Even with existing bookmarks scrolling through the directory structure is tedious and error-prone
It'd be nice if such bookmarks were "default", and closing the tab would remove it from the set of "bookmarks", idk
Latest Firefox is expressly optimised for opening tabs.
See e.g. http://www.zdnet.com/article/firefox-can-open-over-1500-tabs-in-15-seconds/

Even so, it's still 15 seconds every start-up, that the browser is unresponsive - and this rate scales further, such as my case of (yes, really) 4000 tabs, which took 40 seconds of waiting per boot-up
Factoring in the additional memory footprint savings, this leaves a clear advantage to not have a bajillion tabs open - not to mention that the current means of searching and browsing through many opened tabs is fairly limited, to only the tab slider arrows on the left and right of the toolbar

The most important aspect of the "file manager" design I'm bouncing around in my headspace, is that it "keeps" the directory within your set of pages handy - so instead of having to renavigate the entire path each time you want to browse a page in that category, you get to stay there and pick whatever page you want
