SMUUI (Stack Machine Unified User Interface) or simply FireFORTH (any legal implication?) -- extension for Firefox

Just to update about my plan now:

(1) managed to compile Firefox from source. It was much easier than I thought.

The correct way is given here:

https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Build_Instructions/Simple_Firefox_build/Linux_and_MacOS_build_preparation

(2) Now I will start work on SMUUI (Stack Machine Unified User Interface) or simply FireFORTH (any legal implication?)

Summary: The Stack Machine Unified User Interface (SMUUI) is an extension of the ubiquitous Unix terminal and the Browser Console, with Reverse Polish Notation commands and facilities, to interface to high level functions in high level programming languages, as well as low level Forth-type assembly instructions. It is essential in the era of Cryptocurrency Browser Mining, as even novice users would like to be sure they can control and monitor the computer or mobile device down to a single clock cycle.

BCPL, grandfather of C, has a stack machine architecture. Bourne, worked with Burroughs Algol before joining the Unix team, gave rise to the ubiquitous Bourne shell. dc, was a stack machine. SMUUI is a return to the original path.

There was a need for Unix to be portable to non-stack machine architecture, as manufacturer of microprocessors and computers then would produce register machines as well as stack machines.

Just to report my progress if anyone is interested to collaborate:

1) I have joined Firefox DevTools Slack group #general and #console.

I posted a brief introduction about SMUUI. Just waiting for replies.

2) Here's backtrace from gdb of Firefox -- running alert("hi") from Console, then Ctrl-C back to gdb. It might give us an idea the code structure and decide which file to change to put in a Forth(-ish) shell:

Here's another backtrace in Firefox. It looks as if JavaScript jit is also a stack machine:

Here's a good point to start. annotate-page is an example where user text input can be accepted into Firefox, the first step to make a Forth-ish shell:

https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/Examples

annotate-page Displays a sidebar that lets you take notes on web pages.
