I found out its on a list of extensions that gather and sell your data.
Works well, but being part of a bot net is a deal breaker.

Don't listen to that barnikjelleren below me. He read the web-scraping botnet extensions list but didn't even bother to double-check if that extension was this extension or not (of courses it isn't)

this extension is confirmed to to scrape your data on websites to be used for advertising

Good but can be very buggy sometimes.

Scroll lag

Can finally get Excel in dark mode. This extension is a MUST-HAVE!

This extension makes the web unbrowsable. Have been trying on and off for a couple years, but the amount it slows down the browser is insane, and even sometimes the entire browser freezes up. Problem solved by uninstalling.

Wow

Awesome extension, extremely helpful for browsing at night!
