Have used Firefox for many years on multiple computers. On the home desktop, anytime you need to CAP a letter, Scratchpad opens instead. Every single time! This is only having on this one computer, none of the others. I have completely uninstalled, cleaned and purged Firefox from this computer multiple times. I have run multiple virus checks. I have done the Firefox reset multiple upon multiple times. Yesterday I completely uninstalled every scrap related to Firefox I could find on the system, did a system clean to get rid of hidden and duplicate files, and with what I hoped was a clean system, reinstalled the latest version of FF. Same problem. WHY is Scratchpad coming up anytime I hit the Shift key? Somehow the developer tools and Scratchpad still show up and ultimately the problems start again.
