Since Firefox 64 - spotify (website) will cause memory leak ( actually the tab eats all my system memory up to 16gb ) and i need to close the Tab, after an advert gets played. The Song Adverts are getting Blocked but this will end in a huge memory leak. So i need to add the spotify website to whitelist in ublock. Hopeful this gets fixed :)

Great ad and annoying content blocker -- Works like a charm!

Love it :)
