Since the update to Firefox Quantum, everything is very delayed including revealing what I type, scrolling down the pages. Impossible to play bubble shooter because it shoots the balls very delay and the reveal of the next ball takes forever. It is impossible to work on the firefox browser. I want to smash a hammer through it because I can type several words before I can see what I have typed. Now it is so slow I can type a whole sentence before I can see what I typed. PLEASE tell me how to go back to the version I had on Nov 13/17.
