I remember back in Firefox 2, I would be able to add a bookmark, and then when I clicked the bookmarks button, all my bookmarked pages would be displayed in a long list I would be able to scroll through. Since upgrading over the years, it seems that I can not reproduce that feature, but on another computer of mine, the bookmarks are shown in a very long list.

No bookmark addons are installed, this was an updated version from Firefox 3 and the effect seemed to of persisted through the updates.
