Browsers add-ons and plug-ins are nice features that can sometimes become annoying. Flash Player, for instance, is nice but extensively used in boring commercial ads.
Fortunately you can either disable the annoying add-on or allow it to run only on specific sites.
To do this in Internet Explorer:
- First click Internet options / Programs / Manage add-ons.
- Select the add-on and click More Information.
- By default, the add-on is allowed to run on all sites. This is displayed as * (asterisk). Click Remove all sites.
- Click OK to confirm your choice and close the Internet options dialog. You are done.
- Now, the add-on will no more be executed on any web site.
- In fact, each time a web site needs to run the add-on, IE will ask you if you want to allow it to run on this specific site.
- The list of allowed web sites is then maintained by Internet explorer.
After some weeks / months / years… this list may become quite long.
Now, what to do to remove just ONE site or TWO of this allowed list?
Internet Explorer allows you to REMOVE ALL SITES… There is no button to remove just ONE site!
So, you remove all sites and start a new history again… More annoying than letting the add-on run on all sites… isn't it?
WHERE does IE keep this list? Mystery!
After a lot of search, I didn't find any information. Until….
Yes… it is in the registry (Please be extremely cautious when modifying this vital thing: The registry)
HKey_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Ext\Stats\[add-on class ID]\iexplore\AllowedDomains
Example for Flash Player add-on:
When all sites are allowed:
When only some are:
Now, if we want to delete just ONE web site, simply delete its key.
