thunderbird disable sideloading since version 78, see here:
Second change from top:

This practically means that thunderbird does not load addons (XPIs) from another place
than the users thunderbird-profile. The language packs in /usr/lib/extensions are
completely useless. To get a working lang pack, it must be downloaded by the user into
their thunderbird-profile.
The packages thunderbird-i18n-* could be deleted, IMHO. It's quite irritationg to
have non-working lang packs, took me quite some time to find the reason.

BTW, the URL in the thunderbird package is wrong, it's now,
thunderbird does not belong to mozilla any longer.

Additional info:
* package version(s)
* config and/or log files etc.
* link to upstream bug report, if any

Steps to reproduce:
This task depends upon

I will fix this issue shortly, the description here is also not true, its literally just disabled by default. While that's true for some context, its certainly not an issue for a linux desktop system to install packages from trusted sources like our distro repository to a location only writable with root. If on a multi user system an attacker manages to trick a user to install anything unknown and potentially malicious, its a lost case for any other user anyway and now having side loading won't solve anything.

I'm sure that language pack is no more necessary.
The language is set in "preferences" and a xpi file is download(see images).

Your pictures do not only show the interface to chose the language, but also to _install_ the languagepack :-) There are two possibilitys to install a language pack: The way you did it installs the pack into your home (~./thunderbird), but you formerly could also install it into the system for everybody. In linux you normally install the languagepack systemwide with a package of your distribution. Thunderbird now disabled this feature by default since version 78, but anthraxx wants to reenable it for arch so the languagepacks will work again. (I hope I got this right now...)

Config needs these two (from firefox PKGBUILD):
ac_add_options --with-unsigned-addon-scopes=app,system
ac_add_options --allow-addon-sideload

BTW, why are firefox and thunderbird PKGBUILDs completely different?
