ESR means "Extended Support Release" I know that, and the purpose of this particular release is to offer enterprises enough time to make regression and compatibility testing.

Do your computer still running in Windows XP?

As said by SlyCooperFan1, Firefox 45 ESR is really outdated, the most recent release is Firefox 68 ESR. I'm sorry for you but, the more time goes and the less compatible your browser will be. :-/
