Plain Old Favorites - Global installation - Why not supported?

Question

Using Windows XP.
Since you have adopted your "aggressive release cycle" approach, with every upgade to FireFox, you have broken compatibility with the "Plain Old Favorites" extension.
In the Version 3 releases, all I had to do was add the contents of a locally installed extension into the global "Mozilla FireFox/extensions" folder and the extension was inherited by all users.
Since then it appears that I have to separately install any new add-ons on a per-user basis, which is a real pain. Tell me this isn't so. This has implications for any corporate installers as well.
Why lack of Firefox support for "Plain Old Favorites" and the programmer maintaining it? I would have thought it should be a default plugin for Windows users so that FireFox can integrate with the Windows Task Bar "Favorites" extension.
It is much easier to to provide a link to Favorites in your "Start Menu" bar than use FireFox Bookmarks.

hello brianleetamau, please see http://mike.kaply.com/2013/05/13/more-major-changes-coming-in-firefox-21/ about the way to install extensions globally.
regarding the compatibility of the "Plain Old Favorites" extension: please try if you can get it to work with version 1.4 of the extension which is available at https://addons.mozilla.org/firefox/addon/plainoldfavorites/versions/?page=1#version-1.4 or else please try contacting the author of the addon.
