I have lots of bookmarks folders in my bookmarks menu, however recently they haven't been opening. If i hover over them it just shows a small square, and nothing happens if I click on them. However, I know that the bookmarsk are still there, because if I right click and choose open all in tabs, then the bookmarks in that folder will open. As well as this, I am also unable to create any new bookmarks - they show up if I open the Library, but not in my menu. Any help will be appreciated!
