Lubuntu / Epiphany flash issue
I've been happily using Epiphany for ages, and everything seemed to be working well. LAst week, Epiphany talked to Flash nicely, and played video clips. Today, it doesn't. If I try to play a clip, I'm told there is a missing plugin.
I have multiple browsers on this computer, and they play clips fine. The problem seem to be local to Epiphany, and arose in the last few days. Updates were downloaded the other night, and there was a disc check during boot today, but I don't see how this could have affected things.
Epiphany extensions are installed. I have tried removing and reinstalling. I feel I'm missing something simple. Tell me what it is.
