In order to pick up any current probes, you must run the firefox-bin while you do these commands. Re-direct yourself to the Mozilla application you will use.

You are not to use dist/bin! If you do, it will run - but it will not retrieve keyboard input.

Upon running, it is wise to create yourself a seperate profile than the one you are using for Firefox. This helps if you have 2 different versions of it running at once.
