I am sharing a comprehensive guide on how to block pornography access with virtually no way of bypassing, for FREE.
The guide is hosted on this website: https://rentry.org/FreeLife
There is also a new Discord community for technical support about setup, but it's also a community about abstinence, Christianity, and self-improvement, please consider joining us: https://discord.com/invite/rWwRANc7TM
There is no affiliation involved or monetary incentive, it's all good will.
Also, on Linux and macOS, each browser has a policies.json file somewhere that you can edit to prevent disabling plugins, as well as to disable private mode, disable creating new profiles (which ignore plugins on other profiles), etc.
the discord is in the link bro.
