I am using the the native web-development tool from Firefox to edit and change some of the HTML/CSS code. I am sending you a photo of my screen when it freeze my Macbook Pro. Actual results: The entire mac book screen froze, my Macbook became unresponsive and restart. Looking into the Mac os x Consolte I get a lot of same angry message before the automatic reboot of my Mac. The error log is following: 2014-11-07 10:16:59.317 AM firefox: CGContextSetInterpolationQuality: 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.
