disfunctional since FF13 Rated 2 out of 5 stars
The tricks to tame FF that are described here all became useless. When you leave FF all overrides are reset and I am not able to let Desktop be the default start, always about:home is imposed on me. A new release will need to sort this out.
Until then only two stars. The only work around is to have a link in bookmarks so you can quickly get to my desktop and not FF's replica of Chrome, which is utterly useless. I also report this to the FF dev. as a mayor annoyance.
Fixed in 1.4.7. You can update manually or wait a few days until it is reviewed and published.
