PopupFilter

Prevents intempestive opening of popups from website links and scripts.

PopupFilter is a simple and lightweight add-on designed with WebExtensions API and compatible with Firefox, Chrome and Opera. The role of this add-on is to block/filter every tabs opened by web scrips or links (which can be hidden in front of page sometimes), even with context menu "Open in...". However, you can still open links in new tab normally by drag & drop links on nav bar or by switching temporarily to Normal Mode.

It's easy to switch between 3 different available modes :

• Normal Mode : Allow the opening of new tabs and new windows. (normal behaviour)
• Confirm Mode : Ask before opening and displaying content of new tabs/windows.
• Blocking Mode : Block all new tabs/windows opened by links or scripts.

PopupFilter contains also a settings webpage which enumerates open/confirm/blocked tabs and permits to do quick actions such as : close tab, display blocked content of tab, restore blocked tab, go to tab (double click). The main advantage and difference of PopupFilter is that it works without any black/white list and it does not retrieve your browser history or personal data unlike other classical popup blockers. Keep your privacy safe !
