FF7 / Windown 7 Taskbar floats above fullscreen Flash video


Since upgading to FF7, the Windows 7 taksbar floats above fullscreen Flash video.

I've updated to FF 7.01, updated the Flash player to, disabled all other plugins and extensions, and the problem persists.

For the moment, I have to autohide the taksbar in Windows when watching fullscreen video.

Happens on YouTube and Vimeo and all other video sites I've tested.

Additional System Details

Installed Plug-ins

  • Shockwave Flash 10.3 r183


  • User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:7.0.1) Gecko/20100101 Firefox/7.0.1

Found a fix. It was something to do with my DPI settings in Windows.

Right click on your Firefox icon (not the one in your task bar), if it's not on your desktop, find it in the Mozilla Firefox program folder.

After right clicking, select Properties, then the Compatibility tab, then check the box that says Disable display scaling on high DPI settings.

That's it. I'm now back to using 200% DPI and have no problems with fullscreen videos. What a pain in the ass!

Changing this setting does not work with FF 9. I followed your instructions exactly, and when they failed to fix the problem I also tried the same setting on the plugin-container executable. Both failed to fix the taskbar floating over the fullscreen video.

Windows 7 x64, FF 9.0.1
