Where does the description on the Firefox start page come from?

Question

Search Engine Optimization

Hello. Faced such a problem. On the Firefox start page, which displays a list of previously visited pages, the meta description of the site page is gone.

At the same time, meta name="description" and even meta property="og:description" for this page ( https://cl.world/en/stocks) are filled.
Any guesses where FIrefox pulls the description from?

So it looks like this for me:
PS what went wrong I was too lazy to fix it ... the default is to display: none;
