I have had two encounters with
Plugin-container.exe problem with Firefox
. A few days ago, while using 3.6.6, my AVG identity protection came up, to let me know that I should use plugin-container.exe with caution, giving me two choices: to delete it, or to let me continue. I chose to continue, and have had no issue whatever.
My second encounter with with Firefox4.b2 prerelease. I was listening to music at NPR, and before starting, I had to allow plugin-container.exe, with my Firewall (Zone Alarm). Fifteen minutes later, the music stopped, apparently having crashed. I reallowed plugin-container.exe, this time placing a checkmark, not to ask again. So far, it seems to have been all I needed. Security software is wary of this new thing, but it is no big deal.
