I used to really like Dark Reader, until it seemingly ruined firefox for me. Now, I have some websites that will only work if I enable Dark Reader, as the text often is permanently white. This is a problem that has stayed even after I disabled Dark Reader. The only thing that works is completely reinstalling firefox. Some websites just don't look as good in dark mode, so not having the option to turn it off sucks. It also started slowing down my browser like crazy, so it has its fair share of issues.
