Parental control on Android

My project is a parental control that filters explicit content (pornography) and implementation of secure search in search engines. I already have the methods for such actions but I have found that at the time of navigation in any mobile browser the result is displayed in a new tab and the goal is to replace the content of that tab by the blocking page or by the result of the secure search.

The problem is that the result is creating it in a new tab and the objective is to update the content of that tab, or otherwise, it would close the tab and open a new one with the desired result

This is the method for filtering and safe search on Android.
