Many web pages visited by Internet users have a wide variety of tracking tools embedded in them to collect data such as their behavior and things of interest.

In fact, enhanced tracking prevention can block a wide range of things, including 'social media trackers, ' ' cross-site cookies, ' ' tracking content, ' ' cryptocurrency mining, ' and ' fingerprint collection.'

On the page of Mozilla's bug tracking system Bugzilla referred to by Mr. Jakub G, there is a report that 'the button on the website does not work with the enhanced tracking prevention function turned on'. After investigating this issue, it was found that blocking Google Analytics with enhanced tracking prevention prevented the code that called the Google Analytics function from executing and failed to load the resource.
The solution was to 'replace Google Analytics with'non-functional fake Google Analytics' and run it.' By incorporating 'non-functional fake Google Analytics' into enhanced tracking prevention and running it on the website instead of normal Google Analytics, it is possible to keep the website displayed while preventing the collection of user data. It is said that it is.
About this report Internet users said, 'I think this is beautiful.' 'Marketers will sooner or later need to learn to adapt to a privacy-centric world.' 'This is great. Lazy Google. Due to the implementation of analytics, there are many websites that fail when blocked. '
