I was the same. Reading all these Lemmy posts thinking “with my Firefox and uBlock I’m still cruising YouTube ad free” until last night when I finally saw this. Refreshing the filter list on uBlock does the trick but it sucks that it requires closing all your tabs. There were so many things I queued up that I was never going to get to, now I don’t even know what they were!

I could’ve bookmarked the tabs into a single tab folder and then restored them once I refreshed? Yeah I don’t care that much, but I do do that on occasion.
