I have Firefox Preview Nightly, and Firefox for Android Beta, and Firefox for Android all on my Android. And I like the fact they are (were) three separate apps. And I want to keep them that way (until/unless you make rather large changes that might allow an all-in-one, per A-D below). Preview Nightly, I use for Facebook, because I definitely don't want to install a Facebook app on my phone. If you had containers for Firefox for Android, I wouldn't need Preview Nightly, but you don't. Firefox for Android Beta, I use for sites that are particularly pernicious, so much so that uBlock Origin is not enough and I use noscript as well. Noscript cannot be installed on regular Firefox for Android (at least it couldn't in the past) or Preview Nightly (definitely can't). Firefox for Android, I use for everything else. It is a bit slower than Preview Nightly, but it basically has all the kinks worked out. Also for most Android sessions, I don't need noscript (it's harder to install malware on a non-rooted phone than it is a PC, and noscript's a bit clunkier on Android) so it's nice to have a default Firefox without it that I can get to in one tap. Also, unlike Preview, Firefox for Android interacts with LastPass. To get rid of all three and just use one, I would need A LOT in a single firefox browser: A) Containers. I refuse to install a Facebook app and I hate having to open a private window and relogging in constantly. There are other sites I would want this for. B) Noscript. It doesn't have to be that add-on, it could be an add-on/functionality like it. But a simple toggle on-off of javascript in settings just doesn't cut it (how much can one really do with javascript completely off?). I need to be able to turn on/off javascript by hosted site. I need to turn on just the script urls I need for a page and leave off the really nasty ad/tracking script urls. However, this is only on occasion, maybe one browsing session a day and/or specific to sites. Turning on and off script urls is tedious in mobile, so I would need "C" (below) too. C) Widgets. Widgets that I can place on my Android home screens to start Firefox with different functionality. Ideally they would start in a specified container and with specified add-ons/functionality activated or deactivated. Example: Widget 1 opens Firefox with noscript-functionality globally off (is default for opening links). Widget 2 opens Firefox in Facebook container and has Facebook as homepage. Widget 3 opens Firefox in a safe container that has noscript-functionality globally on (javascript blocked) except a few sites already set as okay to run javascript. D) LastPass (field fill). LastPass developers say they won't develop for Preview (already asked). If you create some kind of Firefox Lockwise portal that connects to my LastPass, that allows temporary transfer of credentials so I can fill Firefox mobile web pages, that would suffice. But I am not abandoning LastPass, and I do not want to store all my passwords permanently/duplicated into Lockwise. However, others probably need field fill so a better solution might be some way to temporarily make the browser look like its chrome based (because that's apparently what LastPass needs) just long enough to get the fields filled in, then revert back. This could be something toggled from a menu, that's fine. It would still be vastly easier than constantly switching between apps and copying and pasting. If there is A, B, C, and D--then I wouldn't need three different apps. Until/unless you develop that, please leave Firefox Beta off of the Preview build. Keep it separate. I think you are trying to force people to eventually go to Preview, much like you forced everyone to adopt the Chrome-build version of Firefox for Desktop. That was a painful transition, but at least add-on developers could look to existing Chrome add-ons to know how to transition. Firefox is going to something unlike a major competitor, so the add-on developers will be completely unprepared, and it might kill add-on development. And if add-on development goes, and LastPass still can't interact, then there's very little need for firefox over chrome for me, regardless of speed improvements and anti-tracking. I'd probably just keep Firefox to run Facebook and that's it. I doubt I'm the only one with similar needs. That is, I need something particular from each of these slightly different apps (or at least they were all different until Firefox Beta became Preview) and I need all three until there's a solution that would let me use only one. But my solution may not be everyone else's, so you might want to keep all three apps going as separate in the meantime. While you have three, keep developing in Preview Nightly my all-in-one solution (containers, noscript-like features, widgets to turn open different profiles, lastpass / field fill functionality) and anyone else's all-in-one needs (ask people what they'd need from Firefox or Firefox Beta that they can't get in Preview). Once that's achieved, then maybe you can merge the products into a single one you can maintain alone.
