The matrix toolbar

The scope selector

The scope selector let you choose where the rules you create apply, or where they are removed from. There are three scope levels: global, domain-level, and site-level scope.

• Default is global scope: *. In global scope mode, rules apply to all web pages, except those which match a narrower scope.
• Other scopes:
  • Domain-level scope.
    • Example: https://*.google.com. Rules at domain-level scope will apply to web pages which match the scope, including the scheme (https or http), except if for web pages which match an even narrower scope.
  • Site-level scope.
    • Example: https://www.facebook.com. Rules at site-level scope will apply to web pages which match exactly the name of the scope, including the scheme.
• An example for the use of scopes: block facebook.com globally, but allow facebook.com when visiting https://www.facebook.com. This is useful to prevent those ubiquitous servers from tracking you, unless you explicitly visit them.
• Another example: to enforce the use of a secure scheme for a web site. If you create a scope https://www.google.com along with specific rules, these rules will not apply if the visited web page is http://www.google.com.

Padlock: for any changes to be permanent, you need to click the padlock.

• All changes in the matrix are temporary by default. This applies to scope selection as well.
• Don't be scared to experiment with whitelisting, blacklisting or graylisting. It's all temporary.
• When you are satisfied with the state of the matrix, make the scope/rules permanent by clicking the padlock.

Remove temporary rules from current matrix

Clicking this button will cause all temporary rules to be wiped out. Only the permanent rules will be active in the matrix.

Remove all temporary rules

• The web page will reload if needed when you close the popup menu, but you can force a reload while the popup menu is opened in order to see the effects of your changes.
