No Mozilla appmenu? (Firefox / Thunderbird)

Created by: ASAPHAANING

I followed these instructions of https://www.linux.org.ru/forum/desktop/11473563 and now I have a working appmenu- sort of.

Firefox/Thunderbird used to work and other apps didnt, now it's reversed.

UPDATE: I've tried running export UBUNTU_MENUPROXY=0 firefox and inserting UBUNTU_MENUPROXY=0 firefox into the desktop file but it doesnt seem to have any effect.
