I am working on a Chrome extension that needs to inject scripts into data:-URI pages.
When trying to execute the javascript I get an exception:
Error during tabs.executeScript: Cannot access contents of url "data:text/html;charset=utf-8, … ". Extension manifest must request permission to access this host.
But which permission would work for me? I tried data:*, <all_urls>, *://*/* - none of these worked. Also the activeTab permission did not do the trick. Any ideas?
