Installing an ad blocker in your browser is common these days. This is a big problem for companies that make a living from advertising, and they will try to prevent it at all costs. One of the clearest examples of large companies making a living from advertising is Google.
Google has one of the most used browsers in the world, and there are many blockers in its extension store. So… how do you go about preventing them from being used? The requirements for all of this are changed by restricting the use of ad blockers in the name of improving user safety.
Google implements various changes to Chrome that depend on any extensions developed using Manifest V3. The problem arises when many ad blockers are built with Manifest V2, which will soon be completely blocked. But there are other fundamental problems as well.
2024 is the date chosen by Google so that only Manifest V3 plugins will work in the browser, the rest will be left out. Until then, developers can update the plugin to accommodate these new rules, but the problem arises when many of them are abandoned and not supported. They stop working automatically.
Dynamic rules allowed for extensions are determined from this set of rules. With this change, 30,000 sets of dynamic rules are allowed in plugins, but the truth is that blockers like uBlock Origin work with 300,000 sets of dynamic rules to filter ads.
So all of these plugins have an important limitation, because Manifest V2 didn’t have a maximum limit for dynamic rules. According to experts, this is designed to compromise tracker protection, leaving users defenseless over their privacy. But Google says the opposite is true.
Many users are already considering switching to other browsers in case ad blockers stop working in Chrome. Firefox is one of the browsers that has announced that it will remain without restrictions on dynamic rules, so that blockers can be used without problems.
