Well I'm sure profiles are a part of it. It got bad enough that I completely removed all profile and plugin data, and clean reinstalled. Firefox remains the worst performing browser I have on this system by very large measure. Five amazon tabs are enough to basically grind it to a halt. Chrome, IE, Opera and Palemoon (a fork of an older firefox) don't do that. So I've reached a point where I can't do much more to make it usable without a debugger. I've no doubt others are fine, or find Chrome the slow one. If everyone had the issues I currently have it'd be the single highest priority bugfix in the project. I'd maybe migrate to palemoon but I don't trust it on a security front.
