Comparison table of all builtin Keyboard and Mouse shortcuts as used in Firefox, Google Chrome, Internet Explorer (IE8), Opera, and Safari as used in Windows.  Learning keyboard shortcuts is essential to getting the most out of your browser, whether you are or are not a power user. 

While this is mainly oriented to help relate Firefox shortcuts to or from other browswer, it is also probably the most complete list of shortcuts for each browser (only oriented to browser shortcuts).

Keyboard and Mouse Shortcuts

The Mac Cmd key ( ⌘ ) is generally same as the Windows Ctrl key.  Windows Alt key could be either Mac Cmd or Mac Opt key.
The Unix 'accel' key is usually same as Windows Ctrl key but could be set to Alt.
Windows wording Tools → Options would be Edit → preferences on Linux, or Firefox menu → preferences on a Mac.

There are rows in the above table, including (approx) 15 color coded heading rows, 13 sub-topic or empty spacer rows, and 13 (grayed) rows without a comparable Firefox keyboard shortcut. 

  1. The area with red text under Mouse Shortcuts can be reversed to match other Browsers, select Tools → Options → Tabs → [x] When I open a link in a new tab, switch to it immediately.  This is the same setting that can be changed by setting browser.tabs.loadInBackground to False to set focus on new tabs opened from links (load in foreground)
    So that bookmarks open the same way as links, these about:config settings should be *same* as each other:
    - browser.tabs.loadBookmarksInBackground (default is False), controls focus of bookmarks opened in new tab
    - browser.tabs.loadInBackground (default is True), controls focus of links opened in new tab
  2. The area with brown text mostly pertaining to Home, End, PgUp, PgDn pertains to or is especially useful on small laptops where use of the Function (Fn) key is required on small sized keyboards, the Fn choice may not always be the best though if another choice is available, especially if you are holding the small laptop in one hand.  Firefox is the only browser I use on my small laptop.
  3. Suggest not setting Middle-click to any Firefox or other browser specific behavior.  Best if middle-click is set in your system to Enter.  Works well from dialogs, and from entry areas such as search bar and Location (/address) Bar.  (Click on "Enter test").  See mouse.
  4. See all Firefox and user added Keyboard shortcuts with the "keyconfig" extension ("Ctrl+Shift+F12") and to resolve conflicts, such as new in Fx3.1 Private Browsing (Ctrl+Shift+P grabbed Adblock Plus preferences which in turn now uses Ctrl+Shift+F).
  5. The above table should be a complete list (close to 150) of built-in Firefox keyboard and mouse shortcuts, and about as many for each of the other browsers as well.  [keyconfig documentation]

Mouse shortcuts: Highlighting a word or sentences (double-click, triple-click) varies quite a bit depending on extension and possibly options.

Ctrl+L selects content of location bar, then use of arrow keys or End key, or Ctrl+arrowkey will navigate within where you are at (in this case Location Bar).  Double click selects word, triple-click (may) select sentence/paragraph/line.  Try the same elsewhere: Search Bar (Ctrl+K), text areas, main body of web page.

For another day, find which browser and what options for showcase tab, show thumbnail of window, on link or tab, and how to remove it. Fx 3.6 drops tab dropdown list for horrid showcase as in some other browsers. One of the Firecase options is nglayout.enable_drag_images for image of a link.

