Ublock Origin is an obvious one, but I also can’t stand not having Foxy Gestures anymore. It adds customizable mouse gestures, so you can set it up to have easy swipes to go back a page, reload a page, close a tab, etc, and it feels wonderful and smooth to use compared to just using the traditional buttons to do everything. Honestly it’s kinda wild to me that this isn’t more popular now that people are so used to phone gestures. It’s good for the same reasons!
Ublock + Sponsorblock are a killer combo I couldn’t use the internet without. I also use keepa to see amazon price history.
If you already use Ublock, isnt another blocking extension (Sponsorblock) kind of meaningless?
