Redirect Blocker Chrome extension

This version of Redirect Blocker targets scripted redirects and popunder windows specifically, working silently from the moment it's installed. It's best for people who want protection against forced page jumps and hidden popunder tabs without touching any settings. The catch: it's narrowly focused on redirects and popunders, not general ads or trackers.

What this Redirect Blocker does

This extension specifically targets two behaviors: scripted redirects that send you to a new page without a click, and popunder windows that open silently behind your current tab. It runs automatically after install and doesn't interfere with links or buttons you actually click.

Redirect Blocker free vs paid

The extension is free with no listed paid tier. You install it once and it keeps working without any subscription or upgrade.

Is this Redirect Blocker safe?

To catch popunders and scripted redirects, it needs permission to monitor navigation events and new window or tab creation. It doesn't ask for an account or login. As with any navigation-monitoring extension, install it only from the official Chrome Web Store listing.

Redirect Blocker: FAQs

Is this Redirect Blocker free?

Yes, it's free to install with no subscription or paid tier.

Is Redirect Blocker safe to use?

It needs permission to monitor navigation and new windows to catch popunders and scripted redirects, which is what it's designed to do. Install it from the official Chrome Web Store listing.

How do I use Redirect Blocker?

Install it and pin it to your toolbar; it works silently in the background with no setup.

What's the difference between this and other redirect blockers?

This version specifically targets scripted redirects and popunder windows, while still letting your own clicks work normally.

What are Redirect Blocker alternatives?

Full ad-blocking and privacy extensions often include popunder and redirect blocking as part of a wider filter list.

Does Redirect Blocker block regular pop-up ads too?

Its stated focus is popunders and scripted redirects specifically, not all pop-up ad formats.

Does Redirect Blocker need an account?

No, there's no sign-up or login required.

Will Redirect Blocker block links I click myself?

No, it's built to let real, user-initiated clicks through and only stops automatic scripted redirects and popunders.

Can I customize what this Redirect Blocker catches through its settings?

Not really. Its listing describes no visible settings panel; it works silently right after install with no options to adjust. That keeps setup simple but means you can't fine-tune what gets caught.

What's a popunder, and how is it different from a regular pop-up?

A popunder opens behind your active tab, so you often don't notice it until you close your windows, unlike a pop-up that appears on top. This Redirect Blocker specifically targets popunders and scripted redirects, not front-facing pop-ups.
