Blocktube. Simple and advanced blocking of videos on youtube. Worth getting. Also stops youtube from auto pasuing after having watched a while.

Consent-o-matic. Set your preferences and it will automatically click those specific preferences when you visit a website, where it recognizes the cookie accept popup. No more need to click accept all, to move on. (It does not know all types of cookie pop ups, but it knoes the ones used by a large chunk of websites)

Imagus. Mouse over an image and this extension will attempt to show it (on your mouse location) in larger size. This works great for various things. News articles, social media etc. It can even do it for video and gifs. It can be annoying in some cases but… ive gotten used to it. I used to use it on reddit. Just mouse over the posts titles and the pic would pop up. And as said before, super nice for articles and photo albums etc
