«The Nightly and Developer Editions of Firefox based on 42 and above will retain the preference to disable signing enforcement, allowing the development and/or use of unsigned add-ons in those versions»
So I think running the Developer Edition (which I expect to be much more stable than Nightly) is probably your best bet.
The thing is, I'm not a web developer and I don't think I should be forced to use the Developer Edition just so I can remain in charge of what I install in my browser. Now that I'm writing this it occurs to me that after this change it's not really my browser anymore, is it?
I hear you on the control thing. You mention you are a power user above so my two cents is that likely puts you outside of the user base Mozilla covets. In the last couple years, the words "Firefox" and "power user" went hand-and-hand but I'd wager Mozilla would trade customer bases with Google in a heartbeat.
FWIW, the Developer Edition feels pretty lean and mean. I haven't tried since I am a web developer, but it looks like you can remove most or all of the parts that make it web developer-y if you are so inclined.

Mozilla's business model needs users who can't figure out how to turn off Yahoo search. That pays for their new Firefox offices on the waterfront in San Francisco.[1]
I've ran Nightly and Aurora (which is now Developer Edition) for a while but extensions/themes broke more often than I'd have liked because there was too little time for extension devs to update their extensions in case incompatible changes were introduced.
I don't know if they'll offer each permutation of all those possibilities. I don't see why not though, it's just a little more build time.
In any case, if the specific combination of features you want is missing, the option to build from source is always there. (At least on Linux, building Firefox is also pretty easy.)
That doesn't sound like an option that will fork for my use-case - I manage a bunch of Windows machines; if we upgrade Firefox to "Noname Browser" with a different icon, the users will be confused and unable to find it.
i tried running firefox developer for a while and since it's based on the alpha code, it broke all my extensions on each update. so yeah, i'm a power user (i run 3 custom extensions that i wrote, pentadactyl and dotjs) but it's not feasible for me to keep running developer.
Agree. And as someone who's been running the Developer Edition as his primary browser for some time, I'm happy to report that it has been by enlarge reasonably stable--even though I've had e10s enabled.
This was true for me until the most recent major version (42.x) that broke the Tree Style Tabs extension. My whole browsing workflow depends heavily on that extension, so I had to revert to using the stable version for now.
https://github.com/piroor/treestyletab master works fine; you just have to clone it and replace extensions/treestyletab@piro.sakura.ne.jp in your profile.
I also used to rely pretty heavily on Tree Style Tabs. With the release of 42 I've been using tab groups (cmd+shift+e) with pretty satisfactory results.
e: cmd+shift+e assumes a Mac. Not sure what other systems use.
Hmm, i'll have to try that thanks for the heads up.
Losing tree style tabs in 42 has made me nervous, it was the primary reason I love firefox. Without that most of the why in using firefox goes away for me.
As I understand, the author's opinion is that Adobe Reader is more secure than pdf.js. I'm not sure I would trust them with maintaining a secure browser in light of that.
Their monetization model is also questionable (I understand it injects ads / referral links).
Never heard of it, quick scan of the page seems to indicate that it is windows/linux only though? I did a quick look at the download page and didn't see an osx build.
That is overall fine but I like to keep my browsers portable across all of my primary operating systems.
The Developer Edition won't help much if plugins that don't fit the new API are abandoned, which strikes me as a likely occurrence. I don't think many will bother to maintain non-developer-oriented plugins just for those using the Developer Edition.
So I think running the Developer Edition (which I expect to be much more stable than Nightly) is probably your best bet.
