I cannot click on any email links on any pages. It causes Firefox to open many, many multiple tabs, which I cannot close. My only recourse is to quit Firefox and relaunch. It happens most of the time, so that in order to click an email link I must open another browser altogether.

However did that happen to get set like that? Whatever happened, that was the problem. Thanks so much.

Same problem here, but my mail application is set to "always ask", not to Firefox.

For the record, I have Windows 7.

Thoughts? Solutions?

You can 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.
You can open about: pages via the location bar like you open a website.


Did you try to delete the file mimeTypes.rdf in the Firefox Profile Folder?
