[QUOTE=devaldivia] no worries :)
It happens both when I navigate to my LAN preview address or to my localhost address. I just upgraded to the Personal edition today and I noticed I didn't like the CSS so I wanted to look at it in Firebug.
From within C2, if I change my Preview Browser to FF, FF also crashes immediately when I click the Run Layout button in the top menu.
In fact, I wanted to make sure it had nothing to do with my project so I just tried it with both a completely empty .capx and with a .capx that only had 1 button and it crashed in FF all cases.[/QUOTE]
Ohh, remember if its a new install of firefox, then install flash & java (with plugins) for the browser
