Thunderbird Opening Links

[R. G. Newbury]

In a moment of insanity, I installed google-chrome on fedora21. The 
Chrome installation made chrome the default and changed the 
network-protocol handlers in Thunderbird to 'chrome'. I have since 
removed google-chrome and manually edited the entries in TB back to 
firefox. I think I have properly set firefox as the default browser.

BUT, when I click on a link in an email in tbird, Nothing happens (even 
if firefox is open).

Getting tired of copying link location, and pasting into the address bar.

Can anyone assist? My google-fu produces nothing.
