adBlocker domain exceptions should not strip out www subdomain

  • There are some sites for which the www subdomain is not merely an alias for the base domain, and where you may wish to whitelist the www subdomain without whitelisting all subdomains.

    My specific use-case involves Tumblr: I had whitelisted uBlock Origin on (where the user's posting interface lives, but where no public Tumblr page lives, all of them being on separate subdomains of, because it was running slowly and I wanted to keep as many extensions as possible from running there while I was trying to edit a post. I do not, however, want to whitelist my ad-blocker on every single Tumblr page, which is what whitelisting (without the www) would do; when I enter in the exceptions list, it is transformed to, and it should not be.

    I actually post to Tumblr very rarely, so I decided, instead, to just not whitelist Tumblr at all.

  • When you know that some sites have www1,www2, .... then you can consider it similar to subdomains or different domains.
    For example Ideal Zanussi Maintenance in Alexandria is similar to Zanussi Maintenance in Alexandria but both fitched from different servers.
    So i agree completely with you. 🙂
