Does not work on Mozilla Protected pages, even following instructions on the github. Whoever made the decision at Mozilla to both disallow this to work on their pages AND not include dark themes on their websites doesn't deserve eyes. I hope you go blind.

One of these tools that just works so well you forget it's there

Sendo sincero eu achei bom, o único problema seria que algumas vezes ele dificulta a minha visão mesmo eu modificando para melhor visibilidade.

Unusable. Brings PC to a crawl. Keep getting notifications that this addon is to blame. Have Uninstalled. Love dark theme, but not worth the huge hit to performance. Luckily more sites are including dark themes, hopefully making this addon obsolete.

pls add export and import feature for adding site list
