As of the moment, there's no way to completely disable ads from popping up, ctomblin.

As a workaround, you can enable the pop-up blocker in your browser. Here's how:

1. Select the lock icon to the left of the address bar.
2. Click Site settings (Google Chrome) or Permission for this site (Mozilla browser).
3. Hover to the Pop-ups and redirects section, and hit Block from the drop-down menu.

For Safari:

1. Open your Safari browser.
2. Select Safari, then click Preferences.
3. Select Websites at the top
4. Click Pop-up Windows on the left sidebar
5. Then hit Block in the pop-up menu for the website.
