I get this error on a Mac running OSX 10.10 ("Yosemite"):
Firefox: CGBitmapContextCreateImage: invalid context 0x0. This is a serious error. This application, or a library it uses, is using an invalid context and is thereby contributing to an overall degradation of system stability and reliability. This notice is a courtesy: please fix this problem. It will become a fatal error in an upcoming update
Tor browser "latest Tor version". Is there anyway to remove this error? Is this a normal error? Does any body know what code might be the reason for the error?
