully Adobe will be releasing a fix within a few days/ week, so once that updates comes out, simply update, and enjoy using the most up to date software again :D

Surely it's Adobe Flash that's at fault not Mozilla Firefox? Adobe have released a product that has not been sufficiently tested.

It is out 11.3.300.262 http://get.adobe.com/flashplayer/ but as John99 said in : https://support.mozilla.org/en-US/questions/930263 "We have not yet received many reports" for the new version

thank you

v11.3.300.262 has fixed the issue for me.

V11.3.300.262 is about a 90% fix imho, so thanks for you folks finding that. Videos that used to be smooth playing are still herky jerky at the beginning and in parts during play, vs smooth and jitter free in the past (and are still smooth and jitter free using IE9), but the constant player crashing is fixed. Maybe the next update........ sigh.

Thanks for the info emteec & cjack99.

Whoopsie,,,,, nope,,,,, still crashing, it just takes longer, and now there is an added benefit, it tries to lock up Firefox as well when it comes crashing down, and does a fairly decent job of it too. Bottom line, v11.3.300.262 is NOT a fix.

Do you have crash IDs for recent crashes with the Flash 11.3.300.262 version installed?

If you have submitted crash reports then please post the IDs of one or more crash reports (bp-xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx).
You can find the IDs of the submitted crash reports on the about:crashes page.
You can open the about:crashes page via the location bar, like you open a website.

This is Greek to me, but I tracked down what I assume is the crash report from the latest installment of the play, based on the link you provided:

Crash ID: bp-85bc894e-b5ed-4038-82aa-015312120621

Dunno if that helps or no........

This is still a crash related to the plugin-container process and probably the Flash plugin.

If you can't get Flash 11.3 to work then maybe try to revert to Flash 11.2.

You can download the Flash 11.2 player via this direct link:

You need to uninstall the Flash 11.3 version if you downgrade Flash.

Found a solution here: http://forums.adobe.com/thread/1029369 Apparently Real Player is the reason why things are not working. I believe the problem is more on Adobe's end, but I am not sure. Either way, uninstalling real player worked for me, but if you disable the download plugin and keep it from downloading at all, it should work.

Yep, I agree, I found essentially the same thing, when I was running speed tests (another issue I've got with Firefox now) I discovered the roadblock is the flash plug-in. And, I'm NOT about to go through all the shenanigans required to make it work. Also, I don't care about the finger pointing (it's adobes fault, it's firefox's fault, it's protected modes fault), that all BS. Personally, here's the deal, IE works, Chrome works, Firefox don't work anymore. It's that simple. I don't care if Firefox is technically superior, I don't care that's its non-profit, I just want to seamlessly be able to surf the web and view videos, at the same speed I had before, and that is no longer do-able with Firefox. Sorry Firefox, you are OUT. And no, this issue is NOT FIXED until Firefox will play with Adobe, without a bunch of computer geek fooling around. C ya'll, maybe I'll try Firefox again in a year or so, maybe not.

Sorry to see you go cjack99.

Note it is possible to have more than one browser installed if you wish you could use Firefox for some things and another browser for Flash. Also note this article

• Export Firefox bookmarks to an HTML file to back up or transfer bookmarks and the articles that then links to

I do not think this mess should have happened, but it has and some of us are still sticking with Firefox, if so note that a very recent update of Real Player has been made and part of the reason behind that may be an attempt to resolve some of these issues.

Ok, I am a very loyal Firefox user for many years now. However I've been having similar problems as of late. In the past year or so I also noticed Firefox has become notably slower. Especially while playing youtube videos - during playback the image froze for a second or two every 10 seconds while the sound kept going. You can imagine how annoying that is. Also since the latest update of flash - 11.3 youtube videos and facebook games can't be opened anymore. I read somewhere that I had to disable the realplayer download browser plugin in order to make it work. What kind of bs is that? I love realplayer's download option, I use it all the time to make my own offline library of favourite videos. I want to keep using it. (Not gonna complain about waiting for the month-long delay of real player catching up with every firefox version update to make it work again). Anyway what I do now is downgrade flash to 10.3 which requires some time for searching for the old version, uninstalling, installing, restarting etc. All this is annoying. Then sometimes when I'm not alert enough I am notified about some adobe updates and fall into the trap of upgrading again and there goes the whole cycle one more time. I don't understand why there have to be such problems when we are encouraged and even pushed to use the latest version of both firefox and flash, yet when we do we can't use one of the most popular and used websites at the moment - youtube. :/ Am I missing something?

The problem is that Adobe released a version of Flash (11.3) that causes problems in Firefox. There aren't problems that Firefox can do anything about, they need to be fixed directly by Adobe. There was also an issue where RealPlayer Downloader was interacting with Adobe in a way that caused crashes as well. However, Realplayer has released an update that should fix that.

Right now, as we wait on Adobe to release it's fix, the only option is to downgrade to an older version of Flash, and not upgrade for awhile. Hopefully in a few weeks this will be all fixed :)

Well, I just had to reply, just to report in plus I'm still getting email notifications of activity here.

So, here's the report: A month ago I totally blew away all vestiges of Firefox (after saving off my cookies and bookmarks of course (there is a utility you can get that will put the cookies in IE understandable format, great benny that). I let win7 install ie9, imported my bookmarks and cookies, and I've been a happy camper ever since. ie9 is faster than I remember Firefox ever being, and guess what? What? (you say). Youtube, no problem, video links, no problem, speed, no problem, audio players, no problem. Here's a biggee,,, NO FIDDLING AROUND WITH ARCANE IDEAS LIKE TURNING THIS OFF, OR ON, OR DOWN REVVINH, OR WHATEVER, ie9 just works, which is what I wanted in the first place, and which Firefox used to do. Again, to restate, I don't care WHAT caused the issue, or WHO's fault it is, Firefox ceased to be a viable tool for me, and it's no longer in my toolkit.

Honestly, no one is going to download IE just for a workaround. Almost everyone will agree IE is a horrible browser. And with a few of their updates, Flash Player is better. But still not great. I think part of the problem is that they are running their own processes in addition to the plugin process for Firefox and Firefox itself. It's taking up too many resources, and while Adobe may have thought this helpful, it basically kills everything.
