Thunderbird drops to address when linking from mailto links

I am using Thunderbird 60.6.1 and Firefox 66.0.5 winth Windows 10

I find that when I click on a link in Firefox to a mailto link that Thunderbird opens the compose window but there is no Email address in the to line.

If the mailto link includes a subject then that is carried into the compose window but the Email address remains missing.

I have gone through the process of resetting the mailto defaults in the Windows 10 settings to no effect. I have checked the Windows registry and there is a key which reads:

HKEY_CLASSES_ROOT\mailto\shell\open\command

With the value: "C:\Program Files (x86)\Mozilla Thunderbird\thunderbird.exe" -osint -compose "%1"

I have tried removing the osint switch but that makes no difference.

I'm stuck trying to work out what to do.

Does anyone have an idea...?

try disabling all your add-ons after you restart from the help menu and see if you still have a problem. I have not seen any other reports, I am not seeing this on Windows 10.

Thanks Matt... As soon as you said to disable add-ons I nearly swore. Of course that is the first thing to try when diagnosing a problem.

It was, indeed, an add-on causing the problem. Sadly, it is an add-on I use very frequently but at least I know where to go from here. Many thanks.

What add-on? always good to know which are having issues. Also helps those that google the same thing.

The errant add-on was Signature Switch from http://mozext.achimonline.de/

There is a new version in beta for beta versions of Thunderbird.

Rather than wait for this I've taken a different approach to switching signatures using identities.
