Hi Barney Anne,
I suspect if it is happening all over, your browser settings may be messed up. You can delete your browser’s cache (In the browser’s Settings) and see if that fixes it up.
Like Walt said, perhaps you’d like to try a new browser.
Here’s more info about browsers if you decide to try a new one.

Hope this helps,
