Firefox has been fine for me, tons of tabs yet doesn't use much memory. It isn't slow, seems the same as any other browser.
The list of places mentioned in the article I would never go to anyways so I can't compare.
Funny how the list is the shittiest places on the internet, makes you wonder what those sites are actually doing to seem to slow a browser....
Firefox. Fast and light as usual. I see people say it isn't and I just don't get it.
Linux, compared to chromium its the same speed, but with better features of course.
