I stopped using Firefox as my main browser back in 2013 when they disabled the option of selective javascript policy.
I switched to chrome, until it caused me problems.
Then I switched to Opera, until it became extremely rogue and destructive to my PC in terms of memory leaks, memory consumption and CPU time consumption.
Now I use a combination of Blisk (as my main browser), Chrome (due to its webpage translation capability) and Firefox (only for downloading videos through its add-ons downloadhelper and Flashgot)
