User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:57.0) Gecko/20100101 Firefox/57.0
Build ID: 20171129230227

Steps to reproduce:

A popup appeared and tries to force me to install some extension. Can't close the extensions popup and can't close the window. The only way I've found to close it is to click Cancel and immediately Control+w. From Linux taskbak the x to close the window is missing.

This site appears every 2 weeks under a different domain and we have already a bug report about this.
I will look if I can find the bug report ...
