2D not starting in Firefox, Security warning in Internet explorer

 Tried to start 2D with firefox for my league race this morning and it didn't load up, just a blank screen.

When i logged into iGP from IE it gave this message: Internet Explorer blocked this website from displaying content with security certificate errors.
which i had to select "Show content" for 2D to load.

Don't know if this is a common issue or something on my side but i was only able to get it to work in IE.
Firefox wont load or give that error message so maybe an option in settings for firefox to ignore this certificate error.

It's not loading for me either. Not in Safari and not in Firefox. Can't load it in chrome since it doesn't support the latest java plugin.

Running Os X 10.8.1 and Java 7 update 7

Firefox 15.0.1 + Java 7 Update 7 works for me. (I'm on Windows XP.)

Did work for me til about lap 6, then it died. That's my season done, thanks a tonne.
