Alright, so this "works for me" [tm] to fix this problem: Open firefox and enter "about:config" into the location bar. Set the filter to "mailto". Locate the "network.protocol-handler.app.mailto" line, right-click and select "reset". Close firefox. Open nautilus/thunar/whatever and go to your firefox profile directory (/home/<user>/.mozilla/firefox/<some weird string>/) There's a file called "mimeTypes.rdf". Remove it (or rename it, if you're the cautious type). Start firefox again. Right-click anywhere and select "Send Link...". A window should pop up that prompts you to choose your mailer application. Locate /usr/bin/thunderbird (or whatever is your preferred app). Click ok and the compose window should show up.
For the curious: If you now take a look at the about:config page, you won't find the network.protocol-handler.app.mailto property anymore. It seems it is not used anymore in firefox 3, however having it still set after upgrading seems to seriously confuse firefox 3. -- mailto links in Firefox 3.0b5 do not open up Thunderbird compose windows https://bugs.launchpad.net/bugs/222944 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
