i think it’s called AdBlock, but websites wont allow you to access theirs unless you whitelist them.
AdBlock is similar to uBlock.
What I do in this situation is temporarily disable the adblocker to slip past the screen dimmer, then quickly re-enable it when the page starts loading, killing the secondary and tertiary ads. I use Pale Moon browser (a Firefox clone), with Adblock Latitude, which has a handy menu at the bottom of the screen.
