Firefox menu button does not work

[Sergio Callegari]

In the last few days:

Many firefox extensions stopped working (e.g., feedbro, ublock.origin). For both the buttons do nothing.

Trying to uninistall and re-install them results in the progress bar for the extension download getting updated but the extension never getting installed.

Trying to erase the firefox profile results in a "new start" screen for firefox at restart, but the menu button does not work at all.

Trying to reinstall firefox does not change the above.

Found issue to likely be in mesa. Sorry for the noise.
