Does not work in firefox 64.4.0

stops tabs from loading as intended
but shows numbers (61662...) instead of the page title and icon on the tab after reload

Noticed after I installed this that youtube would reload and then not load the video itself.. Now even removing this it still does that. Now I can't watch any videos. I have also noticed problems similar on other sites when I installed this. Not happy. Now have to reinstall Firefox .

Gives every tab an ID name instead. This makes handling unloaded tabs impossible since all tabs have the same ID name...
