Since Microsoft does not support the use of IE6 in conjunction with SharePoint 2010, users still using this browser will have problems accessing the site. Google Chrome seems to generally be able to render SharePoint 2010 just fine and Google offers a plug-in for Internet Explorer which allows sites to be rendered in a Google Chrome Frame within Internet Explorer.
A new version of the plug-in is available, which no longer requires admin privileges in order for it to be installed. The plug-in can be found here.
In order for this to work, the following modifications have to be made to the master page of the site:
Add a tag to the <head> element
<meta http-equiv="X-UA-Compatible" content="chrome=1">
Disable unsupported browser warning (optional)
Locate the following tag:
<SharePoint:WarnOnUnsupportedBrowsers runat="server" />
Change it this code:
<SharePoint:WarnOnUnsupportedBrowsers runat="server" Visible="false"/>
When Internet Explorer users open the site, the Chrome Frame plug-in will load and render the page instead.
Now, your mileage may vary of course for being able to use this, but for when you’re in an organization that is still using Internet Explorer 6 and is either in the process of upgrading or doesn’t have any plans yet, this could be a simple alternative for the transition period instead of having to resort to thin-clients or MED-V.
