mailto function does not work

Whenever I click on a mailto: link, either nothing happens or, in some instances, a new blank tab will appear. I have Outlook set as my email client, and the program is running. Other browsers, IE and Chrome, link out to Outlook just fine, only Firefox (3.6.11) has this problem.

Re: mailto function does not work

Outlook is already set up as my default program for e-mail, both for Firefox and my System. All other browsers can do the mailto link out trick with no problem. My recent update may be corrupted/damaged or some setting is wrong.

Re: mailto function does not work

Did you check the Mailto settings in Tools > Options > Applications ?


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.

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.

'This worked great! This issue was pissing me off, I was familiar with about:config page but this shit had me stumped! Thanks cor-el '

Re: mailto function does not work

Yes, I'm having this problem, too. But I'm on a Mac, running Lion and Firefox 11. My mailto client is set to Outlook (in Office 2011 for Mac) yet Firefox just opens a blank tab. In Firefox 10.x, it tried to open my gmail account. What's up - all my settings are correct, yet my mailto client is simply ignored: opening the blank tab.

You know, my problem is that the Mailto icon in Options>Applications is that funky unrecognized icon. it's not that it's not there, or that it's not set, it's totally unrecognized. A bunch of other applications are also unrecognized, like irc, ircs, magnet and webcal. Also, most of the files in my profile folder are unrecognizable too. What's the story? What I gotta do?

network.protocol-handler.external.mailto

Hey - that worked! I've been asking this question for months and now finally found an answer. Thanks so very much! It works on a Mac running Lion, Firefox 11, and Outlook, at least. No more trying to load GMAIL or opening blank tabs. I owe you a latte, my friend.

Re: mailto function does not work

I've tried everything - fixed the 'network.protocol-handler.external.mailto' thingie and still didn't work. BTW, in my 'Tools > Options > Applications' I don't have Gmail - just Googlemail - I suppose it's the same thing? Anyway Googlemail doesn't work. Tried 'Use handlemailto' which uses "GmailDefaultMaker.exe" and it worked!!

Re: mailto function does not work

What OS are you running? Are you running Firefox 12? The "about:config" - "network.protocol-handler.external.mailto" was set to bold (false) and I just double-clicked it, setting it to "true" and my mailto opens Outlook all the time now.
