Enhance privacy by automatically deleting DOM storage/IndexedDB super-cookies

Features & Capabilities

StoragErazor is a Firefox extension designed to boost your online privacy by automatically deleting DOM Storage (local storage) and IndexedDB data—often used as super-cookies for tracking—every time you restart your browser. It selectively removes only those IndexedDB databases created by websites, leaving addon databases untouched.

In addition to automatic cleaning upon restart, StoragErazor offers a handy browser action menu to manually erase these stored databases whenever you want. Compatible with Firefox version 57 (57.0b3 or higher), it ensures users can maintain better control over their tracking data, providing a practical solution against persistent super-cookies without complex configurations.

User Reviews

Using this was a long shot, since it's old and has few users, but I hoped it might do what I'm looking for. But no. I does not delete data stored in DOM storage or IndexedDB. Maybe the developer will see this and update it. One can only hope ....

Clearing "Cookies and Site Data" in Firefox Settings left a long list of sites with "0" in the Cookies column, but non-zero "Storage." StoragErazor erased the Storage data (local storage) for all those sites.

Is StoragErazor 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.

StoragErazor requires very minimum permissions.

Risk impact analysis details

Medium Enables sending notifications which can be spammed but have minimal direct security impact.

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.

StoragErazor has earned a fairly good reputation and likely can be trusted.
