can confirm that memory leaks (eats all free memory - up to 50gb ram for 3h), high cpu usage on v.5. Also pages do not open in new tabs the first time "Modify existing content security policy"=off, "Never remember history"=off, private=off
Please report an issue at GitHub and explain what you're doing while this happens. I double checked the code, used Firefox many hours and can't reproduce. Thanks.
