Some more firefox about: commands

So, after my last post on this topic, some friends pointed out a couple of more useful commands. I thought I should share it here.

about:permissions
This command shows the permissions given by you to different websites, like allowing to store passwords, share your location, allow cookies, open pop-up windows, and maintain offline storage. This was added recently in Firefox 6, so it might not work for you if you are using an older version. Here's a screenshot:
Firefox about:permssions
about:about
This is the meta about page - the about page of about pages. It lists all the about page available to you (except, of course, the Easter eggs). Another screenshot:
Firefox about:about
about:compartments
Mozilla has added this new command in the latest nightly build of Firefox 13. This page shows a list of all running JS compartments. Compartments are little segments of memory which is used by JavaScripts in Mozilla Firefox. Check this link to know more.

about:compartments
Firefox about:compartments

about:healthreport
Firefox 21 has added a new "health report" page that provide a graphical representation of your browser's performance, along with average startup times, monthly running time for the application (in minutes), monthly number of crashes, and total number of bookmarks, add-ons and plug-ins.

Firefox about:healthreport


about:telemetry
Opens a page that shows the information about performance, hardware, usage and customizations collected by Firefox's telemetry. This information can optionally be submitted to Mozilla to help improve Firefox.

Thanks for Sagar and Agni for their inputs. And, as always, if you come across any more interesting stuff about Firefox, please let me know.

    chrome://browser/content/

    Opens gives you sort of subtabs, but that doesn't work that way!
