The bookmarks disappear on a regular basis

  1. Suddenly, sometimes, I click on the Bookmarks menu and I don’t see them anymore (see the image in the original post). It’s empty.

  2. When I open the Bookmark Manager tab, I see the Bookmarks. There’re there.

  3. The only solution I found to bring them back in the menu: restart the Browser.

  4. After that, it’s OK, they’re back in the menu, but some days later, I go back to the point #1.
