I have a problem, firefox is causing my screen to flicker and mess up the interface on my computer. I have no addons installed. I am always surfing incognito. In many cases the screen flickers a few times, and if I am fast enough to close Firefox the problem goes away. This problems does not happen with any other software that utilize on my computer. This occurs for the most part when I am on social media sites like FB, Linkedin or IMDb. Sometimes one can see that some square grafics as an error with in the browser window. And then after a minute or so the flickering starts. These grafic errors never occur outside the browser window and when they appear. But when the screen starts to flicker, the grafic errors occur all over the screen to the point when I close Firefox. It goes back to normal. If I am not fast enough, os stalls and I have to perform a hard reboot, with powerbutton.
