Firefox '3 bar' menu not opening / not functional



I've tried the following but none of them have worked:



Starting in safe-mode.



Refreshing Firefox.



Using the default theme (I already was).



Disabling hardware acceleration.



Running Firefox from command-line and looking for errors (there were none).



Renaming / deleting ~/.mozilla and reopening Firefox. apt purge Firefox and reinstalling



Sigh! Does anyone have any other suggestions?



One posting mentioned Composting?
Settings for Window Rules / Window settings for Firefox -- Checked Block composting [ Force ] Yes... does not work!



Running Linux Mint 18.3 KDE -- up to date!



Does anyone have a fix for this????? Firefox... Sigh!
