Location Bar: Changing results on the fly

Stolen from Mozilla.

If you are looking for a specific type of result, like a bookmark or tag, you can speed up the process of finding it by typing in special characters after each search term in the location bar separated by spaces:

  • Add ^ to search for matches in your browsing history.
  • Add * to search for matches in your bookmarks.
  • Add + to search for matches in pages you've tagged.
  • Add % to search for matches in your currently open tabs.
  • Add ~ to search for matches in pages you've typed.
  • Add # to search for matches in page titles.
  • Add @ to search for matches in web addresses (URLs).
  • Add $ to search for matches in suggestions.

Context Menu

Every once in a while, Mozilla decides to fuck with my setting, and an update changes it back. To enable Right-Click Context Menu on sites that don't want you to download that image you've been desiring all your life:

  • About:Config
  • contextmenu.enabled = false

Yes. False. !True. Just do it already!

Speed up Firefox

If you have a broadband connection (and most of us do), you can use pipelining to speed up your page loads. This allows Firefox to load multiple things on a page at once, instead of one at a time (by default, it's optimized for dialup connections). Here's how:

Type "about:config" into the address bar and hit return. Type "network.http" in the filter field, and change the following settings (double-click on them to change them):

  • Set network.http.pipelining to true
  • Set network.http.proxy.pipelining to true
  • Set network.http.pipelining.maxrequests to a number like 30. This will allow it to make 30 requests at once.
  • Also, right-click anywhere and select New→ Integer. Name it nglayout.initialpaint.delay and set its value to 0. This value is the amount of time the browser waits before it acts on information it receives.

Stolen From:

Tab Previews

Bring-up previews of all open tabs to select.

  • In your location bar, type about:config.
  • In the search, type ctrl.
  • Double-click browser.ctrlTab.previews.
  • Close the tab.

When you press Ctrl-Tab a preview of thumbnails will open as long as you hold the Ctrl key. While holding the Ctrl key, tap the Tab key to move between previews. Release the Ctrl key to go to the current highlighted preview.

Tab, Last Closes Window

Does closing the last tab close the window?

  • In about:config.
  • Type browser.tabs.closeWindowWithLastTab.
  • Double-click browser.tabs.closeWindowWithLastTab.
  • True allows window to close.

HTML5 Auto Play

  • About:config
  • media.autoplay.enabled
    • Double-click to toggle between true/false

Scroll Wheel Zoom

Profile Data Location

Most of your important items can be found in your user profile directory.

The files are located in:

The above directory can be found quickly by clicking:
Help > Troubleshooting Information > Profile Folder and clicking the Open Folder button.
Note: this changes slightly between versions, but is close enough you should be able to figure it out.

OR you can type about:support in the location bar.


To "export" saved logon information requires copying two files:

  • key3.db
  • logins.json
  • signons.sqlite

You have to manually hunt-down the above files, and copy to a safe place.

To "import" password/logon data, there's a nice, convenient button in your Tools → Options → Saved Logins" dialog.

user.js Preferences

Can you guess which file in your profile directory contains your user preferences?
