You're putting a lot of faith in uBlock Origin though. You have to grant it full permissions when you install it. Not at all saying that uBlock Origin is doing anything nefarious, but it certainly could.
But, somehow I trust a random dev that refuses to accept donations, even though my cheap ass would definitely donate to him, more than Microsoft, apple and (insert BigTech here)
Luckily uBlock Origin is open source and viewable on github, and isn't driven by greed. So I trust it more than Microsoft or any big tech company.
