the site "" is an example of a site that detects if you are using a blocker.

it would be nice if adblock could block detector scripts

maybe bake the anti adblock code into the binary so sites cant detect by not using standard user agents so the site is unable to detect adblock.

    Neither AdBlock nor Adblock Plus nor uBlock uses any sort of "binary": It's all Javascript.

    What anti-Adblock measures do is check whether certain content failed to load or whether certain HTML elements are hidden when they shouldn't be; sites can't directly tell whether AdBlock or anything similar is in use, just whether content was blocked (this means that even if you use something else, like a special HOSTS file or PAC file, you can trigger an anti-Adblock message).

    Usually, sites use third-party scripts for anti-Adblock measures, and they can themselves be blocked; other times, they test for the presence of dummy scripts or HTML elements, and those can just be whitelisted.

    One well maintained subscription that does just that is the Adblock Warning Removal List:

    If you want a more thorough anti-Adblock solution, use Reek's subscription in conjunction with his UserScript:

    Not all anti-Adblock methods can be defeated, however: Just look around any discussion of Hulu, which relies on plugin content that has more capability than mere Javascript to defeat efforts to block the ads while still viewing the content.

    if there is no binary then why is it when i open adblock(s) in a text editor i get junk that looks like a binary instead of plain text javascript?

    Hi ejonesss,

    AdBlock's code is JavaScript with some HTML, CSS, and so on. It's not compiled. Even the .crx and .safariextz files are only compressed files. If you unzip them with your favorite archive program, you'll see the same contents as on

    What file are you trying to open in what text editor?

    wrong i just located the extension and it is a binary not a package or folder here i have attached it so you can see for your self

    if your email does not allow attachments then open the following path


    in the finder command shift g go to folder and enter above path and right click on the extension you will see there is no option to open package witch means it is not a package it is a compiled binary

    Hi ejonesss,

    Well, no, they have to be unpacked first. The Chrome and Safari installers do this on the fly.

    no i meant if i unzip them can i simply re zip them and they will will install after then renaming from zip to their proper name?

    i think i can modify the code to make it be able to get around the limitation in safari..

    i see in the extension builder i have to get a developer certificate and after looking on the despite that you can make extensions for free they charge $99 for the certificate.

    Hi Ejonesss!

    Getting back on to the reason you made this discussion, does enabling the AdBlock Warning Removal list do anything? I went to Hackintosh Zone once (I was attempting to make a VM for testing purposes) but gave in to the message, rather than trying to enable the list.

    You can enable the Warning Removal list at AdBlock button -> Options -> FILTER LISTS. Just check the checkbox and reload the page and let us know if it works!
