With bug 1275942 in Firefox 55, a new Firefox CLI option was added:
`--wait-for-jsdebugger`.
Example usage:
1. Add "debugger;" to top of browser/base/content/browser.js
2. $ ./mach run --jsdebugger --wait-for-jsdebugger
3. Browser Toolbox opens, pausing Firefox startup at the added line

As an occasional contributor to view source, I think it would be nice to
remove the MathML support from m-c like you are proposing, as it definitely
increased the maintenance burden when we reworked view source into a tab a

it increases risk because we are shipping untested code paths to our users
