As said before me, this is an indispensable add-on. My headaches from squinting so much make it difficult for me to use Firefox, and has caused me to nearly abandon Thunderbird since last week, when Theme Font size Changer suddenly quit working.

I will also join the chorus to plead for this add-on to once more be available for Firefox Quantum.
