The extension performs reliably under most conditions. A compatibility issue has emerged with Google Gemini (gemini.google.com) when the platform activates an editable window—a new feature referred to as "Immersive" or "the Canvas." This window appears when prompting Gemini to generate draft text and triggers unexpected conflicts with the extension, rendering the tab unresponsive. Firefox identifies the extension as the source via an in-browser notification. The malfunction is intermittent, but once triggered, the problem recurs until the extension is disabled.

Actually works.

This add-on worked very well, however it has been made useless by stock features of firefox. Those stock features, however, I only found out about due to this add-on, and a review thread under it. I have spent one and a half hours trying to get this font i am writing in right now; thelorin; working on literally any writing thing anywhere. Thank you so so much, This means so much to me. <3 5 stars, lovely person, lovely people!

It replaces the default fonts on any website super nicely! It would be great if it was possible to change all the websites not only just the one, because I have to do it for each website manually, or replace specific fonts, like replace Roboto with something on my system. Maybe some kind of rules that we can edit using text that supports wildcards.
