By default Google Chrome disables your extensions for Incognito windows. This is in general a good practice since extensions can collect and store private data. However, it can be particularly irritating to not have an ad blocker enabled. Full-screen popups, flashing banner ads, "fake" links littered throughout a text document, and other horrors.

uBlock, AdBlock, and AdBlock Plus can be enabled for Incognito mode in this way.
