Spellchecking only available for English in Tor Browser 9

Nothing in Tor’s Trac about this.

Note that the Thunderbird maintainer in Debian wrote:

One more important change is the impossibility to use system wide
installed dictionaries. At least I haven’t found a way to still use
them. If this can’t get changed all the recommends on the dictionary
packages will get useless. If someone can contribute something here to
solve this I’m happy to take this help!
