So my issue was fixed, and I'm not sure how. I had lost my shit about my bookmark toolbar being empty, and having no bookmarks in the library. I had tried the "Restore Defaults" option, and on the surface it didn't seem to have any affect. So I completely closed the browser. I then remembered something I had to look up so I restarted Firefox and lo and behold there were my bookmarks.

So if anyone else has this issue I'd recommend restoring the defaults, close the browser and then re-open it. Maybe it will work, maybe it won't

That was very good work. Well done. Please flag your last post as Solved Problem so others will know.
