I haven't tried it in firefox, I'll definitely give it a look. Using it in chrome however, the performance feels the same as the hacky electron wrapped version. I notice it the most when switching between two heavy pages or trying to get to the bottom of a page I have 50+ pictures saved to. But it's useful for me to still have it register as a separate application in case I ever need to kill chrome for some reason. Or for organizing it across my different desktops.
