Yeah, but it's a massive reworking of the FF internals, so it took a long time to complete. But I'm using it now, and it works pretty well.
My only hitch was needing to turn off some older add-ons. While Mozilla is still doing a slow roll-out, it disables E10s if it can't ensure your plugins will work. (One of mine was a HN add-on, amusingly.)

Most of the opoular add-ons are ready, though. To check, see: https://www.arewee10syet.com/
