Firefox Titlebar disapearing randomly - Ubuntu 18.04
I am using Firefox in Ubuntu 18.04 and Title bar disappears randomly. Also while Title bar is missing Firefox window never comes to top if under another window. Customize > Title Bar Checkbox == ON.
I was trying to use F11 with no success.
Workarounds that works:
- Grab one of tabs and move outside of existing window (title bar restored), then other tabs moved to such window are OK. - Go to Customize > Title Bar checkbox (is ON) / deactivate and activate again. After "checkbox restart" Title Bar is restored back.
All SW is up to date. Any clue? Any hints please?
