"Quick Tabs" in Firefox

Internet Explorer 7 (IE7) for Windows XP+ only has been released in November 2006. Some have said the “Quick Tabs” is reason alone to use IE7.

Firefox already has had such a feature through add-ons:

*"Tab Catalog":https://addons.mozilla.org/firefox/1937/Catalog — https://addons.mozilla.org/firefox/1937/
Has an option to disable the viewing of the tab catalog on
button roll-over. The Tab Catalog button is a well-behaved
toolbar element and can be placed where desired on the toolbar(s).

Firefox Showcase — https://addons.mozilla.org/firefox/1810/
Very much like Quick Tabs.

Viamatic foXpose — https://addons.mozilla.org/firefox/1457/
Also, Very much like Quick Tabs.

Ctrl Tab Preview — https://addons.mozilla.org/firefox/2134/
A bit different. Has a very Mac OS X feel to it.

As with most Firefox extensions, many options are available for a given extension/add-on.

It has been said, “If you are not using Firefox extensions, you are not using Firefox”.
