Mult accounts and since I upgrade to 15 fire fox. I can not use. my family We can not open accounts with : multifox 1.3.3 does not work the second person .

Question

hello,
I have 2 lab tops.. and have family members that use them.. I used to have FB open with mult family members accounts. Ad of today you updated to firefox 15..
Now when I go to use multifox 1.3.3 ( that is so you can have mult accounts open. ) .. if trying to go into Fb none of the features work. now since I have upgrade. it use to work fine.
So, the new FF does not work would like to unistall and go back to the old FF.. where I, can have mult accounts open at the same time and have the funcation work when your on the mult account in FB... Like talk to some one in FB chat. or just look at other items in the accounts.
if you can tell me how to fix this or can you please give me the old link back.. or tell me how to get the old link back instead of 15.. Because 15 does not work.
Thanks

Install or Reinstall OS X from Scratch
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Erase the hard drive:
  1. Select Disk Utility from the main menu and click on the Continue button.
  2. After DU loads select your startup volume (usually Macintosh HD) from the
      left side list. Click on the Erase tab in the DU main window.
  3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on
      the Security button and set the Zero Data option to one-pass. Click on
      the Erase button and wait until the process has completed.
  4. Quit DU and return to the main menu.
Reinstall OS X: Select Reinstall OS X and click on the Install button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible
           because it is three times faster than wireless.
