compare-user.js

A python application to compare multiple user.js files.

The user.js of Firefox allows to configure your browser to your needs. There are different examples out there, but to manually compare them with each other takes time. This python application allows to print out a summary about the differences of two user.js files as input.

Additionally it allows to print the differences in the format of the user.js files when used with the parameter -printLines

Requirements

Install dependencies with pip:

pip install dictdiffer tabulate

Or install with

pip install -r requirements.txt

Usage

Just compare two files and get difference summary (added values, removed values, changed values):

python3 compare.js user.js user.custom.js

Same as above, but also prints out the values in user.js format, so they can be easily integrated into your files.

python3 compare.js user.js user.custom.js -printLines

Sources for user.js files

There are projects like Arkenfox/user.js or pyllyukko/user.js which provide customized user.js files.
