You can still add friend to your friend but you cannot find that friend’s name through Steam. It is necessary for your friend to send the URL to you. Then, you can add friend through the website. The procedure to get the URL is as follows;
1. Tell your friend to go to profile page by clicking his/her name on the top.
2. Right click on blank space and choose Copy Page URL.
3. Ask your friend to send that URL to you. Then, you can add your friend immediately through web browser.
