I don't know whether you have used the History sidebar (Ctrl+h opens and closes it) but you can open that in a tab by pasting the following in the address bar and pressing Enter:

chrome://browser/content/history/history-panel.xul

Does that work the way you'd like? Since it's so long, it's probably easiest to bookmark it...

Or if you would like the multi-column listing of the Library dialog ("Show All History") you could try this:

chrome://browser/content/places/places.xul

When I test that, it starts off with bookmarks and I have to switch to history.

BTW, I'm not sure it's safe to make edits when it's displayed in a tab...

Yep! :) That's what I needed. Still weird I have to use Chrome for it.

The reason I needed this is because I'm making a custom startpage for my Firefox.

One big form in the middle which acts as Search-bar, URL-bar and now also to get Firefox pages. :)

Firefox uses the "chrome://" protocol to access its own internal files and also access files from extensions (no connection with Google Chrome).

Note that you can bookmark such chrome URI pages for easy access.
