FWIW, I tried the dev edition (which is essentially Firefox beta) but I stopped using it as I kept running into bugs. A release that wasn't more buggy but allowed unsigned extensions would be nice.
I have been using exclusively dev and nightly for at least two years, and have only very occasionally run into issues. Of course, my usage is pretty typical web browsing, outside of using the dev tools.
It’s been long enough now that the normal colorful Firefox logo seems weird.
