In a web full of abusive scripts, this addon is a godsend.

must have in script-aggressive web 2-3.0

работает отлично

Enfin, cette extension semble faire disparaître ces fenêtres digiketa intempestives et énervantes !!!
Merci aux concepteurs :)

This addon is really nice, until recently. For whatever reason, it was completely reset on all my devices, so I am in the process of ADDING back all the custom setting and it is annoying... I almost uninstalled it.

Absolute necessity: it's the closest a user can get to controlling the execution flow of the browser without intervening at the source level, which would require someone to build the project from source

A recent change broke a website, and refreshing the extension didn't help.

good spyserver blocker

I think the user interface could use more work with limited options to change the appearance. It may help that you use a basic or general rule set on file, as you may be setting rules for things that are essential to browsing. You can only do this by importing a text file. This is a great extension for having more control to what is loaded into browsing.
