Styler

A great extension. Enabling Javascript and having a built in jquery library, makes tweaking sites easy. I use it to add classes to elements, remove panels from pages, resize sections like a canvas with css, debounce searches on inputs, add my own buttons to pages for ease of use and scrape data by querying the dom and use the mutationobserver to watch for changes and act on them. This extension is like a macro tool that allows me to customize some sites I use to enter or retrieve information... Show more

I was looking to inject custom css and js in certain pages to battle against the new distractions (games tab, marketplace) that facebook (and other sites) comes up with. I was looking at Greasemonkey and found it too complicated for my needs. This one really fit the bill

Used to be good, now the JS part doesn't work anymore.
