I’m also running Mojave, and am still getting Firefox updates. Not sure why you aren’t, and I think their stated support back to 10.12 is still accurate.

Thanks for your reply. I feel a bit silly now. I just learned that I have Firefox ESR, which is different from Firefox:

I just assumed I downloaded the regular Firefox release, but evidently not.
