<![CDATA[Blank window pops up, then disappears ...]]>Version: 39.0.2256.71 - Opera is up to date
Update stream: Stable
System: Ubuntu 16.04.1 LTS (x86_64; Unity)

Using one window, every 10-15 minutes or so a small blank "pop-up" window opens - is totally blank with no webaddress - then closes after 1-2 seconds.

haven't made any changes. Standard UFW firewall, no intrusions. Ubuntu is A-Okay.

Extensions installed are:
AdBlock
Version 2.57

Black Menu for Google™
Version 11.0.6

Ghostery
Version 5.4.10

Google Calendar
Version 3.1.1

HTTPS Everywhere
Version 2016.9.1

I don't care about cookies
Version 2.5.9

NoScript Suite Lite
Version 0.2.1

WOT
Version 3.0.0

Any ideas? Thanks!
