Videos, like mp4 Vines, won't play in Firefox. Same with the media files like podcasts in rss feeds. All used to work fine. This is an intermittent problem with Firefox ( might be due to updates ) but it doesn't happen with IE or Chrome

If i uninstall VLC player or disable the VLC plugin, nothing happens If i have those installed but the VLC plugin is set to " Never activate ", i can right click on the video image, click " Play " and it opens in VLC player and works perfectly. If i have the plugin set to " always activate " then i see a black square and the message " the video can't be played because the file is corrupt "

Windows 8.1, Firefox 35.

This is an issue with Firefox and needs to be resolved.

Firefox "unable to connect" ONLY to vine.co and linked vine videos from other sites

For some reason, starting about a couple of days ago, Firefox will NOT load the site vine.co - it displays the "Unable to Connect" page (see linked image) and I can't think of anything to do. All other video players work - on Youtube and Facebook and it's very strange that I'm not able to access only this entire site. Also, on sites such as Twitter and Tumblr, I am not able to access the vine videos (that have been linked, I assume, from vine.co) - it will just show a square on the webpage where the vine video player should be but it just has the "unable to connect" image instead. I have Ubuntu, all updated, and Firefox is updated as well to the best of my knowledge. Does anyone know how to solve this problem?

I'm not sure exactly when this started happening, whether it was related to a new version of Firefox or not. But at some point embedded Vine videos on other sites would no longer play. For a time I could go to the video itself on vine.co and that would work -- but now nothing plays there either.

I've done everything I can to research this. Turned off all add-ons, used that about.config trick that's frequently recommended for this problem, turned off plugins, added new plugins, refreshed Firefox, used a new profile -- nothing seems to make a difference. The only thing I haven't done yet is uninstalled/reinstalled Firefox completely.

Any advice, please? I stopped using Chrome because it was such a memory hog, and would prefer not to go back again.
