FF3 - Firebug Question

[SooTyLaD]

Just started using firebug and i have read time and time again that it can edit live sites, so with my sites that are online i should be able to make live amendments yeah?

the reason i ask is i can't for the life of me work out how to change live stuff on the fly (obviously there needs to be some sort of ftp login credentials entered somewhere?)

could anyone give me a leg up?

so the workflow with firebug is use it to sample changes, then make em for real at a later time?

i can sort of see that being useful with some things like if your messing with some unfamiliar code but on your own sites where you pretty much know where everything is and what it does thats just doing the work twice...

am i missing something?
