Popup appears for a split second when searching on The Pirate Bay using Firefox

[ghost]

When using "Medium mode" on uBlock 1.5.5 on Firefox 44, performing a search on The Pirate Bay lets in a popup for a split second before it disappears. As soon as the results page loads after performing a search, you can see a popup window appear and disappear. Shouldn't the popup be completely suppressed when using Medium mode?

No other blocking addons are installed.

Popup blocking can't be done in a synchronous manner, there is no blocking API which can guarantee the popup window won't appear.

Using the no-popups switch should help as the popups are killed as soon as they are fired, but still there is no guarantee

Another trick: block inline script for the site, the popup code is triggered by inline script code on the page (inline scripting is not blocked in medium mode).

if you add this filter: /?placement=*&redirect$document

it will stop the connection to the ad domain.

@jo2dan23 @gorhill Thanks for the pointers.

Couldn't uBO treat $popup as $document,popup? Then this request wouldn't be send. ❓

Network requests and notifications about new tab or window opening are two different code paths. There is no way to prevent tab or window from opening, there is no blocking API for this.
