Aaaand it’s finally available as a direct download for Thunderbird (and FF / FF ESR up to 56.x) – use the addon page in your TB/FF or have a look here: https://addons.mozilla.org/en-GB/firefox/addon/theme-font-size-changer-fixed/
That only took 13 DAYS to approve, I’m impressed. Go Mozilla, you guys are awesome! (I kept one of the keywords for that fuckup, tyvm)
Well, everybody wants them, but there are no spares left and they die left right and center...
