If you want to prevent yourself from installing browser extensions at all, you might have considered if it’s possible to disable or block the extensions page on your web browser. Not only is it possible to do this, but there are other ways to further lock down a web browser.

It’s usually pretty easy to block the web store if you’ve installed a URL blocker. The two we are most familiar with, and have had the chance to test the most, are Cold Turkey and Freedom Blocker:

  • Freedom Blocker : Allows you to block both apps and websites on all major platforms. 
  • Cold Turkey Blocker : A solid, free option for windows and mac computers. There is a premium version, but the free tier is very generous.

In order to proceed with this guide, I’m going to assume that you’re using either Cold Turkey or Freedom Blocker.

Blocking the Browser Extensions Store Page on Cold Turkey

If you’ve successfully installed  Cold Turkey on your computer, it’s pretty easy to add a block for the extension’s store page.

Depending on which browser you use, there are different URLs you should add to your block.

For Google Chrome's webstore, add this URL to a blocklist:*

For the Microsoft Edge Add-ons store, add this URL:*

For Mozilla browsers, add this link to a blocklist to hide the add-ons store:


Make sure that you lock the block you've added these URLs to:

Instead of seeing the browser extension's store, you should see a blocked page:

Blocking the Browser Extensions Store Page with Freedom Blocker

In order to add the extension stores to a blocklist with Freedom, you will need to start a Freedom "session". We have more information about how to do this in our Freedom Blocker guide, if you’re interested.

Depending on which browser you use, you will need to use different URLs in order to block each web browser’s extension store page.

For Google Chrome's webstore, add this URL to a blocklist:

For the Microsoft Edge Add-ons store, add this URL:

Unfortunately, it's not possible to block the Mozilla Firefox extensions store this way.
