Yes... I know... but my Firefox on High Sierra was offering me ESR 115.1 so as to extend security for about a year. I was away for a few days and thought I'd do the update to that when I got home. Now unfortunately it isn't offering it anymore and says my Firefox is up to date at 115.0.2 so where can one find ESR 115.1 or whatever version is correct now?
So... I HAVE found ESR 115.0.3.
It doesn't specify if that would the correct one... it was just this last weekend that Firefox was asking to "update to ESR 115.1" the normal way but that's not there anymore after just a few days so???
