Tabs Bar Minimal Size

Install

Keep the Tabs Bar Size to a Readable Minimum Size. The purpose of a browser is to read web content not to lose valuable real estate for content you already know what it says. Along the lines of providing more space see my other styles as well.

//Warning: Along with the install for my Tabs Bar Minimal Size style in the green box to right is a drive-by install for "New Tab King", I do not approve of it, and it is against everything that I try to do to improve tab usage.
http://en.wikipedia.org/wiki/Drive-by_install (def. 1, 2). End of Warning Message.//

The tool tips (#content spacer), and the tabs drop down (#content stack[pack=end]) are left intact where one can see the full tab names. If Fx 3.6 destroys tabs drop down you may be forced to use "Tabs Menu" extension (addon/1242).

The curved appearance of tabs could be completely removed (flattened), as seen in Tabs: Remove Tab Bar Background (Windows).
.tabbrowser-tabs {-moz-appearance: none !important; background-color: transparent !important; background-image: none !important;}

For best viewing of the Before and After pictures install my userstyles.org -downsize screenshots to fit window (12373), so you will be viewing actual sizes if your window is at least 510px wide. The actual images are life-size images grabbed from the screen before 409x32px and after as 410x18px showing a reduction to 56% of the original height, and as you can see more of the wording appears in the same width.

This is a companion for Tab Color Underscoring active/read/unread (9023) by David McRitchie, which shows active tab with red underscore, previously viewed with blue underscore, and unread with a green underscore. Styles I use can be seen at http://kb.mozillazine.org/User:Dmcritchie

Removing the New tab button from tabs bar added by Fx 3.5, suggest you drag New Tab button from customize so you can have it on one of the other toolbars again. (hiding tabs newtab button is now implemented into this style)
/* Hide the tab container's New Tab button */
.tabs-newtab-button { display: none !important; }

/* Remove left and right scroll buttons which appear at 70 tabs, and disappear
again at 68 tabs -- tabs get smaller and will never scroll with this setup */
.scrollbutton-up, .scrollbutton-down {display: none !important;}

Updates: (see code, browser.tabs.tabMinWidth must be set to 0 in about:config)
