Tabberwocky is a lightweight Firefox tab manager alternative of the popular Tab Mix Plus add-on. It offers popular options like protecting tabs from being closed, duplicate already open tabs, open new tabs next to the active tab and managing several other important aspects of tabs in Firefox.
The Firefox add-on will add several of its features (like protecting or duplicating tabs) automatically to the right-click menu when right-clicking on tabs in the tabbar in Firefox. Other features like opening tabs to the right of the current tab or switching to the last selected tab upon closing a tab are also activated right away.
Many of these features can be customized in the add-on's options. Here it is possible to disable context menu entries, change the behavior when opening or closing tabs, alter the design of the tabbar and configure the action when the backspace key is pressed in Firefox.
The backspace key can be configured to navigate back and forward or perform a page up or page down action. Tabberwocky does not offer all of the features of Tab Mix Plus yet. This includes the ability to display tabs in additional rows in the web browser or offering session management.
Not all users need that functionality on the other hand. Tabberwocky can be downloaded from the profile page at the Mozilla Firefox website.
Update: Tabberwocky has not been updated for a long time, to be precise since 2009, which is an indication that the author has abandoned the add-on. It is also likely that Firefox users running one of the latest versions of the browser will notice when they try to install and use the extension.
It is suggested to check out Tab Mix Plus instead, which is more than an alternative.
Update 2: Tabberwocky has been pulled from the Mozilla Add-ons store, it is no longer available. Use Tab Mix Plus instead.
