Over about the last week I have had three Windows updates. After the second of these updates I discovered that moving from one website to another or moving from one page on a website to another page would result in nothing more than a continuing horizontal moving blue ball going back and forth in the address area. After some testing this appears to continue without any further Firefox response or internet activity. After checking online there was a suggestion about clearing the cache so I tried that several time clearing everything in the Privacy area of TOOLS. This had zero effect, at least after the windows updates. (NOTE: The most recent third update did not clear the problem.)

I thought you might want to check this for yourselves.
