Firefox 38.0.5 - Windows XP - I can't play Vimeo videos, and when I go on to Youtube the screen says "a plugin is required" for a second, then the video starts.

I discovered today that Firefox doesn't play Vimeo videos any more. It plays Youtube, though the screen says "a plugin is required" before it actually finds one and begins playing. Plugin Container no longer appears in the Task manager.

System: Windows XP

Firefox Version: 38.0.5

I understand that vimea requires a plugin in order to watch videos. It may be trying to detect a video player like flash or realplayer. Use plugins to play audio, video, games and more

If the plugin container is missing you can use a stub installer from the page you originally downloaded Firefox to repair your current installation.

Note that some pages (YouTube) can use an HTML5 media player and in that case you won't see the plugin-container process.

Your system details list doesn't show that the Shockwave Flash plugin is installed and enabled.

  • Firefox/Tools > Add-ons > Plugins

You can find links of the latest Shockwave Flash player for Firefox on this page:

You can verify on the Adobe Flash Players Test Page that the Flash plugin is working and which version you have.
