Hi, I am making the SEO reports for a travel agency  and I have the following problem. SEOmoz shows me the website is on page 1, for a keyword. Yesterday, a google search with firefox showed me the same position, while, searching from a different computer on google using firefox gave me another position. The URL shown was also different. I asked some friends to do the search - the results were the same - first page. Today, firefox shows me the second URL on the 4'th page, and the result from the first page of google does not appear, while Chrome still shows me the first URL on the first page. I have no idea why the URL that was ranking well does not appear on the first page with Firefox, and why it appears on the first page with Chrome, or why the URL that was ranking bad -meaning page 4, appears on Firefox but does not appear on Chrome. Can someone give me some advice?
