When we first moved Slackware to the Firefox ESR channel, the motivation
was to keep Firefox secure while delaying a requirement for Rust at build
time. Of course, eventually that ESR version reached EOL and we had to
introduce Rust into Slackware 14.2 in order to continue providing updates.
Eventually that also ran into roadblocks as Firefox required first newer
C/C++ compilers, and then finally a newer libstdc++. To continue, we'd
have had to bump GCC to a much newer version, making other maintenance
difficult or impossible. At this point, the latest Firefox has no additional
dependencies beyond those of the ESR version, and it's unlikely that it
will be any more difficult to keep it maintained. I think we all want the
Slackware 15.0 release to be as good as possible, and most users will be
better served if we resume following the latest desktop releases.
Thanks to LuckyCyborg who can always be counted on to give me a friendly
kick in the rear end. Thanks also to ponce for the updated gkrust patch.

Rebuilt with -proprietary-codecs and -webengine-proprietary-codecs. When
combined with -webengine-ffmpeg (use system ffmpeg), this doesn't actually
build any proprietary codecs, but allows them to be used if they happen to
be built into the system ffmpeg. Thanks to alienBOB.
