Firefox issues cleared by uninstall and re-install Firefox

Hi community,
Mac OS Monterey Blocs 4.52
I was was going in circles with Firefox issues on a broad range of our sites created in Blocs, problems with local font replacement / hamburger + concertina’s not functioning – all good on Safari and Chrome.
It was only with a new install of Firefox 104.0.1 onto one of the testing devices that it cleared up. So we uninstalled and re-installed new download of Firefox (even tho we had the current version) Not sure if it has been the multifarious OS updates or what…but it worked.
hope this helps someone from spending hours searching for solutions.


Hmm… non-standard solution, but thanks for the info, we’ll try it.
