Why does RetroTxt require Read and change all data permissions

RetroTxt add extension

The short answer is that it doesn't, which is a limitation of the web extension permissions. RetroTxt ignores all websites except those you tell it to monitor in the background.

If you're in a corporate environment or security conscious, after installation, you can fine-tune the browser to further lockdown RetroTxt.
