Dark Reader used to work so well but lately it's been breaking on multiple websites. Twitch is overlaid with a gray box and text is often set to the same color as the background. Additionally I've had issues with high CPU usage on certain websites. FF 124.0.1 on Linux.

It seemed very good at first. Loved the sepia effect on several sites. Then, it broke down on several sites - I had to turn it off then on in order to read some texts. Not to mention it slowed down the pages.

It works well until a week ago. Several webpage looks broken when dark reader activate. Currently using on mobile firefox
