I have one more Firefox 3.6 about:config tip up my sleeve.  By toggling one setting, you can go from having a drop down list of tabs to a thumb-nailed view of each tab that is open.

Here is how you too can enable this secret Firefox 3.6 feature.

How to Enable the Tab Preview Menu Button

• Type about:config in the address bar. Then, if needed click the “I’ll be careful, I promise!” button.
• Next, in the filter box – type in:
  • browser.allTabs.previews
• Right-click that about:config entry, and select “Toggle”

This will change it from false, to true.  You could take the same steps to disable it too.  Now when you click that icon with the four tiny squares, you will get a visually prettier way to check out all your tabs.

Also once this has been enabled, you can use the keyboard combination:

Shift + Ctrl + Tab

To get the same tab previews, just without the button clicking.

about:logo — Displays the application logo (Mozilla Suite, SeaMonkey, and Firefox 3).

about:kitchensink — Was never included in Mozilla for the reasons listed in Bug 122411 (“Mozilla does not have a kitchen sink”). You can install an extension that adds it though :)

So what does Klaatu Barada Nikto mean? Shame on you – this is one any geek should know…

Congrats to the Firefox 3 team for making me giggle like an overly excited school girl over this nice little easter egg. (found via hint on foxiewire)

It was a lot of fun to read but one thing that really struck me as interesting was this about:mozilla “Easter Egg” that they mention. The Book of Mozilla has been something that even the first version of Netscape has had in it. You can pull it up in Firefox/Netscape by typing in about:mozilla into the Address Bar and pressing Enter.
