Hi Verne, sorry to hear about the crashes. Is there any pattern to the types of sites where it happens? Your Firefox may have logged some data that would help track down the cause of the problem. You can submit that data to Mozilla and share it with forum volunteers to see whether it points to the solution. Please check the support article "[[Firefox crashes - asking for support]]" for steps to get the crash report IDs from the about:crashes page, and then post some of the recent ones here.
