they keyboard shortcuts have somehow been changed so that when i press control it zooms out and when i press shift it goes back to the prior page
out of nowhere, firefox started zooming out whenever i press ctrl and going to the prior page whenever i press shift. i don't understand how this happened and i can't figure out how to fix it.

Start Firefox in Safe Mode by holding down the <Shift> (Mac=Options) key, and then starting Firefox. https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode
A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?
This could be a problem with the mouse (there are mouse wheel actions with holding Shift or Ctrl or Alt).
- Try to press the mouse wheel a few times when this happens.
- Try to press all the status keys (Shift, Ctrl, Alt) a few times to see if that helps to recover from this.
Maybe try another mouse in case closing and restarting Firefox or rebooting the computer doesn't have affect.
