[Closed] Clicking on URLs in Thunderbird causes problems with Firefox as default browser
Although this problem has come about with Firefox 14.0, I'm reporting it as a TB bug for reasons that will become clear as you read on. I've also reported it as a bug to Mozilla.
I have two machines which both run Firefox (non-portable version) as default browser. Up to and including Firefox 13, if I clicked on a URL in an email in Thunderbird (portable) with Firefox already running on the machine, a new tab would open showing that URL, as expected.
