Do you have any Firefox themes installed which might be modifying the appearance of the back button?

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.
- Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance
- Do NOT click the Reset button on the Safe Mode start window

You can try to disable OMTC and leave hardware acceleration in Firefox enabled.

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.
