I was checking around to see if they would fix this, and, as Marius Gedminas points out, they see this as a feature (and I started to support that after reading arguments). Upstream won't fix this. I doubt Ubuntu will fix it as well...
It seems this is when they changed the behavior: https://bugzilla.mozilla.org/show_bug.cgi?id=325541 (and GOD they have sooo many bugs on this). I'll try to find the upstream bug report that wants this to go away (which probably be marked as "wontfix")... ** Bug watch added: Mozilla Bugzilla #351218 https://bugzilla.mozilla.org/show_bug.cgi?id=351218 ** Also affects: firefox (upstream) via https://bugzilla.mozilla.org/show_bug.cgi?id=351218 Importance: Unknown Status: Unknown -- The backspace key pages up instead of going back in history https://launchpad.net/bugs/60995 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
