Why does Firefox think my machine is running Windows XP or Vista when it is running Windows 10?

Firefox keeps sending me warning messages about updates that have links to the article that explains why support for XP and Vista is being ended. When I go to the "About Mozilla Firefox" page it tells me that "You can not perform further updates on this system" rather than telling me that I have the latest version. Its as though Firefox thinks that I am running XP or Vista when I am running Windows 10. Can you tell me if this is the case and if so, what can be done about it? Thanx.

hi K-Bourg, please check that you haven't set firefox to run in windows xp compatibility mode - more details in: https://support.mozilla.org/en-US/questions/1232291

afterwards you could also download a fresh version of firefox from https://www.mozilla.org/firefox/all/ in order to switch from the esr update channel to regular release builds.

HI philipp

Thanks for your prompt reply. You were bang-on about the compatability - it was set to XP. Dunno why; my machine has never run anything earlier than Windows 7. Once I changed that setting and restarted Firefox it downloaded a brand spanking new version. Thank you very much for your help

If you did Firefox updates you likely have Firefox 60.2.0 ESR and not the 62.0 Release
