Error on opening links in Firefox from email in Thunderbird

Using Windows 7 sp1, 32 bit. My default browser is set to Firefox, and all http or https links from any program are opened in Firefox. There is no problem doing this from any program except from Thunderbird.

It's fine if Firefox is not already open, but when Firefox is already open and I click on a hyperlink in an email from within Thunderbird I get the message:

"Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window."

I've seen some comments on this error message, but all of them see to relate to problems with Firefox. However, since all other programs are able to open hyperlinks in Firefox without any problem, it seems to me that the problem must be with Thunderbird and the way it interacts with Firefox.

Any help will be much appreciated. Thank you!

Thank you for your reply, Gnospen.

Unfortunately that link doesn't help. I can easily get rid of the error message by closing Firefox and restarting it, but the error message shouldn't come up at all! I would like to make adjustments to that this message doesn't come up at all.

It doesn't come up when I open links from other programs - only when I open links from Thunderbird does it come up, so the problem seems to be on the Thunderbird side, not on the Firefox side.

Locate and delete any references to HTM, HTML or Firefox.

Restart Thunderbird and see if that helps.
