How to get latest version of Activity fedd solution for On premise OR IFD

Activity feeds are giving error in Firefox "While your organization is being updated, you can only view Activity Feeds in Internet Explorer. After the latest Activity Feeds solution is installed, it will work in all supported browsers."



Solution  for on premise or IFD:
1.check the version of installed Activity feed
2.if it is 1.0.1.20302( available solution in MS Site) then  update to latest version "ActivityFeeds.cab
1.0.3.21214"
3. To get the latest version for on premise or IFD by following the below steps.

•   Download and run the UR12 Server update from the Microsoft download site on the CRM server, you only need to get as far as the extraction complete / welcome screen not all the way through.
•   Use windows explorer to look through your hidden temp files for *activityfeed* and it will come up with a couple of CAB files ('ActivityFeeds_1.0.1.CAB' and 'ActivityFeeds.CAB')
•   Import the 'ActivityFeeds.cab' as a solution and it should tell you that this will update the one that is already there. The version number of this new one should be indicated as 1.0.3.21214
•   Make sure that you overwrite existing customisations (best to test this in a dev environment before doing this on any form of live solution as you can overwrite changes you have made elsewhere with this!)

just run the downloaded UR packache with /extract:<path>, for example I created C:\Temp\CRM and called the package like this:

CRM2011-Server-KB2791312-ENU-amd64.exe /extract:C:\temp\crm
then I found the file needed in as c:\Temp\CRM\Actions_Org\Install\Solutions\ActivityFeeds.cab
