User Reviews

Reviews are mixed: many users praise ease of use and desktop performance, but frequent donation prompts and tabs hijacking, plus inconsistent ad blocking on sites like YouTube or Twitch and privacy concerns, dampen the overall impression. Android support is missing, and some users report reporting issues. Overall, the add-on can work well for some, but reliability and UX disruption drive most complaints.

Pros

Easy to use and convenient.
Regarded by some users as one of the best desktop AdBlockers.
Supports site-specific blocking (disable ad-blocking on selected sites).
Generally performs well when it is functioning and has positive user sentiment.

Cons

Intrusive donation prompts and new-tab hijacking.
Inconsistent blocking on major sites (e.g., YouTube, Twitch) and not blocking all ads.
Privacy concerns / shady reputation of the company.
No Android version / not available on Android.
Difficulty reporting issues / lack of easy bug reporting.

Is AdBlock for Firefox 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.

AdBlock for Firefox requires a lot of 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 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.

AdBlock for Firefox has earned a fairly good reputation and likely can be trusted.
