Features & Capabilities

When browsing the best seller lists this extension will tracks the books that it displays and the next time that item is in the list it will be hidden.

Reduces the number of times you see the same items in the Best Sellers listings.

Hides previously seen items - Automatically tracks and hides books previously seen on the lists
Filter by Ratings - Hide items below a minimum rating or rating count
Re-show after days - Optionally show items again after a set period
Separate tracking - Free and Paid lists tracked independently
Blocklist support - Import CSV of ASINs to permanently hide (for example, books already owned or previous read, etc.)
Configurable transparency - Choose how hidden items appear (25%-100% transparent or removed from list)
Dynamic content support - Filters items loaded during scrolling
Export/Import - Export / Import settings and item databases for backup / transfer to new computer or different browser
Privacy Respecting - All data is stored locally in your browser. There are no analytics collected.

You'll need to scroll down (and sometimes back up) for all of the items to load.

The extension page shows the counts of items visible and the total count of items. Not all pages have 50 items, so the total count may not hit 50.

Is AZ BS Filter Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

AZ BS Filter requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

AZ BS Filter is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
