I've also run into this bug -- to get firefox to change the helper application, I had to edit the mimeTypes.rdf file by hand.
(The mimeTypes.rdf file is in your firefox profile folder, e.g. "~/.mozilla/firefox/9vwgqf0x.default/mimeTypes.rdf". If you know the path or name of the old helper, you can just search for it; e.g. I searched for 'helix-player' (which is no longer on my system), and changed NC:path="/usr/bin/helix-player" to NC:path="/usr/bin/realplay") -- Helper applications cannot be changed, even when asked to do so by Firefox. https://launchpad.net/bugs/55428 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
