Risk impact

Adblock Plus requires a lot of risky permissions and is not safe to use. Avoid installing this add-on unless you absolutely trust this publisher.

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, bypass your security settings, and access your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Risk likelihood

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

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, especially ones with higher risk impact and/or higher risk likelihood.

Пользуюсь приложением, сколько себя помню. Одно из самых полезных дополнений, а по-моему, даже обязательное.

Not easy to use; lacks essential features. For instance: when turned on it lets you block specific elements on a page but does not let you UNblock specific elements on a page. The app tells you that X number of elements are blocked but does not list them nor provide any way to see them to allow you to unblock them. This means the only way to see them is to disable AdBlock altogether on a given page, but then you cannot block specific elements anymore. There is supposedly a workaround involving developer tools but this is an extremely confusing rabbit hole that the uninitiated should not dare enter. It did not work for me and I only ended up getting even more frustrated. Even as a paying premium user I cannot solve this problem. I hope they fix this soon and give us the essential functionality of easily unblocking individual blocked elements on a page.

The manifest file declares the requirements and permissions that a Firefox add-on will have access to. By reviewing the manifest, you may be able to determine if a Firefox add-on is over-reaching (for example, if an extension is overriding your new tab page, or search provider, or requesting access to your web activities without any good reason).
