For what it is worth, this problem is now back -- very soon need the Thunderbird 91.3 installed into Ubuntu as 78.x is about at EOL. Debian have already prepared their packages in Sid (91.2.1 and 91.3.x no doubt shortly to follow). They also offer firefox-esr and do similar work with that packaging.
I recall there was a suggestion/bug/discussion about sharing resources on ESR for at least Thunderbird, to save duplicate resources, not sure where that got to. I am writing to this bug just to notify likely-relevant people, but if this isn't happening and needs a bug-report, please start a new bug report and link it to this bug, as this has got long and complex already!.
