This suddenly started yesterday. I reversed the buttons, thinking something was wrong with the mouse, but it still does it. Especially annoying when I’m reading email. I click delete on one I finished reading and several emails after it suddenly disappear (they open long enough sometimes I can make out the title then they are gone)
Also, Firefox retrograded itself about a week ago and I can’t seem to get a newer version to open (I’m a newbie to Linux still) Any help appreciated!
