I've haven't used it before just now but the Android version of Firefox has an extension called "MobiDevTools" on their extension store. It has various web developer tools, including a developer console. For some reason it doesn't seem to open when I'm on the extension store but it works just fine with every other website I tried.

it doesn't seem to open when I'm on the extension store
Firefox marks certain pages as privileged and no extensions will run on them. You're probably encountering this issue. You can see the full list here.
Someone mentioned this in the cross-post. It seems the best alternative so far but I think it doesn't let you edit the html, only remove elements, and the network tab doesn't really work because the extension closes on refresh. The console should work fine though
if the console works fine, you should be able to use javascript to edit/manipulate the html. just need to learn a bit of js and css selectors.
Huh true, and since you get to see ids and class names in inspect it's not too bad.
For some reason it doesn't seem to open when I'm on the extension store but it works just fine with every other website I tried.
all addons are prohibited to run on a few protected domains like the adfons store. this is an old security measure, desktop has it too
I just use some browser called Element Inspector from Play Store, but it was last updated in 2023, and is closed source.
The about app points to: https://linkbox.su/r/mixno35 which either returns 500 or 504 errors.
Alternatively, you could try desktop Firefox under Termux, but that is probably not the most elegant solution. But it's a good solution for large background uploads it seems.
Getting another dead browser doesn't make too much sense tbh, might as well keep kiwi. I hadn't thought of the desktop thing, I could try it at some point.
i have a debian os running in termux.
I sometimes use it to debug websites on my phone running desktop version of firefox via vic
You don't even need to fuck around with Debian chroot/proot. Termux also has an X11 repo. I run XFCE in it, works well. There's less programs available though, but Firefox is there.
I think the Kiwi browser has it. EDIT: Or had it when it existed. I don't see it on Google Play anymore.
What exactly do you need it for?
It's possible to debug mobile Chrome by connecting your phone to a desktop. You can even debug some apps that way.
I know remote debugging is a thing but it requires a computer. Sometimes you want to check something on the go. Alternatively, changing some html on the page when something displays weirdly on a phone (or removing pop-ups but ublock takes care of that too).
