hi, I am using ubuntu linux. 

click ok after adding the url, it says
"javascript error, or parent window lost."

the same question popped up was posted in the forum 6 years ago and the only
answer was:

"Hum... I suspect some javascript+cookie+post mix.. 
this is rather indigestible for an offline browser, 
unfortunately. If the capture feature did not work, I 
don't see any immediate solution (if the javascript 
popup is sending some callback to the parent window, 
this is going to be REALLY hard to handle)"

I was wondering if there has been any progress in the meantime or if anyone
knows a solution to the problem
