All keyboard shortcuts - Firefox Developer Tools

This page lists all keyboard shortcuts used by the developer tools built into Firefox.

The first section lists the shortcut for opening each tool and the second section lists shortcuts that are applicable to the Toolbox itself. After that there's one section for each tool, which lists the shortcuts that you can use within that tool.

Because access keys are locale-dependent, they're not documented in this page.

These shortcuts work in the main browser window to open the specified tool. For tools that are hosted in the Toolbox, they work to close the tool if it is active. For tools like the Browser Console that open in a new window, you have to close the window to close the tool.

1. Unlike the other toolbox-hosted tools, this shortcut does not also close the Web Console. Instead, it focuses on the Web Console's command line. To close the Web Console, use the global toolbox shortcut of Ctrl + Shift + I (Cmd + Opt + I on a Mac).

2. Before Firefox 55, the keyboard shortcut was Ctrl + Shift + Q (Cmd + Opt + Q on a Mac).

3. Until Firefox 38, when the Browser Console is hidden by a normal Firefox window, the same key combination closes the Browser Console. From Firefox 38 onwards, if the Browser Console is hidden by a normal Firefox window, this key combination brings the Browser Console back on top and focuses on it.

4. The tool is disabled by default, so the shortcut would not work until it is enabled from the Settings Panel

Source editor

This table lists the default shortcuts for the source editor.

In the Editor Preferences section of the developer tools settings, you can choose to use Vim, Emacs, or Sublime Text key bindings instead.

To select these, visit about:config, select the setting devtools.editor.keymap, and assign "vim" or "emacs", or "sublime" to that setting. If you do this, the selected bindings will be used for all the developer tools that use the source editor. You need to reopen the editor for the change to take effect.

From Firefox 33 onwards, the key binding preference is exposed in the Editor Preferences section of the developer tools settings, and you can set it there instead of about:config.

Page Inspector

Node picker

These shortcuts work while the node picker is active.

HTML pane

These shortcuts work while you're in the Inspector's HTML pane.

Breadcrumbs bar

These shortcuts work when the breadcrumbs bar is focused.

CSS pane

These shortcuts work when you're in the Inspector's CSS pane.

Debugger

Debugger (Before Firefox 52)

1. By default, on some Macs, the function key is remapped to use a special feature: for example, to change the screen brightness or the volume. See this guide to using these keys as standard function keys. To use a remapped key as a standard function key, hold the Function key down as well (so to open the Profiler, use Shift + Function + F5).

Web Console

Command line interpreter

These shortcuts apply when you're in the command line interpreter.

These shortcuts apply while the autocomplete popup is open:

Style Editor

Scratchpad

Eyedropper

Web Console Helpers - Firefox Developer Tools

The commands

The JavaScript command line provided by the Web Console offers a few built-in helper functions that make certain tasks easier.

Switch JavaScript evaluation context to a different iframe in the page. This helper accepts multiple different ways of identifying the frame to switch to. You can supply any of the following:

• a selector string that will be passed to document.querySelector to locate the iframe element
• the iframe element itself
• the content window inside the iframe

See working with iframes.

Please refer to the Console API for more information about logging from content.

Variables

Examples

Looking at the contents of a DOM node

Let's say you have a DOM node with the ID "title". In fact, this page you're reading right now has one, so you can open up the Web Console and try this right now.

Let's take a look at the contents of that node by using the $() and inspect() functions:

This automatically opens up the object inspector, showing you the contents of the DOM node that matches the CSS selector "#title", which is of course the element with ID "title".

Dumping the contents of a DOM node

That's well and good if you happen to be sitting at the browser exhibiting some problem, but let's say you're debugging remotely for a user, and need a look at the contents of a node. You can have your user open up the Web Console and dump the contents of the node into the log, then copy and paste it into an email to you, using the pprint() function:

This spews out the contents of the node so you can take a look. Of course, this may be more useful with other objects than a DOM node, but you get the idea.

Command Line Options - Mozilla

Command line options are used to specify various startup options for Mozilla applications. For example, you can use command line configuration options to bypass the Profile Manager and open a specific profile (if you have multiple profiles). You can also control how Mozilla applications open, which components open initially, and what the components do when they open. This page describes the commonly used options and how to use them. You can open the Command Line Interface by pressing Shift + F2.

Syntax Rules

But first, let's describe the syntax rules that apply for all options.

