This extension worked with LastPrice and Paneco, sometimes it works with AliExpress (50/50), it doesn't work at all with ASOS and Booking. Found it annoying with all these multiple logins and tabs that should be opened after you click on the extension. But in theory, it must be great and super-useful.
