Ondersteuningsforum voor Firefox

I'm trying to watch videos in Firefox. Youtube works but Xvideos does not. Firefox pops up a window asking me:

>> "Opening xvideos"."com ###.mp4". >> which is: MP4 Video (16.4MB) >> from https://cdn77-vid.xvideos-cdn"."com >> >> What should Firefox do with this file?

My only choice is: Open with Windows Media Player x86 (default)

suggestions?

I'm running Windows 7 Firefox 76.0.1

Thanks!!!!

Hello, I am having a problem going to the daily mail us site. A pop up appears asking me if i want to continue to the us or uk home i select us go there and the pop up re-appears. I've tried all the usual culprits and it seems to work fine in chrome. thks

I'm using Firefox 76 packaged with fedora 30 but it wont display a video (weirdly youtube does work). I'm getting the message: "this content requires adobe flash or HTML5 video support..." I don't want to install flash because I've seen some content somewhere about security concerns. I looked for an extension or add-on but none of them seem to be Mozilla approved and most of them don't seem to address this issue anyway. I can't find a setting to fix this in Firefox. I've seen an archived thread about this problem suggesting maybe some linux library issue, but it contained no solution. Maybe I'm missing something fundamental but it's 2021 now and I'd like my Firefox to support a bit of video here and there other than youtube. Has anyone got a solution?
