I am not sure where to take this. I have reloaded comcast Infinity and Firefox multiple times. I also upgraded to Windows 10, but this was happening before. I keep getting shut down or notified about a "debugger" issue. and there is a box that appears that has three choices, Debug, continue, or cancel. If I cancel, the screen freezes. If I continue, everything runs for 5 minutes and then it does it again. If I open the debugger, It is all a bunch of computer stuff that I have no idea what to do with. Most times I have to open the task manager and end Firefox and come back in again. The debugger says http://oascentral.comcast.net/...c=1&cmcsa300tab=1&cmsa250bt=1&:0. Some times there are other messages. I am about ready to quit using Firefox as I have no problems with Google Chrome or IE.
