Some of the things that have already been mentioned are true also for me, especially around permissions and assumptions about my system's setup. However what really did it for me was when Firefox stopped recognizing my keyboard after a snap refresh. It's just as if no input device was there for FF anymore. I found reports of the issue, but no solution. In the end I installed from a DEB repository and went through the shenanigans to prevent snap from reinstalling it.

It is old! The filestamp is from 2008, but I'm afraid I have no further information.

Τα προσωπικά και η βοήθεια που προσέφεραν άγνωστοι προς αγνώστους. Κατά καιρούς έβλεπα απελπισία και μηνύματα συμπαράστασης. Ερωτήσεις σε απλά ή σύνθετα θέματα και απαντήσεις. Δεν ήταν πάντα ακριβείς ή σοβαρές, αλλά νομίζω είχαν ένα θετικό αντίκτυπο συνολικά.
