User Reviews

Reviews consistently praise Adblock Plus for its strong ad-blocking performance and overall usefulness. It is viewed by many users as one of the best ad blockers and as a trusted, essential extension. The most recurring complaint across reviews is intrusive donation prompts and prompts to pay, which detract from the experience. A few reviews also mention isolated issues like outdated filter lists or performance slowdowns, but these are far less common than the donation-related concerns.

Pros

Strong ad-blocking effectiveness and reliability.
Very positive sentiment from users, with several calls that it's among the best ad blockers.
Widely regarded as an essential, trusted extension by multiple users.

Cons

Frequent donation/prompt popups asking for money, reported by several users.

I like the ads blocking. I wish it had a way to actively save the whitelist. I keep having to re whitelist things, with an import / export of the config files.

Is Adblock Plus 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 Plus requires a lot of sensitive permissions. 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.

Adblock Plus has earned a fairly good reputation and likely can be trusted.
