It used to work but doesn't anymore, earlier if i tried to activate the extension from the context menu it just froze entire tab indefinitely, now i cant even enable it anymore after i had disabled it because enabling it just makes my cpu run at 100%. When enabling the extension firefox profiler says definer is constantly running some reevaluateRulesForTabs javascript for the longest time and thats causing all the jank

It's using a lot of CPU even when it's idle. Approximately around 60% CPU usage increases when I activate this addon.
