Certificates not working on OS2008 mozilla browser
 

I am using the default browser and would like to access my companie's OWA. To do that, I installed a certificate that works on Google Chrome, IE and Firefox on my home desktop. It installed fine on the N810 but when I open the OWA site, I get a 'server error' - the URL is definitly correct.

So - my question is, does the default browser support certificates and if so, how do I install it into the browser as there seems to be no way of doing that I have found. On my desktop mozilla browser I had to install the certificate but can't find a similar function on the N810 browser.....really frustrated so any help much appreciated.:(
