You can disable Adobe Flash animations in websites by disabling the Adobe Shockwave Flash Object using the Manage Add-ons dialog in Internet Explorer, or by setting a "kill-bit" in the registry. What if you want to enable Flash animations by default on a handful of sites (whitelist) but not on other sites? In Internet Explorer 7, only the developer of an ActiveX control could configure it as a per-site control, using the SiteLock ActiveX Control Template. In Internet Explorer 8, it’s possible for an end-user to enable ActiveX Controls on a per-site basis, via the Manage Add-ons dialog.

How to White-list Sites for Adobe Flash

1. Open Internet Explorer, click the Tools menu, and select Manage Add-ons

2. Select All add-ons from the dropdown box

3. Double-click the Shockwave Flash Object.

By default, Flash ActiveX control is set to run on all sites.

4. Click the Remove all sites button, and close the dialog. This prevents Flash ActiveX control from running, for all sites.

5. Close the Manage Add-ons dialog

6. Browse to a website (e.g. youtube.com) for which you want to enable Flash animations. You’ll see the yellow information bar requiring your permission to run the control.

8. Click the information bar and choose Run Add-on.

The animation runs, and the current website is added to the white-list automatically. This will be reflected in the Manage Add-ons dialog, as well.

Registry Settings

The white-list data is stored in the following registry location:

HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Ext \ Stats \ {D27CDB6E-AE6D-11CF-96B8-444553540000} \ iexplore \ AllowedDomains

Where {D27CDB6E-AE6D-11CF-96B8-444553540000} is the Class ID for Adobe Flash ActiveX Control. The Class ID varies for every ActiveX control.

The allowed sites are added as subkeys to the AllowedDomains key.

This key can be exported to a .REG file and deployed across other PCs using Group Policy.

    Very interesting, Ramesh, very interesting. If only there was a way to block certain sites and allow the rest…

    Of course, it is perhaps possible through adding blacklisted sites to Restricted Site Zone and then adjusting settings there properly.

    If only this was also possible for Javascript. But it’s not an addon so not possible I guess without an addon that disables it on blacklisted or whitelisted sites?
