Is there ANY WAY to run a javascript on parent process like how we run CSS on userChrome.css?
Hello,
I created a loading progress bar for Firefox which uses JavaScript to show how much of the current page is loaded at the bottom of the address bar.
Is there any way I can automate running JavaScript at the opening of a window? Like how we can change the appearance in userChrome.css?
Currently I'm copy pasting the script to console at the start of every window.

Yes, it is possible to inject privileged script code into Firefox at startup, but I really have no idea how you would run that particular code.
As a starting point, check out my article: https://www.userchrome.org/what-is-userchrome-js.html
