Hmm, that's odd. Normally if you use privacy.resistFingerprinting, Firefox disguises your version as the most recent ESR (Extended Support Release), which was 68 or 78. But yours identified as Firefox 80. ???

Just after posting this I found the answer at https://support.mozilla.org/en-US/questions/1288587. That resolved the problem after I cleared the cache.

The reason for that must be that I had set privacy.resistFingerprinting to false having read somewhere else (just where I cannot remember) that that might fix the problem, but I didn't then for some reason think either to force a refresh or to clear the cache. Then I made the initial post. And then I saw the article referenced above and I thought to clear the cache. I hope that it is no longer odd. Sorry!
