why does firefox display websites incorrectly after sleep mode?
after my laptop lid is closed and generally after the laptop goes to sleep mode firefox displays all websites incorrectly. Sometimes sites are white over all, sometimes there are glitches and very often the tab bar is displayed a second time in the content area. Also the context menu does not show up then. this behavior is very annoying, I think I need to change to another browser. It has been happening since 3 or 4 weeks.. (and can be reproduced everytime I close and then open up again the lid of my laptop.)

You can try to disable hardware acceleration in Firefox.
- Options/Preferences -> General: Performance
remove checkmark: [ ] "Use recommended performance settings"
"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 and check for hardware acceleration related issues.
