Chrome extension load a background.js each time the page reloads

Question

Can I reload the background.js each time a page reloads with my chrome extension?

I want to use it to inject a CSS file each time.

Answer 1

background.html - The background page, is only loaded once for each chrome session.
(I assumed that your background.js file runs from a background page, because of the file name)

• If you want to execute Javascript for each page, you have to use content scripts.
• If you want to inject static CSS in every page, have a look at this Stack Overflow question:
