Thank you for the great news, Julien!
I haven't actually tried this out on release Fenix, but I believe it should
be possible to set the pref there too using the Multiprocess Toolbox in
about:debugging and executing
`Services.prefs.setCharPref("logging.config.modules", ...)`
Though if I understand correctly, logging is currently disabled on late
beta and release? https://bugzilla.mozilla.org/show_bug.cgi?id=1841818
