on several websites but not all websites...

when disconnect is set to block the page, trying to print something causes a complete crash, aka the window disappears
this happens on some pages about 50% of the time, on some websites almost 100% percent of the time
when you unblock the page on disconnect, it stops happening

I can provide a log, but it doesn't look useful
