Open incognito mode in the browser via a link - is it possible?

Question

Opera

Greetings
There are links in the bookmarks bar, or rather, one link, which is desirable to open in incognito mode and this is not an 18+ site. Is it possible to somehow add some data to the link or do something so that when clicking on this link, an incognito window with the site from the link automatically opens? Better yet, open, for example, a portable version of the browser with the necessary extensions.

Answer 1

For Firefox, this is solved by installing Custom Buttons and the corresponding code, which is taken from the Russian Mozilla forum, for example, or by asking them to write one in the same place.
Even easier - in the same place, a button on the panel with its bookmarks (stored not in bookmarks, but in its file, separately). You can add bookmarks with two clicks, and open them with two clicks (by clicking the button and selecting a bookmark). The code is easily corrected, you can open it even in a private tab (window), even in another browser, even in anything.
