How do I get AOL Webmail working for default mailto again? I used to have the AOL mail site as Firefox's default mail. Somehow when I opened up Thunderbird recently for something, it up and decided that it had to be my default for mail links in Firefox, too, I guess? Maybe something changed with a system update a while back, I'm not sure. In case Thunderbird really did decide to take over, and will do it again next time I open it, what's the setting in that to get it to stop doing that? What did I put wrong in there? At any rate, I haven't liked the change. I don't seem to be able to pick AOL from the Applications options in Firefox's settings, and when I pick to "use other", I get a dialog that'll only allow me to pick an application file, and won't allow putting in the URL for AOL Mail. I did not use a helper app before, and the extension I tried from the Firefox Add-ons site doesn't work right. It opens the AOL page, but doesn't even open a new mail compose page, let alone fill the email address I clicked on as it ought to. I'm guessing this will take editing something in about:config, but I don't know what to put in there. What's the fix?
