I don't think thank browsers really affect ones search results. It may be a result of your search history and cookies.
i m not getting any kind of difference... It might be possible u got different result coz of data-center...
browser do not effect on your keyword position so both are trsted and while you checking keywrd do not login in gmail account otherwise you will get wrong result
There is a possibility that Google provides a "slight" difference on search engine results based on browser type. Remember that Firefox's default search engine is Google.
Google doesn't differ due to what browser you use, however there are many variables in play - many of which have been already listed.
I think it caused your default google geographic, maybe your IE and your firefox is have different country google setting....
i think you are right for my keyword "desi masala" both internet explorer and firefox give differnt results
