Latest release Thunderbird 91.0.3 x64 hangs when entering Preferences. It is very slow scrolling after that and total hang on in a few seconds.

OS is Win 10 Pro x64 21H1.

Also I cannot find the way how to open Config Editor - there is no appropriate tab in Preferences (as far as I see before hang on).

This is causing your problem

You installed a russian language build, and installed the russian language pack on top if it.

You don't need the language pack. And on 9/6 you wrote..

> In safe mode Preferences opens OK

This is a strong clue that something other than Thunderbird was causing the problem.

Damn I completely forgot about this obsolete langpack. Thank you. At least someone is competent enough to help.

I had the same problem (with the English GB language pack), and eventually figured it out. https://support.mozilla.org/en-US/questions/1349852#answer-1456113

However I'd like to add that the language pack was already installed prior to upgrading. Would it be reasonable for the updater to check for a 'redundant' language pack? It is also clear that during testing, Firefox allowed me to install the troublesome language pack without any warnings.

I don't know how difficult it would be to auto-remove or disable, but at least warning the user might be a good idea. I recognize that in some ways this is a bit of an "own goal" problem
