after some days stored passwords disappear, restart does not remember last used tabs

[Darko Veberic]

ubuntu 19.10, snap version 80.0.3987.163

normally, i keep the same chromium browser open for days. it gets closed only if an update requires a reboot.

as a certain pattern i have noticed that after several days (around 4 days in this particular case) chromium stops auto-filling the passwords. opening the settings, stored passwords shows an empty list. as an additional annoyance, restarting chromium results in not the most recent tabs but tabs that were open quite some time ago, i guess at the time when this bug actually occurs and the last tab state gets successfully stored.

is this a symptom of chromium losing the ability to write files after certain time?

This is a duplicate of bug #1616650. I suggest you enable the experimental flag that will prevent background refreshes while an app is running, see https://forum.snapcraft.io/t/wip-refresh-app-awareness/10736. Note that the current implementation will postpone an automated refresh for a maximum of 7 days, so this will only mitigate the problem, not completely solve it. But it should make the situation a bit more bearable, until a complete fix is available.
