Followup on archived thread re Opening Bookmarks in Separate Window with FULL FUNCTIONALITY not Annoying Limits

Question

First, I find it annoying that relatively recent threads are closed so quickly, especially when good solutions aren't found to the questions posed.
In this case, I see someone else wanted to open their bookmarks in a new window, not a tab or sidebar.

The 'chosen' answer provided was use Ctrl Shift B. That does open the Library in a separate window.
But for me that's totally inadequate, because one can only view the contents of one folder at a time. And I have hundreds. The person posing the question replied that detailed information on each bookmark is not displayed that way either. In my case, with a large and developed bookmark tree, that telescoping two panel view poses an unworkable limitation. And one that kept me at FF 3.6.28 until a year ago, when I found an answer to that problem, and this gentleman's also, I believe.
I'm now using FF 27, with the All In One Sidebar extension. I believe that adds a Bookmarks Icon with a Star at the top of a new sidebar.
If set up properly (see customize), left clicking allows you to "display your bookmarks" as a Sidebar, New Tab or New Window. But more importantly, in the New Window at least, it is not in the dreaded two pane mode where I can only view the contents of a single selected folder at any one time. Instead, I can open multiple folders at one time and see multiple individual bookmarks, buried in separate folders or subfolders, at one time. Ie, the same hierarchical layout that used be available before FF 4 changed the whole bookmarks architecture. So, when I open a new folder to view its contents, it doesn't close the prior folder automatically. And that's the way it should be. Users should have options, not have particular behavior imposed on them. Now, I'm not confident that I can upgrade to a newer FF as I was not readily able to get the same functionality out of AIOS using a more recent version of FF. But I didn't try hard, so it might also work with newer versions. Perhaps someone can verify that.

This thread was closed so quickly? That thread is '''''just over a year old'''''. Threads get archived after 6 months, or later when the thread isn't "Solved" and receives new postings later on. And the Chosen Solution in that thread was to use '''chrome://browser/content/bookmarks/bookmarksPanel.xul''' in the URL bar (or a Bookmark).
As far as older versions of Firefox and how they worked, you are mistaken about how Firefox 3.6.xx works - basically the same as the later versions all the way up the the current Firefox 35 Release version. In the Library window ''(Show All Bookmarks)'', select a folder in the left pane and view the contents of that folder in the right pane - is the same now as it was in Firefox 3.0, with few minor changes.
The last version that had the old Bookmarks Manager window, where you could have multiple folders open in the right pane was Firefox 2.0.0.20. Firefox 3.0 was the first version that had the current Library window scheme. Firefox 3.0 was where the major change to the Show All Bookmarks occurred.''The reason that I am so sure of when those changes occurred is that I have every version of Firefox from 2.0.0.20 all the way up to the current Nightly 38.0a1 version installed; I didn't rely on my memory of those old version changes - I just viewed them to answer this thread.''
Regardless of how each individual user thinks Firefox "should work", it works they way Mozilla decided it should work. If you don't like the way the standard features work you can always install extensions that do have the features you want. Mozilla doesn't impose anything on their users; don't like something find an extension that does it better for you. And it an extension doesn't exist; learn to create those features yourself by building your own extension. Still not good enough; use a different browser that works the way you think it should work.
As far as updating to Firefox 35 goes, use the Firefox Portable version to experiment with, so you don't risk your current installation in case you don't like the new version.

Just install it to your hard drive; it won't affect your current installation in any way, shape, or form.
