I'm positive it's not a virus because I can run every other executable I can find

Problem is with mommy Mozilla trying to protect you. If you visit MozillaZine you'll find others with the same issue. Version 45 will help but you must load the latest version of Flash or FF will block it. There are ways around this but I'm not ready to go there on this forum.

I think that you get that sort of error when there's a problem with MS Visual C++ (version or security update missing) or corrupt version that needs removal and then reinstalling.

Thanks for the screenshot.

I can replicate the problem using Cyberfox (Firefox 64bit variant).

1) Tested Twitter video playback in Cyberfox and it worked fine.

2) Modified preference media.windows-media-foundation.enabled
and set it's value to false

3) Restarted Cyberfox (Firefox) and get the following error:
Firefox won't play twitter videos-twitter-video-cyberfox.jpg
If I undo the change then Twitter videos will play.

So to test - launch firefox and in the address bar type:

about:config

Accept the warning. In the search box type:

media.windows-media-foundation.enabled

Set it's value to true by double clicking.

Exit Firefox and launch it again. Try playing a Twitter video.

Of course this will not help if that preference is already set to true

In addition you might want to check that the following preference is also set to true
media.mediasource.enabled

Anyway, I'm certain this will fix his problems with video playback. Thanks for this

It should show up in profile info (about:support) and looking at the list of modified preferences that were already posted - it doesn't show up so I guess that it's not the problem!

Anyway if it's any help Twitter video works for me and here's my list:

@ randomwin7user

Did you delete your last post?

Anyway you seem to have stated that those preferences do not exist. They should.

Suggestion:

Backup bookmarks, extensions and additionally make a backup copy of your Firefox Profile and profile.in file but keep them stored away from your AppData directory.

Fully remove Firefox (add/ remove programs will not fully remove it) and reboot. Install a fresh copy and restore your bookmarks and extensions then test.

Another test you can do:

To rule out any problem with codecs or missing windows updates download a copy of Cyberfox Portable. It uses it's own separate profile and doesn't share it with Firfox unlike some other firefox variants.

See if you can play twitter videos with that.

Cyberfox 64bit Intel Optimized version (no java plugin)

https://cyberfox.8pecxstudios.com/cy...l-version-x64/

Cyberfox 32bit Intel Optimized version:

https://cyberfox.8pecxstudios.com/cy...l-version-x86/

Take your pick and download the Portable Zipped Archive. Extract the files and run the browser. Test twitter video. Also check the preferences mentioned earlier.

RE: Firefox.

It can screw up sometimes if you just keep applying available updates instead of clean installing it from time to time especially after the release of a version that has major upgrades.
