Plugin-container bug report

I'm having a problem that started in ver 9 and continues through 10.0.2. I use two plugins, Flash and RealPlayer. I also view pdf's outside of Firefox in Acrobat (not Reader). Each time i close a session of Firefox, the plugin-containers do not get killed. Also, Firefox will also start Acrobat with no open window when it closes. If I run a bunch of Firefox sessions without rebooting or manually killing the plugin-container sessions, they start to accumulate. I have had 10 - 20 running after a few days. And Acrobat is always running even though there is nothing showing. That doesn't seem reasonable.

That can be caused by clearing the cookies via "Clear Recent History".

  • Firefox/Tools > Options > Privacy > Firefox will: "Use custom settings for history" > [X] Clear history when Firefox closes > Settings
  • Firefox > History > Clear Recent History
  • Tools > Clear Recent History

If you use "Clear Recent History" to clear the cookies then Firefox also tries to clear the cookies from plugins like Flash (LSO) and starts a plugin-container process for each plugin and that can add extra time and can cause an unresponsive script error to appear.
