Makes all the thumbnail images on amazon.com dark. It just darkens the whole website, as if I were wearing sunglasses and turned the brightness to minimum. That's not what I want out of dark mode.

slow down Firefox. Can't change per website, only global.

Can't turn on per website. Only turn off.

Не совету. эту программу, она тормозит работу браузера, и многие сайты попросту не открываются из за нее, снес ее и ставить не советую, так многие сайты у меня не работали на гугл хром и Firefox

Slows down Firefox too much for no reason.

Very slow and isn't useful, hang browser. Need Optimization and refactoring! Performance is important!

Breaks half of all webpages and causes tons of lag

makes youtube video completely dark, same with other video pages, unable to select to only apply to specific pages

A great addon in theory but in practice it makes pages load 4-5x slower than normal firefox, or not load at all meaning you need to keep refreshing until the page works again. This extension would be a 5 if it didn't have any performance impact, however in its current state I would not recommend it.

This thing made my lapup sounds like AC outdoor unit when trying to adjust brightness

WTF? Didn't work

I removed hours after installing as it made my CPU utilisation jump from 7% to 97% all by itself. It has good features, but it is not worth it if my PC sounds like it is about to explode from it.

Suddenly installed when mozilla does its clusterfuck install when reinstalling mozilla. Dunno why it was installed, but it can fuck right off.

New update unfortunately breaks cookie popups leaving me unable to interact with any website that gives one. Half the time the cookie popup doesn't display properly, and the other half I can't click on anything on the page (including to accept/deny cookies). I've sadly uninstalled it for now.
