Hi, I have a small favour to ask. Every time this package updates the source value gets alterned and the versions gets hardcoded into it. I would suggest using $pkgver like this:
source=("https://archive.mozilla.org/pub/thunderbird/releases/${pkgver}/linux-x86_64/en-US/thunderbird-${pkgver}.tar.xz"
The reason I suggest this is the following. Every time I update packages I review PKGBUILD files from files that changed relavant fields. I filter out everything that only pumped a version and the hash changed. These packages should just pull the latest version from upstream. I do want to know if there are changes in the sources though and by hardcoding the version it always changes. I think this would also be of benefit to you since you only have to change the pkgver and recalculate hashes on update.

In the interest of correct spelling, I decided to integrate CircleCode's suggested change to fix hunspell and make it required.
Chances are this is opinionated, but I think if you can afford to install Thunderbird, you can also install hunspell.
%uchange not implemented, not sure if this is a good idea.
