What I miss most in FireFox is better multiline script support in the dev console.
The current solution to copy the whole script into the console every time you run it is pretty cumbersome.
Also, when you opened the script from a file, ctrl+save should let you save it back with the same name. Not suggesting a name like "console-input-2022-11-13_9-36-47.js" every time.
