STRAIGHT ANSWERS

Before you add it.

No inflated promises. Here is what the free extension and Max Clean actually do.

Does JustBlock block ads, popups and trackers?

Yes. JustBlock uses bundled Manifest V3 request-filter rules to block selected ads and trackers, while Popup Guard helps stop automatic popups and popunders. It also cleans common tracking parameters from links and includes protection against known malware, phishing and unsafe sites. Results can vary as websites and filter rules change.

Do I have to pay for JustBlock?

No. Popup Guard, bundled request filters, trusted-site controls, link cleaning and live activity remain free. Max Clean is an optional $29.99/year subscription.

Does Max Clean accept cookies for me?

No. It hides matching banners without clicking consent buttons. Restore a hidden banner whenever you need to make a choice.

Will Max Clean clear every page?

It works on matching page elements, so results vary as websites change. If something useful disappears, restore it from the extension.

What does Focus Mode hide?

Choose YouTube Shorts, video recommendations, comments and supported home feeds on desktop YouTube, LinkedIn and Reddit. Search and the pages you deliberately open remain available. Timers, local-time weekly schedules and user-entered topic filters are included.

Does Privacy Mode remove my data?

Privacy Mode visually covers areas you select. It does not remove the underlying website data. Clean screenshots flatten selected visible mask areas into solid redactions; review the entire image before sharing.

Can I choose different settings for each website?

Yes. Override cleanup categories or pause an individual website. Saved blocks and masks can apply to a page path or the website. You can rename, disable or delete saved rules.

Is JustBlock antivirus software?

No. It uses bundled URL and domain filter rules plus Popup Guard. It does not scan downloaded files, remove malware from your computer or guarantee every unwanted request is blocked.

How do I manage a subscription?

Use Manage subscription in the extension to open Stripe's customer portal. Use the private restore code from your purchase to activate Max Clean on your other eligible browser installations.
