Features & Capabilities

BlockURL is a powerful Firefox extension designed to block specific URLs or pages, not just entire domains or subdomains.

With a user-friendly interface, BlockURL supports one-click blocking and offers import/export capabilities for managing custom block lists.

User Reviews

Unfortunately, this extension doesn't actually block the link (at least not in the same way ad blockers do). It just displays a pop-up window informing you that the page is blocked. In devtools->network, I still see the page's traffic after the blocking message. P.S. If this is helpful, the server can also be installed using the windows version of Python. However, you need to add DATABASE_PATH = path to the .db database to your environment variables.

Is BlockURL 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.

BlockURL 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.

BlockURL may not be trust-worthy. Avoid installing if possible unless you really trust this publisher.
