Login through parameters

[bilbo2]

Hi,

I'm having my Webmail as a button in Firefox. Is it possible to login automatic using a URL, like let's says:

Code Select Expand

http://webmail.domain.com/?_action=login&_username=xxxx&_pass=xxx
This fails for me, how is the correct typo for this. This could save me a lot of time, instead of always enter username and password, since
I use my Webmail as primary mail client.

Thanks in advance.