Firefox configuration variables relating to clicking on a link or on a bookmark. (#newtab)
Name Type Meaning of Values (extracted from MozillaZine KB, also see Tabs configuration)
browser. search. openintab Boolean True:  When performing a search from the Search Bar, open the results in a new tab.
False (default):  Open search results in the current tab/window.
Note:  Firefox nightly trunk builds only.
If you foolishly installed Tab Mix Plus then controlled by
browser. tabs. loadBookmarksInBackground Boolean Focus behavior of new tabs from bookmarks & history
True: When you open a bookmark in a new tab then that tab will load in the background without taking focus from the current tab.
False (default): When you open a bookmark in a new tab then that tab will become the current tab.
Note: you likely want to set this to the same setting value as used for browser.tabs.loadInBackground [Bug 469456]
Note: Firefox 1.0.x had a Tabs option for "Select New Tabs from Bookmarks or History"
browser. tabs. loadDivertedInBackground Boolean Determines behavior of pages normally meant to open in a new window (target="_new") or from an external program), but that have instead been loaded in a new tab.
True: Load the new tab in the background, leaving focus on the current tab
False (default): Load the new tab in the foreground, taking the focus from the current tab.
Note: Setting this preference to True will still bring the browser to the front when opening links from outside the browser.
Note: target="_new" creates/reuses a window named "_new" and is frequently used by Google.   target="_blank" loads the designated document in a new, unnamed window [ [1]].
browser. tabs. loadFolderAndReplace Boolean True (default):  When opening a folder of bookmarks in tabs, the existing tabs will be replaced by the new bookmark pages.
False:  Existing tabs will be preserved when loading a folder of bookmarks. The bookmark pages will be loaded in tabs that are appended to the current tabs.
Even with the setting at True, if you don't want to lose the current tab, and want new tabs at end instead of adjacent to active tab use Ctrl+Shift+click on "Open all in Tabs" (or Ctrl+click ..., whichever shortcut will load new tab(s) in foreground is the only one that will work)
Bug 175124 - improve open in tabs behaviour,
browser. tabs. loadInBackground Boolean Focus behavior for new tabs from links
True (default): Do not focus new tabs opened from links (load in background)
False: Opposite of above
Note: bookmarks & history can be opened similarly in browser.tabs.loadBookmarksInBackground [Bug 469456]
Note: In Firefox, this can be changed via "Tools → OptionsTabs → When I open a link in a new tab, switch to it immediately (Firefox 2 and above)

Google Search results > upper right corner gear/settings:
Results Window: [x] Open search results in a new browser window.
Google no longer uses Target="_new", so this option does what it should, either opens in same window/tab, or opens in a new window/tab (not a reused window named "_new")   Boolean   True -- When performing a search from the Search Bar, open the results in a new tab.

Special Characters (#special)

Windows Desktop: use Alt+(4 digits) from numeric pad to get special characters.
Windows Laptop: use Fn+Alt+(4 digits) from numeric pad to get special characters.

Missing Toolbars   (#toolbars)

Help Files -- Keyboard Shortcuts (#help)

Additional Browser Comparisons (#compare)

Firefox Extensions (#ext)

Extensions may add keyboard shortcuts, menu items, particularly context menus, tools menu, or other means, but the keyboard shortcuts can save you a lot of time, if you learn to use them.

Firefox Extensions can add quite a number of keyboard shortcuts, two listings were grabbed on 2008-07-12 in Firefox 3.0 both were created with the "keyconfig" extension and placed into text files with help from SnagIt® Software.  The list without extensions can be compared to the same listing with extensions (these are both text listings).

The Launchy extension can be used to look at the page you are viewing in Firefox on a Windows system with another browser or other applications from context menu, tools menu or from a Toolbar button.  I prefer the toolbar button if it's the page I want to see elsewhere, but for objects within the page you would have to access Launchy through the context menu.

The PageDiff extension can be used to compare the two text (source) listings of two different webpages.   Another useful comparison tool is Quick Diff Online Tool, an Online Tool to do a 'quick and dirty' diff of two text or code fragments -- or you can paste in the visible text from web pages for a comparison (runs from a webpage not browser dependent).

You can use the Split Browser extension to place an alphabetical by shortcut listing (without extensions) to the right hand side of this listing, so you can see two different views.

TableTools allows you to sort a table such as on this page by any column, and to filter the table.  Table2Clipboard allows one to select and copy rows, columns or the entire table to paste into Excel, OpenOffice, or CSV for plain text.

The extensions I use are listed on my home page, and you can get an idea of which are probably in use from my InfoLister Listing.

Restore missing underscored letters in menus (turned off by default in Windows 7) (item #9 approximately)

Extensions to avoid or use caution with based on stepping on Firefox, Windows, and other extension's keyboard shortcuts:  "MenuX", "Next Please", "Site Launcher", "Tab Utilities", and "Web Developer".

To resolve occasional conflicts there is the "keyconfig" extension (23KB download) available at the author's site.[notes]
