Apparently the latest 2.53.22 version of #SeaMonkey no longer has binaries for 32-bit x86. I suppose it makes sense since they removed #NPAPI support (which I think is still a mistake, and ironically NPAPI could've helped them with the increasing amount of websites being designed only with Chrome in mind with an add-on like #SubWebView: https://github.com/teknixstuff/subwebview) so might as well make release engineering a bit easier.
