addons.mozilla.org sees wrong Firefox version, won't let me install add-ons

I am running Firefox Quantum version 57.0 64bit. When I go to addons.mozilla.org I often get the message "This add-on requires a newer version of Firefox (at least version 55.0). You are using Firefox 52.0.". I am NOT using Firefox 52.0, I am using Firefox 57.

This is particularly annoying because I specifically waited before upgrading until my add-ons would work with Firefox 57, and now I can't even install them!

Hi

Please can you:

  1. Type about:support into the address bar
  2. Copy text next to User Agent and paste it into a reply to this thread

This will help us to get to the bottom of what is happening.

Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:52.0) Gecko/20100101 Firefox/52.0

Okay, that seems to be why this is happening...

This is the data just above:

Version 57.0 Build ID 20171112125346

How can I correct the user agent?
