Thunderbird 91.1.1 doesn't like Leafnode.

At least, that's what it looks like.

After I've sent this I will try and raise it with the Thunderbird mob, 
but I don't expect to get much traction there.  :-(

Windows 10, Pro, 64 bit.

Solaris 11.4, Leafnode-1.11.2, been stable for years.

Upgraded Thunderbird 78.14.0 to 91.1.1 (after saving my profile), 
everything looks okay.

Read a couple of newsfroups, no problem, click on another one, blam!

Thunderbird offers to report the failure, fails to do so!

Rinse, lather, repeat a couple of times, cannot find a pattern, there 
are 93 newsgroups in my news.rc file.

I'll activate debugging in Leafnode, and see if that shows me anything.
