Excellent.

This blocker works... And that's all. It's not the smallest of them all, and it definitely is not the easiest to use. Regex rules must be inserted one by one, with no way to save or restore the list. It's not practical the way it is, now. A better approach would be to use a textarea to edit the rules (one per line, for example), then the save/restore functions wouldn't be really necessary.

Is RegEx Blocklist 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.
RegEx Blocklist requires a few sensitive permissions. Exercise caution before installing.
Risk impact analysis details
- Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.
- High ****** *** ********* ** ******* *** ******* ******* ** ****** *** *** ******** ******
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.
RegEx Blocklist has earned a fairly good reputation and likely can be trusted.
