Update from TB 78 > 91 results in *massive* memory leak and hangs in settings pages, crashing.

Hi, I've noticed my TB78 did not get a prompt to update for a very long time, but today it did prompt to update to TB91 when I checked Help > About. So I did the update and everything seemed fine, until I went into the Options pages and everything started hanging, it was impossible to click anything and the UI was not responding.

Eventually I looked in Process Explorer and saw the main Thunderbird.exe process memory use (private bytes) rising massively, to several GBs within the scope of seconds. It got to maybe 12-13GB and I started to worry about a system crash so I terminated it.

I tried creating a new profile and launching it, and it seems fine there but obviously no accounts set up. I also disabled all add-ons without it helping.

I have now restored TB78 + profiles from a backup and it works again.

So what can I do to figure out what's causing this massive memory leak and hang issue?

Also is there a simple way to migrate the old profile to the new one without having to create all accounts again? I have several Local Folders in MBX format I would need to migrate over as well, and the import "wizard" does not give the option to import from another TB profile (far as I can tell...)

Do you have a language pack (not dictionary) installed? They are known to cause TB 91 to hang when trying to open Preferences (Options in 78).

Thank you so much for your reply! :)

You were correct, it was a language pack installed (EN-UK). No idea why I even had it installed as TB is in EN-UK anyway. Maybe I got my default locale (Norwegian) when I first installed a long time ago, and decided to download the EN language pack as I prefer English for computer UIs.

Hopefully they can fix the hangs with language packs, it was a *nasty* memory leak there, I don't think I've ever seen a process go through the roof like that, 14GB of mem used in a couple of minutes... scary.

I've decided to do a clean profile from scratch anyway, and set up my accounts again, I think maybe better to start clean with such a big update.

I seem to have the same problem. Can some tell me how to remove the language pack?

Tools/Add-ons & Themes, language packs are in the Languages section. Dictionaries are separate and can be left as is.
