I have been having this problem for months but nothing that I try will resolve it (I'm a trier but certainly not an expert!). I think that it is a problem with Shockwave Flash - or it started out as being that - but my pc 'hangs' at least two or three times a day. When it does, I go to my 'Windows Task Manager' and it regularly (but not always) shows that I have two "plugin-containers for Firefox" running. One shows a massive 'memory usage' and the other shows what I would estimate is a reasonable memory usage (I have taken screen shots which I have redacted to show only the relevant elements and will attach these hereto). In my attempts to resolve the 'hang' issue, I usually select the massive plugin within Windows Task Manager and hit the 'end process' button. Recently, I have been getting the message, "Bad News First: This Tab Has Crashed". Previously I used to get a message telling me that Adobe had crashed, refresh to resolve. In essence, that is (I hope) the problem explained but do please feel free to quiz me and I will try to give as much further information as I am able (ageing but willing, so to speak!) I thank you all/anyone in advance for any assistance which you are able to give. Best regards, Kev
