SharePoint Needs optimal browser for best performance and you would need to know the supported browsers before you plan to use it for your company, no points for guessing that Microsoft would support their own Browser much more than the other popular ones available in the market.
- IE6 is not supported by Microsoft as it’s an outdated version
- IE 7 to 11 are supported in both 32 and 64 bit flavors.
Some functionality in SharePoint Foundation 2010 requires the use of ActiveX controls. This produces limitations on browsers which do not support ActiveX. Currently only 32-bit versions of Internet Explorer support this functionality. All other browsers have the limitations.
