User reviews

Users have experienced issues with Dr.Web LinkChecker failing to verify external links and causing persistent, annoying refresh pop-ups. It also struggles to block ads on some websites. While some praise its longevity and association with a reputable antivirus brand, significant privacy concerns exist due to its Russian origin. Overall, despite good intentions, the add-on's performance and privacy practices are questionable to many users.

Pros

Has been functional and reliable for some users over the years.
Developed by a reputable antivirus product company (Dr.Web).

Cons

Frequently fails to check external links, showing an error message that links cannot be verified.
Causes intrusive 'Refresh now' and 'Refresh later' pop-up banners on Firefox tabs, leading to user annoyance.
Does not effectively block ads on certain sites, such as e.mail.ru, even after manual blocking.
Concerns about privacy and data security due to it being a Russian product; some users fear it might collect personal information or act as spyware.

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.

Dr.Web LinkChecker 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 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.

Dr.Web LinkChecker has earned a fairly good reputation and likely can be trusted.
