I already have Firefox version 102.7esr (whatever that means), but one of my online accounts required an upgrade in order to access it. So I installed version 109 last night. It was working fine, I thought, but it won't open this morning. My version 102 is working. Wouldn't 109 automatically replace the older version? Are they competing? How do I get 109 to work again and replace 102?
