Prevent New Tabs — Per-Site Popup Blocker troch Prevent New Page

Tired of websites constantly opening new tabs and popups you never asked for? Prevent New Tabs puts you back in control. Just click the extension icon on any website that annoys you, flip the toggle, and it will never open an unwanted tab or popup on you again.

Your settings are saved automatically — even after closing and reopening Firefox, the extension remembers exactly which sites you've blocked.

The free plan covers one website. Upgrade to Pro for $2 a month to block as many sites as you want, with a license key purchased directly from our store using PayPal or crypto.
