I was trying to fix a problem with eBay where I was unable to send a message to a seller. (A problem I have since discovered had nothing to do with Firefox it has to do with eBay). I had asked GPTchat for suggestions and it had me open a terminal and run some commands (don't remember what it was). while running this command we lost power and since then I cannot resize a Firefox window. However other windows like Dolphin or LibreOffice are unaffected. All else appears to run fine
