Not in particular response to your actual problem, but...
Allegedly, on or about 23 April 2013, Beartooth sent:
I can't imagine anything I have being of interest to an intruder.
These days, it seems that miscreants have little interest in what's on your computer, but are interested in using your computer for their nefarious purposes.
My guess is that Arora had well over a hundred, but well under two hundred, tabs open when it crashed.
I really don't know how anybody does that, with any browser. On any computer that I've ever used, including other people's, the thing grinds to a sludgey halt when anything more than about twenty tabs are open, often far less. Especially with any pages that aren't just plain text. Scripts, Flash, even just lots of pictures, are the kiss of death. And, no, my computer isn't paging out to swap.
