How can I force Firefox to quit on a Mac? Real-time problem.

I've got Firefox running on a Macbook Air and it's hung, with the little color wheel spinning. How can I stop Firefox only, without a forced shutdown? (On Windows I'd use Ctrl-Alt-Delete and end the process.) Note that I need a keyboard solution -- I can't use my mouse in Firefox in this situation.

Best answer: Option-Command-Escape.
Smash em all at once.

Click on the apple upper-left. Force quit is in the pull down menu.

Oh, shoot, now I notice the keyboard restraint.

Option-Shift-Command-Esc (hold for three seconds)- to force quit the front-most application.

If firefox isn't fullscreen you can also try clicking outside firefox to get back into the finder, that should let you access the apple menu/force quit.

Sometimes that doesn't even work. Firefox is the worst, on OSX, when it beachballs.

Also, option-click on the icon in the dock. This lets you easily choose which application to force-quit.

Just for the sake of having another way: You can also use the terminal to kill any process. Here's me killing firefox. First, I find the PID (first number on the line) using ps and grep. Then, I kill that process with the 'kill' command. (notice that grep is also going to find itself, so you'll get two lines of output from that part.)

dexter:~ ctmf$ ps -ax | grep firefox
3059 ?? 96:15.39 /Applications/Firefox.app/Contents/MacOS/firefox -psn_0_1696158
9536 ttys000 0:00.00 grep firefox

dexter:~ ctmf$ kill 3059
dexter:~ ctmf$

More complicated, maybe. But I can't remember all these dumb key combinations for every-damn-thing on the mac, so I just use my unix tools when I know how.

Here are a couple of other ways:

- Click on the Apple menu (apple icon in the top left of the menu bar) and choose "Force Quit"

- Open Spotlight (mouse method is to click the magnifying glass icon at the top right, keyboard method is command+spacebar), then type "activity monitor". The activity monitor is very similar to what you get with ctrl+alt+delete in Windows, so it should be pretty easy to figure out what to do.
