Bookmarks list disappears once a bookmark is selected

This relates to Firefox on Android. Not very long ago, when I wanted to look through my bookmarks and view some of them, I could get back to the bookmarks folder I was in straightaway. It effectively stayed open even after I clicked on the bookmarked page, and I could just minimise the bookmarked page and click on another bookmark to view. This no longer happens. So now when I want to view another bookmark, I have to go back to the bookmarks menu, navigate to the correct folder, scroll back down to where I was, and then select another bookmark. Which is beyond annoying. Why was this changed, and please can it be put back to how it was? Or is there another way to do this?
