Map tel: links to get request in Firefox

Question

We have a PBX system in our office that can be triggered to originate a call to a given number on your extension whilst you are logged into the User Control Panel (so you get the right cookies) by visiting http://pbx.host/some/path?number=0123456789.

Is there an extension or any guides on writing an extension for Firefox to pass tel: links to a given url.

Answer 1

This might help :

• Open regedit
• Navigate to HKEY_CLASSES_ROOT\tel\shell\open\command
• Double-click on (Default)
• Copy and save the current value as a backup
• Replace it by :
  "C:\Program Files\Mozilla Firefox\firefox.exe" "http://pbx.host/some/path?number="%l""

I haven't tested it so errors are possible, but let me know how it works.
