SharePoint 2010 - Browser Compatability

Hi All,
                Our company is in the process of creating multiple websites for the internet on SharePoint.  Although we are still in the early stages, I thought you may be interested in this breakdown of Browser Compatibility for SharePoint.  This is just a basic quick-test, on our company Intranet, but once we delve further into the project I will give updates via this blog:

Basically, all 32-bit versions of browsers are supported (meaning they will help you if you're having issues,) by Microsoft except Safari, and the 64-bit version of Safari is supported with ‘limitations’.  See the info and Matrix here: (

The issue is when ActiveX or Silverlight comes into play, where some browsers either do not use ActiveX/Silverlight or render it differently, or do not render it at all.

So, best way to see how they work is to test, so here’s some initial results from my testing:

Firefox – Works fine with Silverlight, menus, webparts.  Slightly slower to load the Ribbon

Chrome –Supports some ribbon functionality, but not all.  Silverlight does not work without the user manually installing a Silverlight plugin.  Certain Webparts do not show up at all when the page is fully loaded.

Safari -  Certain Webparts do not show up at all when the page is fully loaded.  Crashes occasionally when clicking through menus (although this may be the way our intranet is coded, as I am unable to find others with the same issue).  Silverlight works.  Crashed trying to access MySite.  Crashed trying to access Document Library on CONNECT.  (These crashes may also be due to our intranet design)

Conclusion:  Although issues like the Safari crashes are worrying, I can’t find any people online having the same short of issues.  This may mean that it has to do with certain customisations, but even so, it would mean that every time we make a change, we will have to have a set list of tests to run on every browser to ensure their functionality is not affected.  Some would say these tests are expected with any website design/changes, but I am looking more at the OOTB functionality that comes with SharePoint, rather than look & feel changes.


Version of browsers used:
chrome: 18.0.1025.162 m
safari: 5.1.5
Firefox: 11.0
