Firefox worked great till I closed a movie on YouTube. Then the screen went transparent and only the 3 buttons on the right top of the screen were shown. I have restarted my pc, re-installed firefox, but the problem remains. When I start the program, It shows the correct browser for only a flash before the screen becomes transparent and nothing can be done. No menu bar, no orange button, just the three close buttons on the right.

hello C_Bronoord, can you try launching firefox in safe mode by pressing the shift key while it is starting and see if the issue is occurring there too? maybe a theme or hardware acceleration is interfering here...

if safemode is working, you can try disabling hardware acceleration in firefox > options > advanced > general and or disable addons that might cause the problem. it also would be interesting which graphics hardware (adapter description, driver date & driver version) you are using - you can access this information in firefox > help > troubleshooting information towards the bottom of that page... thank you

Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems

edit: from another user we found out that this might be related to malware, could you see if you have the same addons installed, remove/disable them & run a in-depth scan of your system with security software - see https://support.mozilla.org/en-US/questions/940393#answer-377118
