Just a follow-up from the original poster here.  Despite all the advice, 
this issue still isn't resolved. FireFox is set as default browser, but 
clicking on links in e-mail (Thunderbird) still connects to Chrome. 
(Thunderbird preferences explicitly set FireFox for HTML files.)

Any other ideas would be appreciated.  Thanks.
