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.

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.

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.

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.

The specific problem i have is that playing HD videos online irrespective of the website is always choppy. but the video plays fine in lower formats like 360p and 480p. i don't think my computer is the problem because similar videos play fine on internet explorer. I use Toshiba computer that's pretty old and i use windows 7. But like i said earlier the same old system plays the HD videos on internet explorer so why not on firefox. am using the latest version of firefox. so i will appreciate any useful solution to this problem as am enjoying my firefox experience up until this point.

I'm having a new issue (it started about a week or two ago) where Firefox runs fine until I try to play YouTube videos. Then Firefox lags for about 1 to 10 seconds. The bar at the top will flash "Not Responding" before going back to normal. This happens numerous times.

I have tried shutting down all other applications, "refreshing" Firefox, turning off Privacy Badger and AdBlock Pro, turning off Shockwave Flash's "protected mode, and even unchecked Firefox's "Use hardware acceleration." So far, none of these fixes work. I even even went so far as to try a HTML 5 add-on for Firefox. So far, nothing has stopped this lagging.

I've Googled and saw a lot of other people with this issue (so it's not just me), but I have yet to find a fix. Can anyone help?

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

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.
