NoMoreTabs is an advanced guardian that stops websites from opening unwanted spam, betting, or ad tabs. It uses deep-interception technology to block hidden links in complex elements like Iframes and Shadow DOM, which basic popup blockers often miss. Key features include: - Ask Before Opening via a non-intrusive overlay. - A Smart Blacklist for permanent blocking of spammy domains. - A strict Zero Data Collection policy. You maintain complete control over what opens on your computer.
