[gentoo-user] etiquette for stabilization request

I am running firefox-24.8.0, which is highest stable (highest testing is
33.0).

Several sites, in particular mail.google.com, report that "This version
of Firefox is no longer supported. Please upgrade to a supported
browser".

Does that warrant a stabilization request.  I have never filed one
before and do not have a feeling of what is considered justification.  I
should add that other than generating the above complaints, firefox is
working fine (including with mail.google.com).

thanks,
allan
