[Firefox 4] tab bar width decreases when RequestPolicy toolbar button pressed about treestyletab HOT 2 CLOSED

Thanks. This commit solves the conflict: 93ab502

Because TST requires a custom binding for the tab toolbar, TST includes some CSS rules to override Firefox's CSS itself ( http://mxr.mozilla.org/mozilla-central/source/browser/themes/winstripe/browser/browser-aero.css#202 ) The Firefox's rules has ":last-child" pseudo class, so I also added it to my rules. However, Request Policy dynamically inserts a menupopup into the toolbox as the last child. Then TST's custom CSS rules are momentarily-lost. This is the reason of this conflict.

The commit re-defines TST's CSS rules with ":not(:last-child)" pseudo class. In the next release, TST always apply its custom rules even if Request Policy insert a menupopup into the toolbox.

By the way, I think the toolbox is not a good insertion point for menupopup. I think any dynamic menupopup should be inserted into the popupset#mainPopupSet...

Thank you for the very fast response and fix. I've also opened a RequestPolicy ticket for your suggestion of where the RequestPolicy menupopup should be inserted (https://www.requestpolicy.com/dev/ticket/188).
