You know the problem: tons of add-ons are bloating your Firefox. Including slower rendering speed and start-up. This is especially true if you are a web developer because there are many useful but heavy extensions you never need if you are not working on a project. Different profiles and starters/shortcuts may help you out. It works for me1) and I'm sharing my approach here (maybe it is useful for someone else).

I really love my Firefox again. You don't need to switch to Chrome/Opera to get a fast browser.
