There are still two bugs open related to big-endian in Bugzilla: https://bugzilla.mozilla.org/show_bug.cgi?id=1244398 https://bugzilla.mozilla.org/show_bug.cgi?id=1718880 Plus, I'd be looking into the patches that Oracle is maintaining for Firefox on Solaris for SPARC which does actually carry fixes related to big-endian systems if I remember correctly: https://github.com/oracle/solaris-userland/tree/master/components/desktop/firefox/patches There is a very high possibility that there is a proper fix among these patches.
