There's actually multiple bugs here. The only Firefox bug is that you even get offered to open mms links in totem at all, because totem doesn't have x-scheme-handler/mms defined in its desktop file. Once bug 727372 is fixed, Firefox will (correctly) display an error message saying "Firefox doesn't know how to open this address, because the protocol (mms) isn't associated with any program."
If totem can handle mms links, it needs to declare this in its desktop file (which is a totem bug). Thunderbird only works because it is still using gnomevfs, which is deprecated anyway and will stop working in the future too (but we will have proper gio support then). ** Package changed: firefox (Ubuntu) => totem (Ubuntu) ** Changed in: totem (Ubuntu) Importance: Undecided => Low -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to totem in Ubuntu. https://bugs.launchpad.net/bugs/751101 Title: mms: links don't open in totem -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
