I wanted to like this extension, tried it for several weeks. **Constant** tab crashes and memory leaks from overly aggressive CSS injections. As long as Dark Reader has been around, I just don't understand how this level of extension instability is even possible. GitHub is wholesale unnavigable due to tab crashes.

I ended up settling with manual changes to my browser's color/high contrast settings to force a global override on site colors. This at least works without ramping memory usage or crashing tabs. While it's a somewhat crude solution, that solution is indeed more effective and stable than using a third-party extension.
