Problem with the TB/Firefox linkage

[rhomp2002]

When I click on a URL in TB it should show up on FF.  It used to but all of a sudden it stopped working.  Now I have to left-click on the URL, tell it to copy the URL, open a new tab on FF, paste the URL in FF and hit enter to get the links to work.  PITA.  I think there has to be something in the configuration in TB that will make this work again.  Just not sure what it is.

What does TB stand for?

URL is Uniform Resource Locator?
FF is Firefox?

open menu: Edit / Prefences, go to Advanced tab than General tab and open Config Editor [click: I promise I'll be careful :p ].

 find key

Code:

network.protocol-handler.app.http

doubleclick and enter: /usr/bin/firefox

see in your terminal what the command which firefox returns. that's your http protocol handler application.
