PR_END_OF_FILE_ERROR only happens after power outages, and occasionally after internet outages, and can't be resolved unless I have cable company send reset signal to my modem. I have tried every trick and trouble shooting recommendation I have found here and elsewhere on the internet and nothing else works.

Used to be I could clear my cache/cookies etc, do a PC restart, repeat that 2-3 times and the issue would resolve it's self but not in the last 6-12 months. My cable/internet company is baffled by this and can't explain it since it is a Firefox issue but it still takes me 30 mins every time to get them to just send the stupid reset signal because I know what I'm talking about. I wanted to send this to you in case there are others that also experience this and have a fix or are as frustrated as I am. We lose power often in the Midwest with storms.
