Firefox 3.6: Buildin Tab-Preview

Like ALT-TAB let's you quickly switch between your running apps, a pretty cool Firefox (V 3.6) feature enables tab-switching with preview!

I tend to keep my Firefox running for days without restarting, collecting numerous tabs...

Then I found this short post describing the setup - quite simple:

Just enter

about:config

in the address line and change two settings:

browser.allTabs.previews
browser.ctrlTab.previews

With Firefox 3.6.3 I only needed to toggle the first of these,
the second changed automatically...

Thanx, Timbob!
