cockpit-project: unable to login after Firefox update

[Bigbiz]

After a recent update of Firefox I can't log in in my server using Cockpit, it says:

This web browser is too old to run the Web Console (missing selector(:is():where()))

I'm using Ubuntu Server 22.04.01 and I installed Cockpit via Jammy-Backports but the version installed is 276.1

The problem is solved installing Cockpit version 277 but it's not in the Jammy's backport repository.

Here the link where is explained the problem and the solution:

Thanks in advance for the attention.

The official fix just landed in jammy-updates today, see the duplicate bug. If you use backports, tis is also fixed in 276.1-1~bpo22.04.1
