This is a fork to show my personal changes.
Some may rely on my CSS changes, so they are meant to get inspiration to do something differently, not to be used as is (though it may work, with luck).
Below is the normal README.md from the ordinary project (some things are not relevant to my branch).
The Wiki contains a feature list (with screenshots).

\method 2\firefox\
folder copy defaults
folder and config.js
file to Firefox main directory (where the Firefox executable is; or on macOS, inside the main executable, at /Applications/Firefox.app/Contents/Resources/
). Edit
userChrome.js
file to add custom scripts.With Firefox 62+ and Thunderbird 68+ an additional preference
pref("general.config.sandbox_enabled", false);
has to be set inside config-prefs.js
file. This is considered less secure by Mozilla and is only a temporary workaround, but at the moment it is the only way to run custom scripts using "method 2".
