uBlock's all and third-party deny modes block requests by default

Most content blockers use lists to determine what should be blocked and what should be loaded when a user makes a request.

Options to add custom filters are provided by many blocker extensions. If you are using the popular uBlock extension for example, you know that you can load and unload various network lists but also add your own custom rules that the extension follows to the letter.

The most recent development version of uBlock improves the extension's default deny blocking options by adding two new request types, all and third-party, to its list of options.

These options enable you to block (or allow) all requests of the selected type but with options to override the selection on a per-site basis.

The following default blocking options are provided, the two new types are highlighted.

  1. All - This works similar to how NoScript operates: don't allow anything to be loaded by default without user permission.
  2. Images - Allow or deny the loading of images.
  3. 3rd-party - This blocks third-party requests by default.
  4. inline, 1st-party or 3rd-party scripts - These three options block scripts that are loaded inline, from the same resource you are connected to or from third-party sites.
  5. 3rd-party frames - Blocks frames from third-party sites.

Setting it up

ublock default deny

The option to block 3rd-party requests and all requests has been added in the most recent development version.

You only get to those options after checking the advanced user setting in the options. Once you have checked the option, click on the uBlock icon and then on requests blocked to display the filtering options.

There you find general blocking options at the top and below that the list of domains requests. The status of each requests is highlighted as well and you can override it easily here if the need arises.

To disable third-party requests click on the red part next to 3rd-party by moving the mouse there. Once done, all third-party requests are blocked by default.

You can override the selection on a per-domain basis and may need to do so on sites that use these requests for part of their core functionality.

Some sites may use other domains to load contents from. Google for instance uses loads data from gstatic.com and googleusercontent.com when you connect to its properties. While some work fine without allowing those, others may block contents from working correctly.

The benefits of blocking third-party requests range from faster page loading times to improved privacy and better resource usage.

The only negative issue that may arise is that some websites may not work properly anymore once you enable it. This happens if they require contents from third-party sites to function. You can fix that easily though by enabling those requests individually.

While that means additional work, it ensures that requests are only made if they are required for the site's functionality.

      Well it is a bit difficulty to distinguish between name.com domains and files for instance.

    The comments section under this very article (3 comments) is identical to the comments section found under the following article:

    Not sure what the issue is, but have seen this issue under some other articles recently but did not report it back then.

    With the cloud, there is no such thing as unlimited storage or privacy. Stop relying on these tech scums. Purchase your own hardware and develop your own solutions.

      This is a certified reddit cringe moment. Hilarious how the article’s author tries to dress it up like it’s anything more than a png for doing the reddit corporation’s moderation work for free (or for bribes from companies and political groups)

    With Google Chrome, it’s only been 1,500 for some time now.

    Anyone who wants to force me in such a way into buying something that I can get elsewhere for free will certainly never see a single dime from my side. I don’t even know how stupid their marketing department is to impose these limits on users instead of offering a valuable product to the paying faction. But they don’t. Even if you pay, you get something that is also available for free elsewhere.

    The algorithm has also become less and less savvy in terms of e.g. English/German translations. It used to be that the bot could sort of sense what you were trying to say and put it into different colloquialisms, which was even fun because it was like, “I know what you’re trying to say here, how about…” Now it’s in parts too stupid to translate the simplest sentences correctly, and the suggestions it makes are at times as moronic as those made by Google Translations.

    If this is a deep-learning AI that learns from users’ translations and the phrases they choose most often – which, by the way, is a valuable, moneys worthwhile contribution of every free user to this project: They invest their time and texts, thereby providing the necessary data for the AI to do the thing as nicely as they brag about it in the first place – alas, the more unprofessional users discovered the translator, the worse the language of this deep-learning bot has become, the greater the aggregate of linguistically illiterate users has become, and the worse the language of this deep-learning bot has become, as it now learns the drivel of every Tom, Dick and Harry out there, which is why I now get their Mickey Mouse language as suggestions: the inane language of people who can barely spell the alphabet, it seems.

    And as a thank you for our time and effort in helping them and their AI learn, they’ve lowered the limit from what was once 5,000 to now 1,500…? A big “fuck off” from here for that! Not a brass farthing from me for this attitude and behaviour, not in a hundred years.
