User Reviews
Users find Clear Cache useful for debugging and data clearing, but report major reliability and safety issues. The most frequent concerns are that it sometimes clears data for all sites despite a current-tab option, forcing logins to reappear; it’s not reliable on some Firefox versions or Android; the extension popup is intrusive; and the defaults lack a safety confirmation, risking accidental data loss. These issues undermine trust despite its usefulness when it works. Pros
- Clears browser data (cache and cookies) effectively and as advertised.
- Very useful for web/extension development and troubleshooting.
- Does exactly what it says; aligns with user expectations when it works.
Cons
- Wipes data for all sites even when 'current tab' is selected; current-tab option is broken, leading to unintended data loss.
- Clears cookies/logins across many sites, causing the user to relogin.
- Not reliably functioning on some Firefox versions and is unavailable on Android.
- Pop-up window appears on extension click and lacks an auto-close option.
- Aggressive default behavior with no confirmation prompt, risking accidental data loss.

Is Clear Cache 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.
Clear Cache requires a few sensitive permissions. Exercise caution before installing.
Risk impact analysis details
- Critical Grants access to browser tabs, which can be used to track user browsing habits and history, presenting a privacy concern.
- Medium ******* ******* ************* ***** *** ** ******* *** **** ******* ****** ******** *******
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.
Clear Cache has earned a good reputation and can be trusted.
