🐞 Active features randomly working/not working

[Maltbrew]

Concise Description

Recently switched from Windows to Linux and getting to know the ins and outs. I'm using Zorin which is based on Ubuntu.

I also used this extension on Windows where every setting worked perfectly but it seems that it's almost random what does and doesn't work on Linux.

The first image shows my active features which do work. No complaints there, but the next screenshot:

The only thing that works consistently here is the subs being at 50% size.

Not pictured is "hide cards" not only does it not work, but since youtube added a hide buttons for their terrible cards, I can't hide them. It just says 'null' when I mouse over it.

I'm not really sure how to troubleshoot it.

Browser/s

Firefox

Other Browser:

Only FF on Windows where all active features worked.
