Hi, try turning off hardware acceleration - Upgrade your graphics drivers to use hardware acceleration and WebGL

And disable hardware acceleration in Flash - Adobe Flash plugin has crashed - Prevent it from happening again

If your question is resolved by this or another answer, please take a minute to let us know. Thank you!

I tried disabling hardware acceleration, but no fix. It's very strange and the only reason it is happening when I click on a piece of text I get I blinking black and white text icon that you would see when you type into a search engine, but for some reason appears on the bottom left corner of videos and text that I click on. Any solutions, I would greatly appreciate it, cause it causes some of my add ons to not allow me to select certain boxes. I already tried refreshing Firefox disabling all add ons, but no fix. This started happening the as soon as it was installed.
