If you hate navigating folder locations to save your files then get this Rated 5 out of 5 stars
This add-on is an extremely handy timesaver. Navigating folder locations to save your files is one of the most mundane, repetitive, and annoying tasks in a computer user's world. Anything to make this process simpler is a winner in my book. And this add-on definitely does that.
It'd be nice though if there was a way to import/export your settings so you don't have to set up all your folders again if you have to reinstall firefox.
