Also can generate huge amount of traffic. It contains src attribute of <image> 
for example that include about 50000 of "./" repeats. Normally, simple path of 
255 symbols ("/" repeats) is accepted in src by firefox, but if change "/" 
to "./" repeats firefox can (possible)  ask server infinitely for actually the 
same dir. So that. But it works, firefox crashes, loosing all tabs opened (why 
still not fixed?????)

I don't crash, I get a javascript "out of memory" error. Memory usage does hit
the roof, but once the page is closed I get it back on the next GC.

May there is too much of string addition's? If you delete some of them script 
should work without javascript error and url should be passed to to browser, 
after all browser hangs or crashes.

fixed. i removed some of additions from js now it should work fine ). It may 
not crash firefox, because i don't have ability to install firefox :/
