Hi! :)
> you will have to hit the extension pinned to your toolbar to get it to begin functioning

in the current firefox you have to first allow extensions to run always.

you don't sound like giving this free public service less than 5 stars (what makes one greedy or believing in negative-motivation?)

Ads: the features hides all banners and tries to skip different version of the skip button it is just one in 200 features, not relevant, not unique and we might stop or separate it for legal clarity https://github.com/code-charity/youtube/issues/2751#issuecomment-2560581960 (read all by @improvedtube)

BTW currently a bug might disables a few more features unnecessarily and unfortunately firefox has not viewed the fix yet since December 29.
