Like other stated. It used up too much space. Most of want it did can be done via Android or gestures if you have them.

Even the redesigned menu us a bit annoying since it takes one extra button press to get to extensions onto of an upward swipe.

As far as perhaps pitting it for you, try via the Secret Menu, of the mobile version of the Developer Mode.

It takes up space on the screen, which I know for some folks makes it a worthless/intrusive addition. IIRC it was also the case early on in the nightly builds that there was no way to turn it off either, which bothered people as well.

Everyone has "modes" they get used to using their apps with (and I am no exception in that regard, which is why I am here with this question in the first place), and when something new is added which disrupts someone's usual mode, that causes friction and a negative impression.

I know my experience is niche, being that I am a relatively newer Firefox mobile user who liked having that feature precisely because it more closely resembled the non-Firefox experience that was more familiar to me. So to an extent, I understand this decision that was made to avoid alienating the core user, even if that means potentially dissatisfying fringe users like myself. I also can't complain because this is the nightly build, where things change on a whim and there are no guarantees that any feature makes the cut (I would have been on stable build if this feature existed in the stable build at all).

Not to mention that Mozilla also isn't rolling in cash, especially with their future income model uncertain as the US government continues to go after Google's partner agreements that are currently propping Mozilla up, so they have to make difficult decisions about which features to spend time and resources supporting and which to cut.

But it still stinks, y'know?

Yeah coming from "normal" Firefox mobile it took me a minute to get used to it but this morning I immediately noticed it was gone and now I want it back :(

Which version are you on, out of curiosity? Wondering if you might be on an earlier version that hasn't updated yet or if they might be doing A/B testing or something.
