Whenever I open Office (outlook.office.com) in Firefox, it doesn't work the same as when I open it in Chrome. I will be typing an email and suddenly the cursor stops typing words. I wait a minute to see if it will catch up and it doesn't, so I have to re-type. Half the time when I hit spacebar, the space doesn't appear, I have to hit it multiple times for it to work. At random times, I will be typing in a reply to an email and suddenly it pops up saying it is archiving a message, or it will pop up a new outgoing email window. I thought it was my keyboard, but realized it ONLY happens in Firefox when using Office.com. Any ideas on how to fix this? Thanks!
