Reference for all "about"/"chrome" address bar strings for Firefox and Chrome

It there a reference for all the magic strings which one can type on Google Chrome and Firefox?

For instance I forgot how to create/show profiles in Chrome beta. I later found that it was about:flags. I am sure I can find more magic strings if I were to sift through code or plough through documentation.

But any reference here would be appreciated.

Answer

Google Chrome

In Google Chrome, it's either of these:

• about:about


• chrome://chrome-urls

The page will list all possible pages. In Chrome, all about: pages are internally treated as Chrome URLs, with the chrome:// protocol handler. Therefore, these are equivalent.

chrome://accessibility
chrome://appcache-internals
chrome://apps
chrome://blob-internals
chrome://bookmarks
chrome://cache
chrome://chrome
chrome://chrome-urls
chrome://components
chrome://copresence
chrome://crashes
chrome://credits
chrome://device-log
chrome://devices
chrome://dns
chrome://downloads
chrome://extensions
chrome://flags
chrome://flash
chrome://gcm-internals
chrome://gpu
chrome://help
chrome://histograms
chrome://history
chrome://indexeddb-internals
chrome://inspect
chrome://invalidations
chrome://linux-proxy-config
chrome://local-state
chrome://media-internals
chrome://memory
chrome://memory-internals
chrome://nacl
chrome://net-internals
chrome://newtab
chrome://omnibox
chrome://password-manager-internals
chrome://plugins
chrome://policy
chrome://predictors
chrome://print
chrome://profiler
chrome://quota-internals
chrome://sandbox
chrome://serviceworker-internals
chrome://settings
chrome://signin-internals
chrome://suggestions
chrome://sync-internals
chrome://system
chrome://terms
chrome://thumbnails
chrome://tracing
chrome://translate-internals
chrome://user-actions
chrome://version
chrome://view-http-cache
chrome://voicesearch
chrome://webrtc-internals
chrome://webrtc-logs

The following URLs are sectioned off because they cause something "bad" to happen:

chrome://badcastcrash
chrome://crash
chrome://crashdump
chrome://kill
chrome://hang
chrome://shorthang
chrome://gpuclean
chrome://gpucrash
chrome://gpuhang
chrome://ppapiflashcrash
chrome://ppapiflashhang
chrome://quit/
chrome://restart/
