Firefox recently starts with an additional [- o x] window pane, will not load homepage on startup, and will no longer remember text sizes for websites.
Recently, Firefox no longer starts at my home page, despite that option in effect. Firefox no longer remembers the text size used the last time any given site was visited. Firefox allows one instance of customizing (right click in a blank tab area) then locks that option out and locks the menu bar, allowing only use of the orange drop down square. Adding or removing one of the toolbar options (right click in a blank tab area) removes the additional pane (minimize, maximize, close), but it returns each time Firefox is re-started.

I was able to resolve this problem, but only by completely clean re-instal of Firefox (all settings had to be dumped).
This was more of a work-around than a solution, but the problem is resolved.
