I've noticed that the "chrome/userContent.css" file doesn't effect the homepage anymore, but I'd rather do it through an addon. Is it possible to inject css into firefox's default homepage?

Hi Computer, you should still be able to restyle Firefox's built-in home page using rules in a userContent.css file. However, the page changes frequently, so your rules might need an update.

You might find help for what you want to do on the following site, since pre-release versions often are discussed there, or feel free to ask about what you need here:

As for using an extension, they don't have rights to modify very many about: pages, so if something like the Stylus extension doesn't seem to be working, you'll need to use userContent.css.

Note that there are two versions of the Firefox Home page, about:home and about:newtab. You need to specify both pages in a @-moz-document url-prefix block.

@-moz-document url-prefix(about:home), url-prefix(about:newtab) {
/* CSS code goes here */
}
