I went to a foreign country last week and used their wireless connection. Now every time I put my cursor/mouse over an object on the page a white box appears. Typically when I used to do this, for example over a Google home page special occasion art, a box would appear under my mouse saying what that object was, but now I just get a vertical rectangle shaped white box. I uploaded the latest version of Firefox when I got back to the US, but it's still doing it. I don't have this problem with internet explorer or other browsers - it's just happening with Firefox. Please help! Thanks
