Status bar removed from Firefox beginning with version 4.0b7
Beginning with Firefox 4.0b7, the status bar has been removed (http://support.mozilla.com/en-US/questions/764307). There is no option to make the status bar available, as suggested by http://www.zotero.org/support/kb/no_status_bar_icon . Instead, there is a new 'Add-on' toolbar, which can be activated through the usual View -> Toolbars menu. The Zotero icon now lives in this 'Add-on' toolbar. One problem with this new behavior is that the Zotero icon now takes up an entire horizontal menu bar, which serves no other purpose and is hidden by default.
One can customize the other toolbars and add the Zotero 'Z' icon. If Firefox decides to permanently do away with the status bar at the bottom of the window, perhaps having a Zotero icon installed on one of the upper toolbars should be the default behavior for future Zotero installs on Firefox 4. This would fit better with Firefox's new style moving forward and avoid confusion from new users who are not able to find the 'Add-on' toolbar, which is hidden by default.

One thing I have noticed is that the status bar shim isn't movable like the rest of the add-on bar contents, which is another reason for Zotero to switch to using the add-on bar natively. It may be a little tricky to support both the status bar (for Fx3.6) and the add-on bar (for Fx4), but we're planning to look into doing so in a future Zotero 2.1 beta.
To clarify my comment about the Zotero icon taking up an entire horizontal tool bar:
For me, the only icon in the add-on bar is the Zotero icon. The Zotero icon only takes up the width of the icon, but the Add-on bar takes up the width of the window. If not for the Zotero icon, I would have no need for the add-on toolbar. Thus, the Zotero icon necessitates an almost empty gray toolbar at the bottom of the window. Screen real-estate would be conserved by moving the Zotero icon to an upper toolbar. Of course, this can be easily done through customization. I just humbly ask us to consider whether having a Zotero icon in the add-on toolbar is superior to having a Zotero icon in an upper toolbar. At the moment, having the icon in the add on toolbar is confusing, as the add on toolbar is hidden by default. Also, a single icon necessitates an entire horizontal toolbar, which is particularly noticeable for laptop users with limited screen real-estate. That all said, perhaps others have a better understanding of the benefits of the add on toolbar and how the Firefox team envisages the add on tool bar benefitting add ons like Zotero.
(For what it's worth, I find the removal of the status bar to be a terrible change, and I'm using Status-4-Evar to restore the previous functionality.)
