firefox 57.0.1 for android 7.0 randomly hangs on this website and at times hangs when i do a search for text. doesn't happen on other browsers like chrome, dolphin. when it hangs, it hangs the entire OS (asus zenpad 3s 10 running android 7.0) and none of the buttons (home, back, recent) work to get out of the browser. the only way to resolve it is to hard reboot it. here's the website: http://www.imaging-resource.com/PRODS/sony-a7r-iii/sony-a7r-iiiA.HTM