• Command parameters containing spaces must be enclosed in quotes; for example, "Joel User".
• Command actions are not case sensitive.
• Command parameters except profile names are not case sensitive.
• Blank spaces ( ) separate commands and parameters.
• Each message option follows the syntax field=value, for example:
  • [email protected]
  • subject=cool page
  • attachment=www.mozilla.org
  • attachment='file:///c:/test.txt'
  • body=check this page or also in Thunderbird 52 and newer: body=c:\path\to\file.txt
• Multiple message options are separated by comma (,), for example: "[email protected],subject=cool page" . Comma separators must not follow or precede spaces ( ). To assign multiple values to a field, enclose the values in single quotes ('), for example: "to='[email protected],[email protected]',subject=cool page" .

Using command line options

Command line options are entered after the command to start the application. Some options have arguments. These are entered after the command line option. Some options have abbreviations. For example, the command line option "-editor" can be abbreviated as "-edit". (Where abbreviations are available, they are described in the text below.) In some cases option arguments must be enclosed in quotation marks. (This is noted in the option descriptions below.) Multiple command line options can be specified. In general, the syntax is as follows:

Examples

The following examples show the use of the "-ProfileManager" command, which will open the Profile Manager prior to starting Firefox or Thunderbird:

Windows

Select Run from Windows Start menu. Type:

Mac OS X

Go to Applications > Utilities. Open Terminal and type:

If you use Firefox Nightly, you can type:

Linux

Open Terminal and type:

The example above invokes the "-ProfileManager" command line option with Mozilla's Thunderbird mail client.

User Profile

-CreateProfile profile_name

Create a new profile in the default directory, but do not start application. The profile will be named profile_name in the profile manager. profile_name must not contain spaces ( ). To use this successfully no instance of the application must be running, or the -no-remote options must be used.

-CreateProfile "profile_name profile_dir"

Creates a new profile in the profile_dir directory, but do not start application. The profile will be named profile_name in the profile manager. Note profile_name and profile_dir are quoted together, and are separated by exactly 1 space (as with the previous syntax, profile_name must not contain spaces).

To use this successfully no instance of the application must be running, or the -no-remote options must be used.

NOTE: profile_dir must not exist and you must not already have a profile called profile_name.

-migration

Start with Import Wizard.

-new-instance

Open new instance, not a new window in running instance, which allows multiple copies of application to be open at a time.

-no-remote

Do not accept or send remote commands; implies -new-instance.

-override /path/to/override.ini

Load the specified override.ini file to override application.ini (browser/app/application.ini). This can be used to suppress the Migration Wizard at startup by loading the following override.ini. Firefox only.

-ProfileManager

Start with Profile Manager. Short form: -P without a profile name.

-P "profile_name"

Bypass Profile Manager and launch application with the profile named profile_name. Useful for dealing with multiple profiles. Note profile_name is case sensitive. If you don't specify a profile name then the profile manager is opened instead. You must use an upper case P on Linux with versions older than 7.x, as there lower case invokes Purify mode (memory and leak detection). Other platforms accept both upper and lower case.

-profile "profile_path"

Start with the profile with the given path. Firefox, Thunderbird and SeaMonkey2.x only.

"profile_path" can either be an absolute path ("/path/to/profile") or a relative path ("path/to/profile").

Browser

-browser

Start with the browser component. Firefox and SeaMonkey only.

-foreground

Make this instance the active application.

-private-window URL

Open URL in a new private browsing window. If a private browsing window is already open, a new tab is opened in the existing window. Firefox 29 and later only. Does not work in Firefox 31 on linux mint 17 nor on Firefox 48 on Windows 7. URL opens in a non-private window.

-search term

Search term with your default search engine. Firefox and SeaMonkey 2.1 and later only.

-setDefaultBrowser

Set the application as the default browser. Firefox only.

-url URL

Open URL in a new tab or window, depend on the browser option. -url can be omitted. You may list multiple URLs, separated by spaces. Firefox and SeaMonkey only.

Note: When opening multiple URLs, Firefox always opens them as tabs in a new window.

-purgecaches

Gecko (layout engine) has a javascript cache, which is not reset on startup. This clears it.

-start-debugger-server port

Firefox only. Start the debugger server on port. This will enable another instance of Firefox to connect the Firefox Developer Tools to this Firefox instance. See the article on remotely debugging Firefox Desktop.

The port argument is optional, and if it is omitted, the server will listen on port 6000.
