Hi all, I'd like to return to using Firefox, but I need Google Sheets for my work, and this bug makes it unusable. Basically, here's what happens: I click on an empty cell, press "=", and then click on another cell (e.g., "=A1"). After pressing + or *, the text cursor jumps back between the selected cell and the + or *. This bug only occurs in the Firefox browser; all other browsers work fine. I don't have any extensions installed. I haven't used Firefox for about 2 or 3 years, but I thought I'd give it another try, and the bug still persists. I cannot explain it because it's even happening on a new PC with a new Google account. I tried the same on my girlfriend's PC, and the bug also appeared. I have already checked the shortcuts for Firefox and Sheets, but there is nothing suspicious there. I also considered the keyboard layout. I live in Germany, so I have a German layout, where the + is located to the left of the Enter button, and * is created with Shift +. However, this conclusion doesn't seem to help with finding a fix, lol. (By the way, the * on the numpad works fine.) Any ideas on what could be causing this problem?
