I heart the fox

I am very satisfied with all the settings and extensions I have on my Firefox. Is there anyway to back up my settings and extensions in case I'll need them after my computer needs to be formatted?

I love Firefox...I tried to move my Firefox settings to my new PC in my sig, but it didnt work. I installed Firefox on the new PC...the copied and pasted the Firefox folder from the old PC to the new one but it didnt work...must be hidden in the registry I guess
