Recently when I try to downloaed from the web I get a message: Plugin container for firefox not responding. Can I try to do something about it?
I did not instal the plugins separately. I believe they came with Firefox. I have Lenovo with Windows 7. The problem started a week ago, when I tried to save pdf files using the "save a copy" button. My Acrobat (professional latest version) works fine. I bypassed the first problem by using "Print" and supplied 'Acrobat' as a printer. It worked for a week, but now also this does not work. It does not arise for printing hard copies from the web using my cannon printer.

It is from Firefox, it is used to isolate plug-ins so that they would be less likely to crash Firefox and so that you could see what was using up your resources which could be the plug-ins or Firefox (maybe not quite the desired result).
You can terminate the plug in container through the "Processes: tab of the Windows Task Manger (Windows 7 shortcut to Task Mgr is WinKey+Shift+Esc) and it will be recreated when needed.
