At Tor's Q&A page was an error with Firefox reported. It seems that there is no according report, so I copied it over:

A user runs the current version of Tor Browser Bundle (4.0.2 or higher) under Mac OS X 10.10 Yosemite and gets the following error message:

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

Is the browser in full screen mode? Here is a possibly relevant Mozilla bug:
(this has been fixed by Mozilla but not in the version of Firefox that Tor Browser is based on).
