Thanks for your help. I updated Chrome, which is the browser I use. It made a slight difference (The url box appeared everytime I typed a letter in the url field. As soon as I moved my cursor to the url field, it would disappear).
Then, I cleared my browser’s cache and cookies. That solved the problem. Sorry, I should have thought of that myself, as doing that solved other problems I’ve had in the past.
Thank you again!
