Extension summary

Analyze keywords

This extension allows you to inject any javascript code into the web page you are visiting. It remembers your page specific script and syncs it across all your devices.

For example, if you want to change the background color of https://duckduckgo.com/ with light blue, you can inject the script 'document.body.style.backgroundColor = "lightblue";' using this extension. After that every time you open this web site, the back ground will be light blue automatically.

Okay tool I would say, but it would have been nice if the GUI was reworked a bit, and if it actually supported the `window.addEventListener(func)`. For me this never triggers, and I have to sometimes run the code at a point that it only affects part of the page because other elements have not fully charged yet.
