Firefox opens but only for a half a second. than the screen goes transparant
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.
Additional System Details
Every time Firefox opened
This started when...
- User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.4 (KHTML, like Gecko) Chrome/22.0.1229.94 Safari/537.4
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
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
