shortcuts with the extension is not working for me

Unfortunately, it sometimes creates noticeable performance problems

Slows some things down like the initial load of gmail. Artifacts on some things. Ex. the banners at the top of testout.com after logging in.

Why doesn't Dark Reader work in my firefox? All the websites still have white background. I check the firefox settings. Dark reader is enabled.

la extension es casi perfecta, pero es muy pesada

Impressive addon, works pretty well and on a lot of different websites and webapps. The settings and configuration options in the popup are pretty hard to understand though, even after reading the documentation page it's not 100% clear for me.

Almost perfect but slows down some websites

Good but I don't like how the extension changes the theme of the browser. Is there any way to just change the webpage colors without affecting the theme?? If you are the developer then please reply.

Very good. Just need a dark background in about:blank and about:newtab. I have a white page during 1 second before a page is loaded.
