User Reviews

Reviews are brief and mixed: multiple one‑word positive remarks and non‑English posts suggest international interest, but several entries are spammy or irrelevant and most reviews lack detail. Because feedback is sparse and inconsistent, it’s hard to judge functionality from these reviews alone.

Pros

Several reviewers give brief positive praise (e.g., "good", "ممتاز").
Appears to attract an international audience (multiple non‑English reviews).
Multiple short/concise reviews indicate some users have tried the add‑on.

Cons

Several reviews contain promotional links or unrelated content (spam/irrelevant).
Many reviews are extremely short and lack substantive feedback, making assessment difficult.
No consistent, repeated functional feedback about features or reliability across reviews.

Is Feature Queries Manager 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.

Feature Queries Manager 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.

Feature Queries Manager has earned a fairly good reputation and likely can be trusted.
