Steps to reproduce:

I use thunderbird (+ enigmail & lighning) on ubuntu (first 18 LTS, now 20 LTS)
It's nearly never restarted.
There's two usable profile on it (archive and current).

Of one of the profile (current) :
After a few weeks, sometimes months, memory consumption reach a crazy amount (more than 16 Gb)

Safe mode doesn't change anything, the other profile does not have this problem


Actual results:

After reaching too much memory (mostly all of the RAM), thunderbird begins to malfunction : crash, freeze, some of the time refusing to start at all.

This issue can be solved by deleting panacea.dat (around 86Mo currently), but comes back again a few time later (weeks, months ...).

This might link this to following bug 1084276


Expected results:

Normal usage ;)
