Comment 25 for bug 1945697

Quick update after a few days of using

`$ sudo snap set core experimental.refresh-app-awareness=true`

No more crashes (same behavior as @mruffell wrote above), which is great!

Few annoying things remaining from what I could witness as a user:

1. I thought that closing and restarting Firefox would take care of updating the snap. Nope, turns out I had to manually do a `sudo snap refresh`
2. With Chromium, I had to manually kill all chromium processes before `sudo snap refresh` would work because, somehow, there was still snap chromium processes running after closing Chromium.
