Sound Flower captures OS sounds, but not browser's audio

I was trying to capture audio of a webinar and Quicktime was capturing the OS audio as expected, but for whatever reason it was not picking up the audio from Firefox.  I decided that maybe it was a browser thing and I was right.  Logged in to the webinar with Safari and it worked perfectly.

Download Sound Flower before trying to record.

Download, install, and then open.  Once open, you will have a little icon at the top of the screen.  Select Sound Flower 2 Channel, Built In Output.

Open Quicktime

File -> New Screen Recording

On the upside down triangle, select Sound Flower 2 Channel

Start Recording!

How do I rotate my screen on an external monitor in OS X

1. Open the system preferences
2. Hold down the command and option keys while clicking the display icon
3. Next locate the screen adjustments on the external monitor and you will notice now there is an option called "Rotation".
4. Choose 90 Degrees and now your monitor is in portrait mode.

*A this can also be a funny prank on someone by doing this to their main monitor!
