after searching for months i finally found the culprit, it was this damn addon. it makes firefox so slow that gmail or youtbe hardly work anymore, many other sites don't even load. absolutely NOT recommended if you use firefox.

Biggest dark reader program and still can't detect dark mode even on the most popular websites, while simultaneously breaking them.
At the same time, they beg for money at every corner in their UI and website, blaming their users for not paying in their blogposts, and acting like it's the user's fault when they get review bombed. Think for a second, does a universally loved extension get review bombed like that? No. Dark Reader, while the best, still has huge issues. Mainly the people behind it. They only do it for the money.

Oh, and if all that wasn't enough, it absolutely kills the browser performance, both in real usage and in benchmarks. In most benchmarks it only reaches 50% of the speed compared to having Dark Reader off.. just use something else

The "news" pop ups on the bottom of the addon window are a completely pointless and stupid idea that distract me from managing this addon effectively. I am sick of these out of touch software developers that think the UI of their software is the perfect channel to push ads, news, or "HEY LOOK, WHATS NEW?" spam in your face.

Breaks websites, often get an access denied message & disabling doesn't help, the add on has to be removed altogether to rectify the problem.

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
