I am currently running Fx Dev Edition 42.0a2 (2015-08-16). It updated today. In fact, it updates every day like I am on the nightly channel. I don’t want to develop my extensions with the “bleeding edge” Fx version - it’s too unstable. How can I change to the ‘beta’ channel and get updates only every six weeks or so?
I’ve already changed the pref app.update.channel from ‘aurora’ to ‘beta’ but it doesn’t seem to make a difference. In fact, it changes back to ‘aurora’ after every update.
What are my options if I want to install unsigned extensions in Firefox?
The Developer Edition and Nightly versions of Firefox will have a setting to disable signature enforcement. There will also be special unbranded versions of Release and Beta that will have this setting, so that add-on developers can work on their add-ons without having to sign every build.
These unbranded builds do not exist yet, but the will be very soon.
