Using LXLE (Lubuntu) 12.04 32-bit. Using Thunderbird and Firefox for main Web apps.
Whenever I click on a web link within a message in Thunderbird, it opens a new tab in Firefox, but always opens the page at this URL: "http://www.lxle.net/index.php?x=about".
This behavior doesn't change when running Firefox in Safe Mode. Firefox is not configured by me in any way to redirect to that LXLE main page, so it must be originating from within the distro OS.
Changing settings for the default web browser hasn't changed this behavior, either from the GUI "Preferred Applications" app, or from the command "sudo update-alternatives --config x-www-browser".
How to get the email-based links to open properly in Firefox?
