Using Firefox or Chrome... Is there a way to control which sites are allowed to run flash and disable it for all others?
The procedure for the current version of Chrome is detailed below.
- Open a tab with
chrome://flagsand verify the the following are set to Default : Prefer HTML over Flash and Run all Flash content when Flash setting is set to “allow”
- Open another tab with
chrome://componentsand under Adobe Flash Player, click Check for update and wait for it to finish
- Click on the Chrome menu button at the top-right and then on Settings
- Click on Show Advanced Settings
- Under Privacy click on Content Settings
- In the dialog, under Flash ensure that Ask first before allowing sites to run Flash (recommended) is selected (don't do Allow sites to run Flash)
- Now Flash is allowed and you need to enable it for your specific sites
- The hard way to specify an allowed site is under Content Settings – Flash to click on the Manage exceptions button and add each site's URL with Behavior set to Allow
- The easy way to allow a site is to go to it and then click on the little icon to the left of the URL in the address bar, and set Flash to Always allow on this site instead of the default which does not work in the latest version of Chrome.

For those using Opera who wish to do the same thing, you can shut off plug-ins (which includes Adobe Flash) for any web site by following these simple steps:
- Right-click on the web page
- Select "Edit Site Preferences..."
- Activate the "Content" tab
- Disable the "Enable plug-ins" checkbox
- Click the "OK" button
To enable again, repeat the above steps but read step 4 above as "Enable" instead of "Disable."
