I have had Firefox on my Vista OS desktop for some time. When I start Firefox it opens Google as my home page. However, today I was not able to have anything open when typed into the Google search bar. Thinking it might be a Google problem I opened up Internet Explorer and accessed Google and brought up the main search screen. I typed something into the search bar and Google responded as expected. So the problem is not Google's but mine! What have I done? I do not believe I have changed my settings but others have had access to this computer so I can't say for sure if something has been changed or not. I do not want to un-install/re-install Firefox for fear of losing my bookmarks and pre-set tabs. Please advise! Bob
