User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:53.0) Gecko/20100101 Firefox/53.0 I have tested this issue on Windows 10 x64 with the latest Firefox release (53.0) and the latest Nightly (55.0a1-20170425030221) and haven't managed to reproduce it. After downloading the latest version of Firefox and navigating to various websites, Firefox didn't crash or stop responding. Can you please add the error message you are receiving? Also could you add more details, if you like, share some of the websites where the browser has stop responding or a submit a crash id if the browser crashes. Could you also retest this using a new clean Firefox profile and also using the latest Nightly build (https://nightly.mozilla.org/)? You might be considering testing maybe even safe mode, in order to eliminate custom settings as a possible cause (https://goo.gl/AR5o9d). Thank you.
