python: Unmet dependencies for Firefox

[pmenzel]

Firefox 98.0 aborts with the messages below:

Work around is to not use the system Python installation.

Well, IMHO what you deem to be a 'work around' is actually the correct way to do it, since there is no way for an installed firefox to adopt to an updated python.
