flash player wont render

For a long time now flash content won't render properly when loaded in an inactive tab. I can see the background image of the site instead of the game. Some times a few strips of the actual flash content would be there but not always. This only happens on Firefox. I have tried multiple other browsers and had no such issues. Even IE doesn't have this problem... Why would I load flash content in inactive tab? I simply open the flash game on a new tab and continue doing something a bit more meaningful then waiting on the games loading time.

See if there are updates for your graphics drivers https://support.mozilla.org/en-US/kb/upgrade-graphics-drivers-use-hardware-acceleration


Make sure you are not blocking content.

Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?


One issue that seems more common lately is Firefox's Tracking Protection feature. When it is blocking content in a page, a shield icon will appear at the left end of the address bar next to the padlock icon. This article has more info on managing this feature: Tracking Protection {web link}

My graphics are up to date, sadly this happens on all computers in my home. And when I reported this issue to Flash support they where able to re-create it as well. The sites don't usually have tracking I have not seen this shield icon on the places I have issues with. The problems started ever since I updated Flash to version 26. Been hoping it will fix itself ever since but no such luck...

It seems something just broke between firefox and flash when it comes to rendering in an inactive tab. If I refresh and stay on the same tab with the issue it loads just fine.
