intermittant "connection reset" problem browsing web sites at home

"From your description of symptoms, I suspect a problem in Firefox, likely with an extension. You might start by using Internet Explorer on a few web sites for a half-hour to an hour. If no intermittent problems are noticed, then run Firefox in ""safe mode"" without any of your extensions enabled, for a half-hour to an hour. Again, if you don't notice any problems, it points to a Firefox extension.

Now run Firefox with extensions enabled and disable as many of your newest extensions as you can remember, or disable all of them to be safe. Then enable them one-by-one until the problem returns. Disable that extension and continue enabling the other extensions one-by-one. If you don't see the problem again, it is likely an interaction between that one extension you still have disabled and another extension that you enabled before the misbehaving one. Send a note to the extension author with a list of those active extensions and see if the author knows of a conflict or can discover a conflict with another extension."
