- highlighting, links, themes*, re-size, wrap, about:config links/regex/groups
- expanding sections, and index to go to sections (with compatible user.js projects)
- compare preferences in two user.js, in a table format with order/layout options and bold cell border around differences
- actions including: user-overrides.js* append* (with comment-out*), point and click overrides collector, skeleton, prefs.js cleaner*, group by values
- load/save, drag/drop, or copy/paste user.js files (can load from some on-line URLs too)
- functions for find (filter/list)/reset/set on about:config Web Console (Firefox/forks/Thunderbird/SeaMonkey)
- single .html file (HTML/CSS/JavaScript) with no external dependency
- open userjs-tool.html on-line or save for off-line use
(*arkenfox/user.js inspired. Please visit arkenfox/user.js and read their info on arkenfox/user.js/wiki. They also have nice scripts for append/clean/troubleshoot.)
This started as an over the top experiment for learning some HTML/CSS/JavaScript (first released 2019.01.02, compare added 2020.02.22). This is a viewer/tool, and not an editor/installer.
