Useful addon
Is there a way to use larger lists?
The current version has a limit of about ~180 url's.
If I insert a larger list, it is not saved.
It also would be nice to be able to know when an addon is blocking a site (for example, changing the color of the addon icon or site favicon)
There is a small bug:
If I add a site to block, check it, then remove it from the list (i.e. the list is completely empty), the site is still blocked until I add a random entry to the list.

Is ReqBlock 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.
ReqBlock 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.
ReqBlock has earned a fairly good reputation and likely can be trusted.
