Solution 1): Downgrade to Firefox 52 ESR. (Recommended until Mozilla gets their head out from their behind and stops ruining all privacy addons by design), and don't use Windows 10.
Solution 2): From your current installation, type in the address bar: about:config, say ok to the prompt, then type "general.useragent.override", and set this variable to blank.
Solution 1 is a complete non-starter. Solution 2 leads to a browser not supported error in Facebook, although other sites work. Any other ideas?
addons.mozilla.com doesn't recognise it as Firefox either.
So: I have managed to get back to stability by copying settings from my laptop, so it now thinks I am running Safari on Linux.
The relevant keys appear to be: general.appname.override general.appversion.override general.platform.override general.useragent.override general.useragent.vendor
Can anyone suggest settings for them that don't break Firefox?
I had to refresh Firefox. You lose your extensions but it works and changing your extensions is broken otherwise anyway.
In fact, the solution is blindingly obvious. reset all five keys to their default values and the problem goes away.
Thus, my browser (Firefox, Windows 10) is stuck with the wrong headers (Chrome, OS X). I have tried restarting Firefox and Windows, but to no avail. This means I cannot download Firefox extensions. How do I set it back to the correct profile?
