You would bookmark it using the Star button in the address bar like any other webpage. You can also right-click on the tab that is displaying the PDF and select Bookmark Tab.

The menu you are looking at is just to deal with the PDF document itself.

If you just want to bookmark the beginning of the document, you use the same method as a web page.

If you want to bookmark, say, page 4, there are two options:

(1) Expand the left column and scroll down to the thumbnail for page 4

Option A:

(2) Right-click the thumbnail and choose Bookmark Link...

(3) Add a relevant title (Firefox doesn't pre-fill the page title) and save

Option B:

(2) Right-click the thumbnail and choose Open Link in New Tab

(3) If Firefox didn't switch to the new tab, switch to the new tab

(4) Add a bookmark to the page normally (in this case, Firefox pre-fills the title)

Thanks for the suggestions, they worked obviously. It's just that I remember about a command in the pdf toolbar, it must have been deprecated or something like that.

Thank you again!

Actually, there is an entry I never noticed before called Current Page that updates the URL for bookmarking purposes but doesn't actually create the bookmark. It also adds some zoom level info to the URL, which is interesting.

Note that "Current Page" (View URL from Current Page) is a link and you can right-click this menu item to find "Bookmark Link" in the context menu.
