Why not switch to Firefox Beta to get those improvements immediately? With the removal of the aurora channel, Mozilla is trying to get more people on the beta train, that now is the only stabilization phase between Nightly and Release.
As a die-hard Nightly user I usually install the Beta (x64) version for other users and, depending on the add-on compatibility, enable e10s or some other features (e.g. TCP Fast Open) that may already be in A/B testing. Right now it makes an amazing difference in user satisfaction.
yes, i have developer edition installed for testing, but still use the release version as my main browser. it's just a couple weeks left to wait so i think i can hang on until then. =)
