Having upgraded to FF4 I then tried to set gmail as the default mailto. It didn't work so I checked in tools/options/applications and mailto isn't there. I've tried making changes to the network protocol settings in about:config and no joy. Anyone know anything about this?

Delete mimeTypes.rdf in the Profile Folder


You can also look at the network.protocol-handler.external.mailto prefs on the about:config page.

If network.protocol-handler.external.mailto prefs are user set (bold) then right-click and Reset them to the default value.

To open the about:config page, type about:config in the location (address) bar and press the "Enter" key, just like you type the url of a website to open a website.
If you see a warning then you can confirm that you want to access that page.
