Finally I can change a few sites that use material design fonts with stupid arrows and symbols without changing my global settings to prevent the horrible antialiased fonts most use from ruining my eyesight! Thank you sir!

Firefox 78: I see only "Loading", when I click the ReFont button. Cannot change font. :-(

It does not work for android firefox.

The fonts in the library are not sorted alphabetically.

ReFont:
Amazing to transform game server pages, that include config files: Now I can edit code/script with monospace font!

TUTORIAL?
1) Click 3 times the bar icon to refresh the addon; If it doesn't work = keeps "loading", its because that site is forcing its own font types, ex: jsonlint dot com / umod dot org (developer should explain this to avoid 1 stars, not his fault)
To change this behavior, go to Firefox "Options" > "Fonts and Colors" > "Advanced" > On the popup "Fonts", uncheck "Allow pages to choose their own fonts, instead of your selections above". That is it, now it will work. But remember that some sites like Firefox/Mozilla will still block changes.

1) Ok, lets start again: Click 3 times the bar icon to refresh the addon (turn on, off, on)

2) Click the greyed out option "Show more"

3) Choose "Site Font" to change ALL pages on that site domain OR "Page Font" on only remember changing the current page. Like Tod Howard said, it just works!

It applies one choosen font to EVERY Website, i love it!

works great (added Lexend fonts) but does not apply font to iframe content. Please include this in the next revision.

People seem to be complaining about the 'loading' bug. A simple way to fix it seems to be just to close and re-open the add-on thing, that seems to work for me.

Fix the addon soon, plz

Doesn't work, stuck on "Loading"

Doesn't work, just gets stuck on Loading

Not working for me. It just says "Loading" but never loads. Not sure why. I don't see a way to offer specific feedback but I enjoyed this extension in the past.

Rather good but I haven't worked out how to use local, non-Google fonts for Android.

This extension is great and it allows us to choose how we want to view the web. It works perfectly with Firefox's capability to customise the cleartype settings. However, the load time is quite inconsistent with the latest Firefox. I wonder if there will be any update soon to address the load time issue? Thanks again for this great add-on.

What a fantastic addon thank you :)

How does one add a font from one's computer? I use OpenDyslexic and it is not on the native list. Also, infinite load time.

Great but seems to have broken.

It just doesnt seem to work. Just keeps saying Loading but nothing happens. Have reinstalled, granted all permissions but nothing works.
