This extension is completely useless. I set the page zoom to 90% in the extension for a specific page and saved it as a rule. When I close the page and reopen it, the page zoom is not set to 90% because you can see this when you check the page zoom in the Firefox hamburger menu.

domain only

Didn't find a way to set per specific page, but it's only available per site

I wish I had a backup restore setting

Very great extension,it works on Android. Thank you very much.

it zooms in a wired way, still the idea is <3 :D
