iMac blue progress bar keeps running...

Have an iMac, on certain web pages, the blue progress bar continues to run/refresh. I have tried restarting the computer several times. Any idea how to fix this?

You must be more specific, if it’s only certain web pages then post a sample so we can test it.

For instance, if I go to youtube, the blue progress bar just keeps "running", on other web pages, it doesn't do it at all.
