Mozilla study Microsoft, before official Firefox 4.0 release Firefox 4.0 RC version. Do you think that Mozilla Firefox has same way with Internet Explorer.
I think that Microsoft studies Firefox rather than the other way around (like how they "studied" the Google search results that was news a couple of weeks ago).
Exactly. IE9 is 2-3 years behind where Firefox is today and will be even further behind Mozilla, Chrome and Opera when it gets introduced later this year. Microsoft is the one doing the copying, not Mozilla.
