Controls and shortcuts

There are two places to control the extension: the toolbar icon, which switches filtering on or off for the site you are looking at, and the prompt that appears when a pop-up has been held back.

The toolbar icon

Clicking the icon toggles filtering for the site in the active tab. There is no menu to open — one click is the whole interaction.

Icon stateMeaning
Full colourFiltering is on for this site. Click to turn it off; the site is added to your allowed list and the page reloads so the change applies immediately.
Greyed outYou have allowed this site, so nothing is filtered on it. Click again to remove it from the allowed list and resume filtering.

Your allowed list is stored on your device and applies per site, so turning filtering off for one site leaves every other site untouched.

The pop-up prompt

When a page tries to open a pop-up, pop-under or redirect, the window is held back and a small prompt appears in the corner of the page naming the destination. From it you can let the pop-up through once, open it in a background tab so it does not take you away from what you are reading, or trust the site permanently so its pop-ups open without asking again. Dismiss the prompt and nothing opens.

Keyboard shortcuts

While the prompt is on screen, each choice has a key.

ShortcutAction
Alt + Shift + AAllow the held-back pop-up this once
Alt + Shift + BOpen it in a background tab
Alt + Shift + RFollow the destination in the current tab instead
Alt + Shift + TTrust this site, so its pop-ups open from now on
Alt + Shift + DDecline it and dismiss the prompt

On macOS use Control + Option in place of Alt + Shift. These keys belong to the prompt itself, so there is nothing to reassign at chrome://extensions/shortcuts.
