I highly value my privacy; I switched to iOS because of it. I only use Chrome at work. I've got comprehensive content blockers set up on mobile Safari, which is where most of my personal browsing happens.

I'd assume that's a version designed for developers who work on Firefox itself, not developers who use Firefox to work on the web. There would be no reason for them to omit some of their dev tools from the regular builds.

I tried and loved Vivaldi for a little while, until I ran into a catastrophic dev tools bug (can't remember what exactly). I also enjoyed Brave for a while, but it ended up being too slow too (this was when it had an Electron interface instead of being a fork, so it's probably better now).
That is a an incorrect assumption:

And why would there be no reason to omit these tools? If they're only going to see the light of day when a developer is using them, they're a waste of space for the average user, correct?
I don't know how it is for other people, but the way Firefox's scroll works on mobile makes me want to not do anything on it. If Firefox were my only option to browse the internet on my phone then I just wouldn't.
One thing you could try to see if Firefox speeds up by changing the number of processes it creates (defaults to 4) to 8, esp if you're on a machine with considerable RAM (16GiB+).
As for web-dev tools, doesn't Firefox ship a developer-only edition? Might want to try that out.
