When i view a video in firefox then close the tab half way through the video my network meter says that something is still being downloaded. In my avg task manager it says firefox is still using my connection. but also if I close firefox and its processes Resource Monitor on my windows still says firefox is using it but the application is closed. I have done a system restore but failed because I noticed this started in the last 2 days and the only thing I have recently install was adobe update. I have uninstalled firefox and re-installed it. also ran avg anti virus and malwarebytes

actually the problem came back and ur solution didn't work. I found that temporarily disabling avg protection stops the network from downloading. So that must be the culprit. Any suggestions fixing this?

This can be a problem with the plugin-container process.

You can check for problems with current Shockwave Flash plugin versions and try this:

  • disable protected mode in the Flash plugin (Flash 11.3+ on Windows Vista and later)
  • disable hardware acceleration in the Flash plugin

Is this a setting in the AVG program or in a Firefox extension added by AVG?

Is the plugin-container process still running after you close the tab with a video?


I've noticed that your System Details List shows that you have a user.js file in the profile folder to initialize prefs each time Firefox starts.

The user.js file is only present if you or other software has created this file and normally it wouldn't be there. You can check its content with a plain text editor (right-click: Open with) if you didn't create this file yourself.

The user.js file is read each time Firefox is started and initializes preferences to the value specified in this file, so preferences set via user.js can only be changed temporarily for the current session.

You can delete a possible user.js file and numbered prefs-##.js files and rename (or delete) the prefs.js file to reset all prefs to the default value including prefs set via user.js and prefs that are no longer supported in the current Firefox release or if there are only a few prefs set via user.js then you can remove the corresponding lines from the prefs.js file using a plain text editor like Notepad while Firefox is closed.

I don't know if its a setting in avg. the plugin container I would actually end that process in task manager and network would still be downloading. The user.js file I think is because I like Firefox to save my tabs when I close it to resume my last session. I'm gonna try re-installing avg to see if that fixes it. Thnx for ur suggestions.
