Bug tracker blocked

Hi all, I would like to try and contribute but ... The site http://bugs.netsurf-browser.org/mantis/ is blocked at my workplace by Websense as being in a Static category: Proxy Avoidance. Is there anything that can be done to alleviate this please ? I do believe that Websense is a third-party product which does regular updates. TIA -- Regards from Dave Lawton HTML emails are just a security risk, and nobody needs that.
