Google plans to add tab-under blocking functionality to the company's Chrome web browser in a future version of the web browser.
Tab-under refers to sites opening new tabs in the browser, for instance to display advertisement or get users to open third-party sites (often also to generate revenue from redirecting users).
The browser's popup blocking functionality does not prevent sites from spawning these tabs. It can happen that you encounter sites that take this to the extreme by launching lots of new tabs in the browser this way.
No modern web browser blocks tab-under popups at the time of writing. You may test your browser of choice by visiting this basic sample site.
You may click on "popup and then navigate" or "navigate and then popup" to test the functionality. The first launches the new tab first and then navigates to another page on the active tab, the second navigates to another page first and then opens the popup. The "other tab" is launched in the background regardless of method that you select.
Bleeping Computer reports that Google plans to put an end to the practice by adding options to the company's Chrome web browser to block the behavior.
According to the information, Google considered three different methods of dealing with the issue. The first two proposals would block the redirection and show an alert to the user, the third would improve the built-in popup blocker of the Chrome browser to add support for tab-under blocking to it.
The core difference between the first and second proposal is that the first method pushes the alert on the original page before the new tab is created, while the second would close the original tab and display the warning on the new tab.
Google engineers favor the first method according to Bleeping Computer, and it will be implemented in a future version of Chrome.
It is not clear yet when the feature will find its way into Canary and Development builds of the Chrome browser.
