Rated 5 out of 5 stars
This multisidebar addon has been updated for ff3.6* here:
It was updated by ChoGGi who is an author of another firefox addon called Stylish-Custom here: https://addons.mozilla.org/en-US/firefox/addon/12105/
So it is a VERY SAFE and TRUSTED download. A very quick and easy download with no complications or other steps to do. I am using it and it is PERFECT. Thankyou SO MUCH ChoGGi !!!!!!!!!!
