Some of the best free ad blockers for browsers you can use in 2023 are: 1. There are tons and tons of ad-blockers out there that you can easily use as an add-on with most modern browsers, but the list below consists of some of the best tools for taking care of the menace that is a pop-up advertisement. It’s up to you whether you want to apologize to the guy or not, but if you frequent websites that rain down a barrage of ads to visitors, at least show yourself some mercy and use a free ad-blocker service. Pop-ups are so universally hated that even the guy who invented these (Ethan Zuckerman) apologized to the world for this mess. Yeah, you all know what I’m talking about. You know, when you’re watching stuff and a bizarre ad comes out of nowhere to get plastered on your screen? ![]() ![]() It's a big list, though, and it can change at any time.There is perhaps nothing more annoying in the world of the internet today than pop-up advertisements. You could just try and make sure your DOM elements never have IDs or classes that collide with any of those selectors. Adblockers generally use open blacklists of URIs and CSS selectors, like EasyList ( ) - this is what AdblockPlus uses and a fair few others. Your final choice is to try and avoid incurring Adblock's wrath in the first place. If it throws an error that looks suspicious (I think it's ERR_BLOCKED_BY_CLIENT on Chrome), then you show your warning message. The other option is to try and load a 'sacrificial file' - an image with a URI that looks like an advert, say - and then attach an onError handler to the element. To put it more simply: you can't use DOMMutationEvents to spy when a foreign extension messes with your page. The easiest way is to create a 'sacrificial element' - a div with a class like 'ad_unit', for example - add it to the DOM and then wait a frame to see if it has been hidden (with display: none, for example, or a getBoundingClientRect check).Įlement checking is tricky, though, because strictly speaking there's no guarantee an adblocker will run synchronously or before your checking code.īecause adblockers run in a privileged mode, their operation does not trigger events in the nonprivileged script space. They operate in their own separate thread, with a privileged API, and hidden from page scripts.ĭetecting adblockers is awkward. You cannot prevent Chrome extensions from running. So any solution that would actually prevent AdBlock from corrupting the site in the first place would be great. ![]() I mean, the site is a game, and this isn't the first time a browser extension has broken it, but I don't think first-time visitors would be too happy to see a popup asking to disable their blocker, you know? The only thing I can really think of is to detect AdBlock and pop up a small notice explaining that AdBlock is known to corrupt the website and that, since we don't run ads, they may want to disable it for the site. But if someone never knew there was a problem to begin with, I would actually lose traffic because of this. Now, I don't run ads and never plan to, so usually I just tell people with this problem to whitelist the site and all is well. Re-enable extensions one by one.įor some reason, it was blocking the links to the pages the user wanted to access. I recently had an issue whereby a user was complaining that they couldn't access a certain page because the link wasn't where it was supposed to be.Īfter some head-scratching, I had them disable all browser extensions and sure enough the problem went away.
