I go on youtube, and the videos work. But when I go on tumblr, the music files or videos other than ones uploaded on youtube, won't even show up. I tried reinstalling firefox, flash player, and adobe programs. I even shut off my computer and turned it back on, but still nothing. It worked a few days ago, but now it doesn't. Someone please help.

Most videos on the web use the Flash Player (Shockwave Flash plugin). In case there is a conflict, could you try temporarily disabling your DivX plugins here:

orange Firefox button or classic Tools menu > Add-ons > Plugins category


A standard diagnostic for interference by extensions or custom settings is to test the problem sites in Firefox's Safe Mode.

First, I recommend backing up your Firefox settings in case something goes wrong. See Back up and restore information in Firefox profiles. (You can copy your entire Firefox profile folder somewhere outside of the Mozilla folder.)

Next, restart Firefox in Firefox's Safe Mode (Diagnose Firefox issues using Troubleshoot Mode) using

Help > Restart with Add-ons Disabled

In the Safe Mode dialog, do not check any boxes, just click "Continue in Safe Mode." Flash should still be enabled.

If you can see media where you couldn't before, that would point to one of your add-ons or custom settings as the problem.

Any change?

Are you sure Flash is correctly installed and working? When Youtube detect there's no Flash support on your computer, it may enable if possible a HTML5 player compatible with your browser. If there's no way to do so, it would alert you Flash is not installed or working well.

Maybe videos work on YouTube because it enables HTML5, which doesn't require any plug-in at all, but Tumblr requires Flash for playback.
