open firefox
click tools>add ons
drag the all-in-one file or individual extensions into the add ons window
wait for instal to complete and restart
note: if you already have some of these extensions they will update

the images folder is for the fission progress bar and a few custom favicons

enjoy!

note: if you install them all at once, you will be slightly overwelmed by configuration windows. no worries though, you only have to do them once.
