Caveats

You can manually edit rules for per-site switches in the "My rules" pane in the dashboard.

There are no temporary vs. permanent settings for the per-site switches, any change to one or more switches will be immediately reflected in the permanent settings.

There are currently three per-site switches supported:

no-popups: To block all popups.
no-strict-blocking: To disable strict blocking.
no-cosmetic-filtering: To disable cosmetic filtering.

When toggled through the popup UI, these switches will apply only to the current web site. However you can edit them manually using the "My rules" pane in the dashboard.

The syntax is as follow:

switch-name: hostname state

The switch name must be followed by a column :, a space, then the hostname on which the switch must apply. Use * as a hostname placeholder to indicate you want the switch to apply everywhere. Following is the state of the switch, which can be on or off (true or false are also valid).

When switches share a common hostname ancestor, the most specific wins. For example, if you have:

no-popups: example.com on
no-popups: www.example.com off

and you visit www.example.com, the "no popups" switch will be turned off (popup allowed unless blocked by a static filter).

All switches are off by default, meaning there is no point in creating an entry such as:

no-popups: www.example.com off

Unless it is to override a related broader entry for which the switch is on.

Caveats

Chromium-based browsers: If you block popups everywhere by default (no-popups: * true), this will break "Open link in new tab" in the context menu. This is because of Chrome API limitations.
