hi, thanks for following up with your crash ids. these crashes look like an issue caused by hardware acceleration - please try [[Upgrade your graphics drivers to use hardware acceleration and WebGL|updating your graphics driver]] - this should be the right link for your configuration: http://support.amd.com/en-us/download/desktop/legacy?product=legacy2&os=Windows%207%20-%2064 in case this doesn't solve the issue, please disable hardware acceleration in the firefox ''menu ≡ > options > advanced > general'' (that setting will take a restart of the browser to take effect).
