Hi, I want that all links open in a new tab, instead of editing those every single time.

Can I use the script:

function autoblank() {
    var links = document.links;
    for (let i = 0, linksLength = links.length ; i < linksLength ; i++) {
        if (links[i].hostname !== window.location.hostname) {
            links[i].target = '_blank';
            links[i].rel = 'noopener noreferrer';  // This is for security purposes
        }
    }
}
autoblank();

is it correct and Should I add it to my footer.php ? Is there a better option than that? Thank you!

Thank you!
