Changing default browser in KDE

[Richard S. Crawford]

I've given up on getting Evolution to sync with my Clie, but I've found that 
KPilot syncs with it just dandy.  So I'm now using KMail for my e-mail.

I would like to use Firefox as my default web browser.  I've changed the file 
associations in KControl so that html files bring up Firefox instead of 
Konqueror, but this seems to be a problem for php files.  When I click a 
link, it looks like KDE downloads the file and tries to open it locally 
instead of sending Firefox straight to the site.  I tried adding *.php to the 
list of file extensions associated with Firefox, but that didn't do the 
trick.

Any thoughts?
