dimden

Works fine for me 

Yeah seems like it only doesn't work on Firefox, idk why, I tried few possible fixes but none worked

Can't you just zoom in with your browser? That would be basically same as increasing font of everything. Also you can install Chirp font locally and set it in settings...

I don't have a Mac so I can't do this myself...

It's impossible to compact everything extension does into a userscript

Added! 

Done

Uninstall, login, install again

You can't use this extension without an account

Fixed
