I had a lot of ther stuff open with Firefox though.
That's interesting. Although my operating system is too old for the latest Adobe Flash version, the last or my second of my attempts had no other windows open, about 9 hours ago. It was a Microsoft error message that crashes the window and re-opens a new one on Verizon's news web homepage, which is my normal opening homepage
Is it a new or old denial of service? I couldn't tell you. I'll defer to others.
For reference
Running Linux here.
