Crashes have occurred loading webkit's initial page, appleinsider.com and nearly every other page I have tried with any build since 9/17/16
Could you please attach some crash logs?
Created attachment 289751 [details] crash report
Thanks... latest build Version 10.0 (12602.1.50.0.10, r206360) no longer crashes.
Thank you for following up! Probably a duplicate of bug 162536.
