What version of Windows do you have?

''<p>dshort13 [[#question-1480063|said]]</p>'' <blockquote>I have 64 bit windows pro but when I try to update I get error message saying I need to have windows 10 or newer </blockquote> Is this on the same system you are using to post this question? as it appears to be Firefox 133.0 on Windows 10/11 There has been some threads like this in last while that were due to people running the Firefox version they had in Windows Compatibility mode to run like you were using it on a older version of Windows which also changes the Firefox UserAgent to show as if you are running it on say Windows 7 or 8 for example. Firefox since 116.0 and later requires Windows 10, 11 to run.
