TabBlock is a free Chrome extension developed by xconvic that aims to prevent the opening of new tabs. Designed for users who frequently encounter websites with pop-up ads, TabBlock offers a convenient solution to eliminate the hassle of unwanted tabs.

With a red icon, TabBlock actively blocks the opening of any new tab, ensuring a seamless browsing experience free from intrusive pop-ups. Conversely, when the icon turns green, TabBlock allows users to open new tabs freely, granting them the flexibility to navigate between different webpages as needed.

It is important to note that while TabBlock effectively prevents new tabs from opening, it does not block redirections to ads within the same tab. To tackle this, users can explore other extensions or simply use the browser's "back" button to navigate away from unwanted ads. Additionally, TabBlock does not interfere with normal advertisements, focusing solely on preventing the opening of new tabs.

Overall, TabBlock is a handy Chrome extension that effectively curtails the annoyance of pop-up ads by preventing the opening of new tabs. Its intuitive red and green icon system allows users to easily control tab behavior, enhancing their browsing experience.
