Self-Destructing Cookies (WebEx) brings back effective cookie management to Firefox versions beyond 57, reviving the popular extension originally created by Ove. It offers two modes for cookie deletion:

Session Mode: Deletes cookies when all browser windows are closed.
Tabs Mode: Deletes cookies associated with a website once all tabs from that domain are closed, enhancing privacy per-tab.

For example, if logged into Gmail, session mode keeps you logged in until the browser is fully closed, while tabs mode logs you out as soon as all Gmail tabs are closed. Though it currently doesn't clear localStorage, future updates aim to add this feature. Perfect for users looking to prevent tracking and improve browser privacy seamlessly.

User reviews

Users appreciate that Self-Destructing Cookies effectively deletes cookies upon tab closure and offers simple operation with whitelist support. However, many report that it fails to clear cookies on browser shutdown and has limited management options. Despite some technical issues and inconsistent cookie removal after restarting Firefox, it remains a favored lightweight cookie-cleaning solution for enhanced privacy during browsing sessions.

Pros

Effectively deletes cookies when closing tabs, providing enhanced privacy.
Simple to use without complicated settings or configuration.
Allows adding exceptions or whitelisting sites for cookie retention.
Helps keep the browser cleaner by removing unwanted cookies.
Fulfills the basic need for automatic cookie deletion on tab close, making it useful for users seeking this functionality.

Cons

Does not reliably delete cookies when the entire browser is closed, despite claiming to do so.
Lacks sufficient options for cookie management, such as multiple whitelist categories or granular control.
Some users report that cookies remain after restarting the browser even when the extension is enabled.
Whitelisting functionality sometimes is not working as expected.
Occasional bugs or compatibility issues with specific Firefox versions or operating systems.

Recent reviews

Unfortunately it doesn't work at all. I can see all cookies in the cookie manager after a browser restart.

Extension safety

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.

Self-Destructing Cookies (WebEx) requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details

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 Browser Add-ons, 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.

Self-Destructing Cookies (WebEx) is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
