How to load tabs in Firefox on demand only?

Question

Browsers

I would like Firefox to load the contents of background tabs only after switching to each of them. It is desirable that this applies only to those tabs that have been restored from the last session. In fact, my tabs are bookmarks, and I would not want to change this concept, but the brakes are strained at the start.
