And a few hours after I wrote the review Mozilla allowed for the Jan 30th update (v2.0.131.1) to go through and it actually seems to be working again. Thanks, boss.

---------------------------------------------------------------------------------------------
I am seriously lost at this point and have no idea what is happening anymore. Been using this add-on for a few years now without any issues, but something went seriously wrong a few days ago.

Are there any dependencies to other add-ons?(if that is even a thing?)
Once I removed/disabled ViolentMonkey (wasn't running any scripts for the past 6+ months or anything youtube related to begin with) most of the functionality just stopped working or is malfunctioning and re-enabling the add-on brings the functionality back.

Theme function just keeps reverting to "Firefox Alpenglow dark" theme regardless of whether I switch to a different theme or I uncheck the "Dark Theme" option all together.

Any Video Player options just don't work. Full-stop.

Any attempt to revert to an older version(2.0.130.1) or reinstall the latest version(2.0.131) of the add-on does not seem to help.

Going to keep the review at 5 stars because it is most likely an issue that affects me only and I seriously love this add-on.
