Unfortunately much as I love this add-on its not working on Firefox Nightly as of today.

The add-on is not bad, but currently it does not memorize the setting per-website, at least it seems to mess up when switching to another Firefox window, so it works application-wide. In my dark theme its icon is unrecognizable when toggled.

I love how simple it is. I use the whitelist mode to enforce browser fonts for only a few sites.

However, I noticed what seems to be a bug: when a tab in one window triggers the extension, all other windows change to browser fonts as well, regardless of the URLs in those windows/tabs.

Great!
But I would like to have direct access to the list of individual sites inside this extension, to figure out why dev.azure.com (I want site fonts) and *.microsoft.com (I want my fonts) are considered as the same site with common mode, and find a way to fix this.

P.S. Rebooted several times (long story), and this feature seems working properly now. Thank you! Will know that I can post issues to your repository, in case of bugs. I will edit this review in a few days when it becomes obsolete.

Enforce Browser Fonts works well, allowing a quick toggle between default website fonts and monospaced fonts. Would be useful if the Add-on could be configured to engage depending on a user configured white-list.

It works!

Ça marche ! Je mets Arial comme police par défaut sur tous les sites mais certains ne s'affichent pas correctement, avec cette extension je peux désactiver sur les sites où ça dysfonctionne, merci !

Could you change the color of the icon when it is activated? My theme is black and we can't see the icon, put it in gray ?

There is no website list management feature.

Very interesting. Thanks Jayesh !

does what it says on the tin

caveat is that this will increase entropy (ability to fingerprint the browser), so just be aware

looking forward to the implementation of a list of sites where the ext. is disabled/enabled

pretty good but needs some work, some of which is on the developers todo list

would be nice if it switched faster when changing tabs

i bloody hate when websites override MY default font choices with their goofy fonts and this add-on is a great way to combat that

Works! on macOS Mojave, including option-comma shortcut.

My implementation may be to blame, but this doesn't appear to work on Firefox 56.0.2. Developer already notes Firefox doesn't support the API yet, so this review is just to provide information.

Well implemented and quite useful, thanks!
