Where did you had this red button?

You would normally access the bookmarks via the "Show your bookmarks" button next to the bookmarks star on the Navigation Toolbar.

It was a small red icon shaped like a bookmark, Since it is now missing, I can't tell you precisely where it was located, but it was to the right of the menu bar, about midway on the screen. The bookmark buttons on the navigation toolbar do not display all my bookmarks. I'm not a techie, so be patient with me.

You can check on the about:addons page (Firefox menu button/Tools > Add-ons > Extensions) whether any extensions are disabled because of the issues with signing that is forced on in the current release.
