Why do my bookmarks open in a sidebar rather than a tab?
Every time I select a bookmark from the bookmark toolbar a sidebar opens with my bookmarkselection rather than a tab or window.

Right-click (or control-click) on the bookmark and choose Properties, then uncheck the setting "Load this bookmark in the sidebar".
Using JavaScript buttons on web pages for "Bookmark this Page" causes that preference to be selected when saving the bookmark in that manner. So, don't use those buttons, use the "Bookmark this Page" feature that is built into Firefox instead.
