How to execute a js code on a list of websites?

Im trying to transfer my saved list from one instagram account to another, I have found a code that allows me to like the picture when im on that picture link in the browser. Now I have wrote a code in js that pulls the links from my saved pictures and have a long list of links of pictures I have liked on my older account. each link is separated by
.

What I really need to do is to find a way to visit each of these links then execute the like code automatically (around 300+ links) , I will be on my new account and that way i will transfer the saved pictures.
