Firefox 56/Windows 10 crashing FREQUENTLY on www.washingtonpost.com, when attempting to access "comments" section. As is true with many sites, there are many handoffs and links flashing at the bottom before the "Comments" page fully loads. If one scrolls during this process, FF crashes. The page will restore quickly via the "Restore All Tabs" button in the Crash Report box, but chances are it will crash again two or perhaps three times before becoming stable. Rarely (today being an example), the page will crash FF without ANY user interaction, i.e., no scrolling. I've experienced this on only ONE other website; I visit perhaps a dozen each day reading news. FF stable on 95% of what I view. I've alerted the www.washingtonpost.com e-staff to this problem, but have not heard anything from them. The fact that it happened once on a different site leads me to believe its not a specific unique problem to the Washington Post, but there is something about that site that exploits a weakness if FF and causes crashes. Of course, every time it crashes, a crash report is sent to Mozillo. Perfectly willing to share other data... Just tell me how to get it to you. Oh -- I've completely reloaded FF once, and am currently running Windows anti-virus protection, plus recently scanned with Avast and Malwarebytes --- everything OK.
