There are two levels to consider when talking about blocking (or disabling) DevTools in a browser:
- Disabling DevTools at the browser level. For example, if you have a browser for web development, and another one for personal browsing, you may want to disable DevTools in the latter. Maybe because you don't want F12 to open DevTools. Or maybe it's your mum's browser and she always gets confused when she accidentally opens DevTools.
- Disabling DevTools for an entire organization. For example, you're a teacher and you don't want your students to be able to use DevTools. Or your an IT admin and you want to disable DevTools for all the computers in your company.
All browsers have different ways to disable DevTools. Here are the ones we currently know about. If you know of others, please let us know on the DevTools Tips GitHub repo.
