Hmm. Not sure what I'm looking at here. I tried clicking stuff. The first three buttons I saw (traffic light) did nothing. The fourth one made the rest of them go away with no obvious way to get them back? I don't have any video or images I want to share with a third party without understanding the consequences, and I'm sure as heck not installing an extension so... I guess we're done here?
It's not that I'll never install an extension (I currently use two, one ad blocker and one to filter Pinterest out of search results), but it's certainly not something I'm going to do casually.
