Run Javascript Extension
Run custom Javascript, each time you visit a website.
This extension is particularly useful to web developers and people who like to tamper with websites they frequent by injecting additional javascript to manipulate the DOM.
Add in any javascript you like and it will automatically be executed everytime you visit the website in the future.
jQuery 3.3.1 is pre-loaded, so you can use all the $ magic immediately!
