Firefox 33.0.3 Windows 7 Professional SP1 (64bit )

After my last update 30 33.0.3, Firefox now crashes from time to time with a completely unusable application window. Everything that can been seen in Firefox is very blurry (not black) and you can see the other application windows through the blur of the browser window. There is no web page content in the window. The menus are just black blocks and since I can't see the menus I have to shut the application down using “task manager”. When I kill the browser it comes back just fine. This has happened several times.

That should read :

"After my last update to 33.0.3"

Sorry about the misspelling. They need to add an edit feature.

Try to disable OMTC and leave hardware acceleration in Firefox enabled.

  • about:config page: layers.offmainthreadcomposition.enabled = false

You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.

You can try to disable hardware acceleration in Firefox.

  • Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"

You need to close and restart Firefox after toggling this setting.

You can check if there is an update for your graphics display driver.
