The Trusted sites pane lists all the trusted site directives. The purpose of a trusted site directive is to tell on which page uBlock Origin (uBO) should disable itself completely. When uBO is disabled on a page, there will be no filtering applied to that page.
When uBO is disabled for a site, its toolbar icon will be grayed, and the large blue "power" button in the popup panel is dimmed.
When you visit a web page, uBO will try to match the URL of the page in the address bar against the existing trusted site directives. When there is a match, uBO will be disabled for that page.
The easiest way to create a trusted site directive is by toggling the large "power" button in uBO's popup panel -- this will cause a site-wide trusted site directive for the current site to be automatically created and added to the Trusted sites pane.
The Trusted sites pane allows you to review or edit the existing trusted site directives, or to manually add new ones.
Important: read carefully
There are predefined trusted site directives when you first install uBO:
chrome-extension-scheme
moz-extension-scheme
[!CAUTION] You should not remove these predefined trusted site directives, unless you know exactly the consequences of doing so.
Removing the predefined trusted site directives without understanding the consequences could cause your browser to malfunction.
Obsolete, no longer used directives.
Removed in 1.56.1b1:
about-scheme
chrome-scheme
edge-scheme
opera-scheme
vivaldi-scheme
wyciwyg-scheme
For Firefox Legacy platform, important directive behind-the-scene
is also in this predefined trusted sites list.
