Incognito Blocker

This extension blocks incognito tabs. It must be allowed to run in incognito mode to work.

See the readme for instructions on allowing it to run in incognito:
https://github.com/brismuth/incognito-blocker/blob/master/README.md#allow-it-to-run-in-incognito

This extension is open source: https://github.com/brismuth/incognito-blocker

This is the entirety of the code that is running:

chrome.tabs.onCreated.addListener((tab)=>{
if (tab.incognito) {
chrome.tabs.remove(tab.id);
}
});
