How to develop a Chrome Extension to Scrape Emails ? | Chrome Extension Tutorial

If you know basic web development and JavaScript, then developing your own Chrome Extension is pretty simple. All you need to do is to follow the getting started guide provided by Google.
developer.chrome.com/docs/ext...
But, if you hate reading docs, then I have created this video which explains the steps you need to follow to build your own Chrome Extension. In this tutorial we are building an extension which would scrape emails from any webpage.

Thanks for this. I found a couple of other articles that were out of date or just plain too difficult to follow. The step by step guide with really clear instructions was exactly what I needed. A really awesome tutorial.

[@jamesseager3985]

[@jamesseager3985]

never mind, I've found that you only get that error whilst on a tab on Chrome:// or Edge:// such as the extensions page. any other website should be fine.

[@anshmishra1536]

@@jamesseager3985so basically what should I do ? Can u plz elaborate

[@shalinitripathi9811]

Same how can I resolve it

[@Sami-sg5os]

@@shalinitripathi9811 use this chrome.tabs.onUpdated.addListener(function(tabId, changeInfo, tab) { let emails = request.emails; alert(emails) //code in here will run every time a user goes onto a new tab, so you can insert your scripts into every new tab });
