So a lot of pages are loading really slow like minutes, like youtube and hot.ee mail service and a lot more. It started to happen when i updated to 20.0. Looked up some suggestions and found that about:config network.http.keep-alive to false help. And so i did it and it worked, but next time i opened firefox again it was slow loading again, but keep-alive is false still, disabled all not nessecary plugins and extensions and i dont seem to find a solution. Been a firefox user for a long time and dont want to change my browser.
