Used to be good, but UI is outdated and doesn't work with the dark theme of Firefox

was working fine in the past - but since 2 weeks it ignores my setting. I set the zoom to 150%, open a new website, firefox shows the zoomlevel also as 150% - but it is in reality only 100%. If i go in "fixed zoom" to +- it sets the website to 145 or 155%. If i to the same in firefox, it jumps from 150% to 100% and then to 110 or 90%.
Maybe this bug is related to firefox - but without the addon firefox works as aspected (i have to set every *** website manually...)
Please fix the bug so that every opened website is really at the zoom level that is set globally.

Lo zoom deve sempre essere reimpostato, non tiene lo zoom su tutte le pagine! Voi che date 5 stelle, sapete cos'è lo zoom???

I had hopes for this, Mozilla seemingly killed the ability to save zoom levels since FF60, but there are too many bugs in this add-on.

I have to constantly reset every time I leave a page. As an example I use a home page that is an RSS reader, it becomes a mess, the main page reverts to some setting that I never used, the links within are a complete mess, they just randomly choose a zoom level.

There is no way to add custom settings, the Manage Rules setting is greyed out, nothing can be saved.

Too bad.

Update: I have checked "enable" many times both under options in my add-ons list and using the icon on the toolbar (or whatever it's now called), it doesn't matter, it won't save.

I will keep monitoring your updates and try them out periodically. I don't normally write this much about an add-on, but I do think you're on the right track and I need something like this that fixes the Mozilla mess on something as simple as zoom.
