Videos on Twitter don't play, "The message This browser does not support video playback." appears on the center of a screenshot of the video. Twitter Videos play normally on Chrome. YouTube videos play normally on Firefox.

I have the latest version of Firefox and all the plugins are up to date (Java, Flash Player etc). I have experimented changing Hardware Acceleration Where Available box, the media.windows-media-foundation.enabled attribute, clearing the caches, opening in safe mode, nothing makes the videos play.


Is there anyone who has had the same problem and managed to solve it. Thank you.

48.0.2 on Mountain Lion 10.8.5. Fullscreen video on the CNN site plays initially, then stops with a circling round arrow. Lately it has started to do this with that video on the side as you scroll down the screen, as well. Very maddening. No problems on other sites. If I cannot fix this quickly and simply I will have to go to Chrome. Updated flash yesterday, no joy. Suggestions welcome. Thank you

"The Adobe Flash Plugin has crashed." Why? Why does it do it on every computer that I am using, despite the fact that flash is the most current version. Why?

Every time I try to get to any page that uses Adobe Flash, I get the error message. I use three different computers and it does it on all of them, but only in Firefox. It is really annoying and I have tried all of the suggestions on your support page: https://support.mozilla.org/en-US/kb/adobe-flash-plugin-has-crashed

How do I find out what is going on to make it STOP?

Nothing seems to work. An appropriate plugin seems to be installed and, after downloading the latest version from Adobe, a retry informed me that Flash was already installed. Firefox does not agree. The download from Adobe informs me that upgrading is a 3-stage process but takes me no further than stage 1. This used to be a doddle under XP. You just found and ran the executable file in the Download folder. I can find no executable files in my Download folder. My current Linux version is 18.3 Sylvia. I am sure that this used to be handled automatically by Firefox updates in previous Mint versions. Now, however, it doesn't seem to matter what I try - whether using the Mint's Software function or going onto Adobe's download page. I always seem to finish up in the same place with the computer just looking at me and declaring that Flash is already installed. The Firefox Addons list includes Flash but nothing I do will get it working.

This only started earlier last week, or late the week before. EVERY YouTube video, does not matter which one, who uploaded it, or when it was originally uploaded, EVERY video causes Firefox to hang for up to 10-15 seconds, ever time. And it hangs a second time if I scroll down far enough to load the comments section. So far, all I've seen being used now is the HTML5 player on YouTube, so it's something with that possibly. Regardless, it is incredibly frustrating.

Is this due to something changing with the last couple updates to FireFox, or a plugin I have being out of date (even though they all say they're fine)? If not, is there anything I can do to fix it?

I keep trying to reset Firefox, enter it in safe mode, disable add-on/plug-ins and nothing works.

When I pull up a youtube video, the video stays on a black screen and the video thumbnails are plain white. Also loading is almost instantly stopped when pulling up a video. When I visit other websites (Gaia Online mainly) and I scroll over a tab that would normally drop down a list of links to click on, nothing is dropped/opened.

Firefox/Flash seems to crash at least a couple of times a day.

I updated Flash in Firefox 42.0 to version 2.0.0.235. It crashed 90% of the time, even with hardware acceleration off. It does not crash with Flash Protected Mode turned off. I then updated Firefox to 43.0. Flash crashes every time, even with Flash Protected Mode off. No Flash problems on this Win-10 PC with Microsoft Edge or Chrome. Seems that FIrefox 43 and Flash are incompatible. Hopefully Mozilla and/or Adobe will fix in the next release.

Using Windows 10, FF 55.0.3, Shockwave plugin 27.0.0.130, Adobe Flashplayer 27 NPAPI.

I am using Adobe Bridge and select to preview a gallery in the browser. Bridge will let FF start and then I get the message (in FF), that there is no flash player installed. I installed many many times, as decribed here in several messages, so often the flash player. I also did the steps described by the college student "ComputerWhiz" (=Wesley Branton) here: https://support.mozilla.org/nl/questions/1037689 (renaming pluginreg.dat). I disabled my virus scanner (E-Set). Also I deactivate in FF all the Extensions (to be sure no one causes a conflict), restarted FF but still FF does not recognize the flash player.

Please help me and do not give answers like to find out which flashplayer version I have or where to download flashplayer. Just an answer straight to the point why FF does not recognize the installed Adobe Flashplayer and how to solve it. Thx in advance

I have been having frequent issues accessing certain websites that I use daily for work. The only fix I have found is to update my adobe flash even though it is current. When I do that and Firefox restarts, I am then able to access these websites.

However, this is a huge burden and I'm ready to pull the plug on using Firefox unless someone has input.

Hopefully it is a quick fix that I'm just not noticing? Everything was fine until Monday 2/26/18. Since then I'm constantly having to fix it.

Flash Player 32.0.0.101 Firefox v64 (64-bit) Windows 10

With this configuration Flash content does not work.

On Windows 7 Enterprise, the same version of Flash Player and Firefox

It looks like it is trying to load under Windows 10 but ultimately what is displayed is a blank screen.

Is anyone else running Windows 10 with Firefox and Flash Player and getting it to work. I cannot post the URL because the application is a inhouse application and requires logging in.

In some, not all, cases, whenever there is a video embedded on a website, there is a blank screen where the video is supposed to go. Youtube will usually work, but not the format of the video below. I know it's a browser issue since it displays just fine on Chrome (I've included screenshots). And I'm sure I have the latest version of Firefox and Flash

Unlike other posters who describe crashes while trying to stream Netflix due to Silverlight issues, the movies will in fact stream, but so slowly they are unwatchable. The audio keeps going but the video freezes and then skips. This has only begun to happen with the last 1 or 2 Firefox updates, and the last update is what has made Netflix unusable. I've spoken to Netflix tech support and their suggestion was to install Google Chrome and use it to stream Netflix. I will do this if I must, but would prefer Firefox if you folks can come up with a fix for this.

For the past few months or so, Firefox has become completely unusable for me. About every five minutes or so, the browser freezes, and I have to kill the process in order to re-launch it. I've tried clean uninstall/reinstall, removing all add-ons, etc. Nothing seems to work. I've installed it on 4 of my computers, and it freezes on all of them (Windows 7 Ultimate, Windows 7 Professional, and Windows 10).

Has anybody had any luck fixing the instability, or am I just stuck with Chrome?
