What are content blockers

Content blockers are network or browser extensions that inhibit download of some material - or filter material as it is downloaded from the source. Content blockers bring a range of advantages; you improve overall speed when loading sites in Safari, and also enhance both privacy and security. The better content blockers have a ruleset that can be configured or modified to suit your particular needs.

Perhaps the best way to learn about Content Blockers - and how they work - is to take a look at one of the better options. One of the very best and most respected within the Apple App Store - designed for iPad, iPhone and Mac - is 1Blocker for Safari.

1Blocker is highly configurable - and crucially does not rely upon an external proxy-service of dubious provenance. All processing takes place on your device - and contrary to expectations, Safari will run faster and more efficiently. 

Unwanted content is not simply filtered after download (a technique used by basic/inferior products), but instead undesirable embedded content blocked form download. A further benefit on metered services, such as cellular connections where you data may be capped or chargeable, this not only improves speed but also saves you money. 

1Blocker has also recently introduced its new “Firewall” functions - that are explicitly designed to block “trackers”. Being implemented at the network-layer, this additional protection works across all Apps. Recent updates to 1Blocker has introduced additional network extensions, extending protection to other Apps.

About Content Blockers:

Typically, specs build in to software that avoids what is considered inappropriate, in some manor. So, setting up a device as a child's device, content blockers would apply here. Set up parental controls.
