It does not matter what I am doing the scrolling lags and the writing some time the mouse does not work always delay ? Help Please

hi, could you go to the firefox ''menu ≡ > help ? > troubleshooting information'', copy the contents of that page and paste them here into a reply on the forum (or if it's to long through a site like [https://pastebin.mozilla.org/] and provide the link here)? this might give us a clue what is going on. thank you!
