I'm on a Mac and been using Thunderbird as my email client and Firefox as my browser for a couple of years and I really like both of them. But I'm having a problem with mailto links on both and though I've searched all kinds of message boards and listservs, I can't seem to find the answer to it. Here's the thing: In Thunderbird, if I click on a mailto link in a forwarded message, I get a box which says "mailto is not a registered protocol" In Firefox (3.0.1.0), when I click on a mailto link, I get a Thunderbird window to come up, but the email address doesn't show up in the "to" line. So I have to copy it from the website and then go back to Thunderbird and paste it. I know this probably has something to do with statements/strings in the about:config. But after lots of attempts at trying to fix the problem, I still haven't been able to get mailto links to work in either Thunderbird or Firefox. Has anyone out there had the same problems and fixed them??? Thanks, Lynn -- Lynn A.
