Seo And Google

Google Seo SERPS question?
How is it that if I use two different browsers I can get a different number of search results? For example one term (three words) brings 231,000 through Google Chrome and Internet Explorer, but only 196,000 results using Firefox. Besides, Google Website shows that he has visited often in the top of the SERPs? I have a new website I've been working, often seen in chrome to check that shows well but now I find that the # 1 in Google Chrome for this term. That same site is located on page 4 in IE and Firefox. Thoughts?
Google has data centers around the world with more in some countries and may each have a different set of databases of results. Therefore, it could be the case your browser 're looking at different sets of results. With regard to visit frequently, used to be a suggestion that this was the case and if Google is registered to your account Google can "star" an outcome, but the vast majority of web pages are at the top of the results for reasons other than the fact that you visit them frequently.
