OK, not really, but Firefox can be configured to block certain domains from displaying Flash content.
In addition to these tests, there are tests of subdocument Flash blocking here.
Since the results of these tests are dependent on the setting you have picked for Flash (in the Plugins tab of about:addons), there is an Expected column below for each setting.
