I've used Dark Reader for YEARS but I'm finally throwing in the towel. At least on Firefox, this extension will lag your browser to death. I spent a whole week trying to trial and error what extensions were causing such huge memory usage issues and constantly causing sites to lag. I figured it was something like ublock, canvas blocker, or chrome mask. Nope. Everything lead back to Dark Reader.

This extension has helped with my eye-strain issues so much. I seriously hate to get rid of it but I can no longer look over the performance issues. Please, figure out a way to make this extension lighter or at least a stripped back version. I would love to come back and write a nicer review. For now, I will be using Stylus and simply grabbing user dark themes where I can.

Rating 5 stars because this feature is invaluable, and I've been happy to donate to the extension's development. This extension made giant strides since a few years ago; I almost don't need to disable it to unbreak sites. The performance could have been better, though.

While it works beautifully, it has a super high impact on the performance of a browser, whether is it active on the website or not :-/

love this thank you for 12 years.
