By default, the Cookie Manager opens when the extension starts up. This allows you to keep the extension disabled until you need it.

You can also turn off the automatic opening, and manually open the cookie manager by clicking on the extension button in the toolbar (desktop) or the Cookie Manager menu item.

There are lots of bugs in Firefox around private browsing cookies, with the majority being fixed in Firefox 58. The extension attempts to work around every bug where possible. For details, see https://github.com/Rob--W/cookie-manager#browser-specific-notes
The bug that affects most users is that in Firefox 55 and earlier, private browsing cookies can only be set when the cookie manager is opened from a private browsing tab. If you try to edit a private browsing cookie of a site on the Tracking protection blocklist, then you must temporarily disable Tracking protection, via the "Tracking protection" checkbox at Settings > Privacy.
