 Hi,
 every time I want to edit a page, I get the pop-up "Welcome to Block
 Editor". (see here: [https://einstieg-in-wp.de/wp-
 content/uploads/2019/12/wordpress-531-block-editor-
 willkommen1-1536x731.jpg]) It's really getting on my nerves now. The pop-
 up appears only when I right-click the "Edit" link and select "Open link
 in new tab". I often practice right-clicking on "Open link in new tab",
 especially when I want to edit several posts one after the other from a
 search results list and don't want to miss anything.

 This incorrect behavior can be observed under Linux Mint in Firefox 75.0.
 In the Cromium Browser (Linux) the popup appears only the first time,
 after that not anymore, as expected. In Firefox / Mac the behaviour cannot
 be observed either. Only the Linux / Firefox combination is affected.
