Tab Sidebar 2.5

The tab sidebar extension, if you havent heard of it already, provides a sidebar in the browser that can act as a replacement to the main tab bar, with extras.
The most obvious extra is that each tab includes a preview of the web page that is continually updated, but you also get navigation buttons for each tab.Since Tab Sidebar provides a replacement for the main tab bar, when the sidebar is visible, Firefoxs main tab bar will be hidden.
If you still wish to use the main tab bar then you can show it again from the Tab Sidebar options.

Main features:
- Provides navigation options for each tab including history, stop and reload.
- Allows you to move tabs around with drag and drop.
- You can drop links, local files and bookmarks anywhere you like in the tab list.
- Tab Sidebar displays the security status for your tabs.
- Automatically refreshes the tab preview whenever the page changes.
- Lets you hide the main tab bar when the sidebar is open.
- Bidirectional support making the sidebar work correctly in right-to-left languages.
- Works well with other tab-related extensions allowing you to use their context menu additions from the sidebar.
