Distribution: Linux Mint 17.1 Rebecca

-- Information about the crash:
- Custom settings of the application:
Worked in Opera, then I start Firefox went to the page and then move Yandeks.metrika on page mouse wheel.  (mouse scrolling)   

As a result, the screen froze (stop scrolling). Then moving  jump to another position of a page, and where open this a failure-window 

Ват так всё и было! (Wat's the way it was!)
