How can i see debug logs in web GL build

I recently downloaded the unity 5 beta (RC3). i managed to compile my code, run it in the simulator and build it for web GL platform. but when i run it out of the simulator i get an unexplained crush (chromes aw snap screen). Is there a way to get a crush report or the programs debug logs so i can get a lead on what happened ?

note: when i open chrome debugger i see nothing (the console is empty)

yes, in the build setting you should enable exception, this will show JS exceptions. regular logs will appear on console
