My manifest looks like this:
{
"js": ["JS/jquery.min.js","checkUser.js"],
"matches": ["https://www.instagram.com/*/"],
"run_at": "document_start"
}
However, checkUser.js is always running when I'm on any sub page. I want to it to be running when it is having only one placeholder between the two slashes, such as "https://www.instagram.com/user1/", "https://www.instagram.com/user2/" and so on. Is there an efficient way to do this?
