As I said in https://bugzilla.mozilla.org/show_bug.cgi?id=135884#c64, this bug is known for a long time now.
People who are annoyed can disable this behavior via middlemouse.contentLoadURL but disabling it by default is the way to go. As Ben Bucksch said in https://bugzilla.mozilla.org/show_bug.cgi?id=135884#c62, the minority who prefers the current behavior could simply enable it. For the others (the majority), the current behavior is surprising, confusing, not handy and is even security relevant (noticed by Ben Bucksch) when a user is pasting a password in a field but misses it by a pixel, sending the password through the network. He wrote a patch but has never been commited. Can someone review his patch ? (and possibly commit it ?) >> https://bugzilla.mozilla.org/attachment.cgi?id=504212 Having this long standing bug fixed in Fx4 would be really, really great. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/353318 Title: Middle mouse button invokes 'invalid URL' -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
