When trying to figure out which one of the many links on a particular page is causing something to be broken, it would be really usefull to be able to whitelist / blacklist for a set period of time.
Just like the disable, 10s, 30s, 5 minutes, custom time
This would allow me to remove one by one, test the page and it it wasn't the correct URL at first try, go back, remove the white/blacklist each time.
It would make troubleshooting easier to get a feature on a page working again.
It would make finding the source of the ad on a page easier.
