This problem began a few days ago...otherwise Waterfox has been great. When I'm trying to use my printer and I click on the Print Properties button, this error appears: Function address 0x77b580a0 caused a protection fault (exception code 0xc000000) Some or all of the property pages may not be displayed. When I try to click on this error box to close it, Waterfox freezes. I deleted Waterfox and downloaded it again, but the Error is still there. Thanks!
