Feature request: stealth mode

Some websites won't display anything when we use ad blockers. For those websites, we need a stealth mode so that AdBlock can do its work un-detected.

    Which websites do you see blocking AdBlock?

    It isn't really possible to run in a "stealth mode": The sites you're talking about probably detect situations usually caused by ad-blocking, like hidden HTML elements, or scripts or images that failed to load, and then conclude that the user was using an ad-blocker; all that can be done is to see, on a case-by-case basis, just what the sites are detecting, and then modify filters or add whitelists to fool the anti-adblock detection.

    The goal is to unblock as little as possible to allow the site to still be usable; some particularly naïve implementations actually check for a file that, when loaded, does nothing anyway, so unblocking it doesn't let any ads go through (I think Twitch does that).

    By the way, this is actually the sort of thing that the maintainers of EasyList, the most important subscription, do on a regular basis when they get problem reports, and that (along with general issues involving sites breaking when general filters are used) is why EasyList has so many whitelist rules.
