It is recommended to switch to a new clean profile (or at least delete 'localstore.rdf' from profile folder) to avoid UI issues after upgrading from Firefox 28 (and older) to Firefox 29 (and newer).
This add-on restores squared tabs, appbutton/appmenu (known from Firefox for Windows), bookmarks menu button, bookmarks sidebar button, history sidebar button and other buttons from Firefox 4-28 (non-Australis) on Firefox 29+ (Austalis UI - Windows, MacOSX, Linux). All buttons are fully optional. Some of them have to be moved to toolbars manually using browsers 'customize' area.

Squared tabsClassic tabs option replaces 'curved default tabs' with 'squared classic tabs'.
Tabs on MacOSX look more like Windows tabs with MacOSX colors than previous Mac tabs.
Australis tabs (experimental, Windows Aero only)Squared classic tabs colors combined with curved tabs.
Tabs 'not' on topSimulates the removed 'tabs.onTop=false' setting from about:config and places tabs below navigation toolbar. On MacOSX these tabs have reverse appearance like on pre-Australis builds.
Application button / application menu settingsApplication menu titlebar button [Windows only]The appmenu titlebar button is fixed on titlebars left side like on it was since Fx 4. It is enabled by default on Windows systems.
Application menu toolbar buttonThe appmenu toolbar button is a default toolbar menu button and can be placed on any available toolbar.
If it is moved to tabs toolbar while the menubar is disabled, the appbutton appears on browsers titlebar (Windows only). Otherwise it appears like a default toolbar button placed on any toolbar.
Application button colorsOn tabs toolbar and on titlebar the appbutton can be colored orange, blue (Aurora), black (Nightly), transparent, blue (Palemoon), red, green and gray [in normal browsing mode] and purple [in private browsing mode] like on previous Windows browser versions.
NoteThe new appmenu is not an exact copy of the old one, but looks as original as possible. Some elements like 'splitmenu' are not available in Firefox Australis anymore, so menuitem and a submenu are placed in a row now. The appmenu also misses some non-cloneable menuitems inside developer- and options submenus.
Small nav-bar buttonsNavigation toolbar buttons get alternative margins and paddings to simulate small icon view.
Hide 'Navigation Toolbar'Hiding nav-bar might be interesting after its items get moved to other toolbars.
'Add-on Bar'A toolbar at windows bottom simulates the 'old' add-on bar. All movable buttons and items can be placed on it. Add-on bar can be accessed through toolbars context menu (right-click on an existing toolbar) or can be toggled using 'Ctrl+/' (Windows/Linux) btw. 'Cmd+/' (MacOSX).
'Additional Toolbar'Another toolbar below top toolbars, where buttons and items can be moved to. It can be accessed through toolbars context menu (right-click on an existing toolbar).
Findbar on top or at the bottomForces findbar to be displayed on top or at the bottom.
Icons + textDisplay text below toolbar buttons.
Text onlyReplace toolbar button icons with text.
Bookmarks menu buttonThe bookmarks menu button is a default 'toolbar menu button'. On personal toolbar its label and icon are visible.
Bookmarks sidebar buttonThe bookmarks sidebar button toggles the bookmarks sidebar.
History sidebar buttonThe history sidebar button toggles the history sidebar.
Back-forward, reload and stop buttonsBrowsers default buttons got merged with urlbar and cannot be moved to different toolbar positions or to different toolbars. CTB recreates these buttons.
Combined reload-stop buttonPlace stop and reload buttons in that order on any toolbar and enable the corresponding option on CTRs preference window. Hover the option on options window to get extra information.
Toolbar: [something]...[stop-button][reload-button]...[something]
Spaces and flexible spacesA couple of toolbar items simulate spaces and flexible spaces. They can be moved to toolbars like toolbar buttons using browsers customize menu.
Windows - Linux - MacOSXThis add-on was tested on Windows 7 (AeroBasic, AeroGlass, Classic) & 8 & XP (Classic, Luna-Blue/Silver/Olive, Zune, Royale), Linux Mint KDE, Ubuntu and MacOSX 10.8/10.9. On other Systems or non OS-default themes tab colors may look wrong. Bookmarks, history, stop, reload, back and forward toolbar buttons use default OS icons (Firefox Windows icons on Windows systems, Firefox Mac icons on MacOSX and Firefox Linux icons on Linux systems).
Known 'issues'/'glitches'/extra info1) Application menus 'cut', 'copy' and 'paste' buttons do not always work like they should.
2) Switching between AeroGlass and AeroBasic on Windows 7/Vista can change application buttons position, if the menubar is disabled. Maximizing/restoring browsers main window or restarting Firefox reslves the problem. This glitch is caused by MS Windows and titlebars behavior and not by this add-on.
3) Tab colors on MacOSX fit to current ui instead of using pre-Australis colors. This is intended and not a bug.
Notes1) Do not install this add-on on pre-Australis Firefox (4-28). It is not intended to be used with older versions and will certainly break some parts of the UI or not work correctly at all.
2) This add-on was made for browsers
default theme and will certainly break parts of the UI especially tabs, if used along with Firefox themes or Personas, but additional buttons and their options could work fine (untested!).
