(Keywords: nightly-community)

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:94.0) Gecko/20100101 Firefox/94.0

Steps to reproduce:

I updated an existing Windows 10 installation to Windows 11. Firefox Nightly that was present before the update has been updated to a newer daily release (2021-10-05) since then.

Actual results:

os.version in about:telemetry still reports the OS version to be 10.0

Expected results:

os.version should change to 11.0 unless Microsoft decided that the OS should still self-identify as 10 to the external programs for some reason

os.version should change to 11.0 unless Microsoft decided that the OS should still self-identify as 10 to the external programs for some reason

Microsoft decided so for compatibility reasons. Moreover, we explicitly cap the Windows os version to 10, again for compatibility reasons (bug 1693295).

Oh, this is about about:telemetry content? Please ignore the latter part of the previous comment. But the former part is still correct. Check if os.windowsBuildNumber >= 21996 to identify Windows 11.
