Background:
I’m building a webextension that can be used on all browsers (Chrome, Edge, Safari, Firefox) which has the functionality to show a notification on all websites the users visits. Doing this I have used the content script to alter the active tab’s DOM/web content shown. The content script is written in TypeScript in React with the web extension tool wxt.dev using Ant Design for the notification to appear. The notification is a part of a warning to the users that the website visit contains content that is not allowed for children below 18 etc.
