I use firefox on Centos 6.10 ... I have tried several times. I get an email. I change my password. I get successful password change message. login fails. Show password to check. It is correct. Try again .. it fails. I have to use a different email account just to post this problem. The original problem was different. I could not even post the original problem due to the fact that I could not login to my mozilla account with id shinobi59@gmail.com Original problem: Upgraded to Firefox Quantum. My video no longer works. It worked fine just before I updated to FireFox Quantum version 60.1esr (from Centos Repository) ... I know you are going to blame them and not help but I thought I would ask. Also if I try to upload or download a file ... firefox crashes and burns. You should add a feature to roll back to the previous version so that I can go backwards when things break so that I can at least function ... I depend on my browser ... I am taking all kinds of professional education courses and now I am stuck. Why are you guys breaking firefox??
