Firefox (and other browsers) have a special URI scheme to display
internal pages, or built-in functions. These commands start with an
"about:" followed something, for example - "about:blank" displays a
blank page.
These commands can be quite handy sometimes. For example, yesterday, I
was searching for how to use the "sync tabs" feature of Firefox 4
and 5. I knew how to enable tabs sync, but I did not know where I could
access the synced tabs. Of course, if I had just gone through the menu, I
would have found it under "History > Tabs from Other Computers".
But, Firefox 4 and 5 have their menu bars hidden by default, and so I
searched online and came upon another way to do that: just type
"about:sync-tabs" in the address bar (without quotes), and there are
your tabs.
So, I decided to find a list of all about: commands which can be used in
Firefox. And I found some easter eggs among them. Here are the commands
that I found to be working on my version of Firefox:
