User reviews

Bluhell Firewall is praised for effective ad and popup blocking, reducing Firefox's memory consumption, and providing strong, silent protection against dangerous sites. However, multiple users report significant issues, including high resource usage causing system freezes, blocking legitimate websites and OAuth transactions, and breaking site functionality. A common request is the addition of a whitelist feature to prevent blocking trusted sites. Despite these drawbacks, long-term users value its functionality when it's working properly.

Pros

Effectively blocks ads and popups, enhancing browsing experience.
Significantly reduces Firefox memory and resource usage.
Functions silently and quickly when working properly.
Offers strong filtering capabilities, including warnings about dangerous sites.
Has been reliable and functional for long-term users.

Cons

Causes high CPU and disk usage leading to browser and system freezes.
Blocks legitimate sites or transactions, including important OAuth logins and business-related websites.
Breaks functionality on some websites, requiring users to disable the add-on to regain access.
Lacks a whitelist feature to allow trusted sites automatically, leading to frequent need for manual adjustments.

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.

Bluhell Firewall 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.

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