What is plugin-container.exe?

The extension plugin-container.exe wanted access to the internet. The file was located in my Mozzile folder, but I read somewhere that it is malware. Is this file supposed to be there, and is it normal for attempt to receive a connection? Is it safe?

This happened

Just once or twice

== After the most recent update just a few hours ago.

Re: What is plugin-container.exe?

Go to the following link, click on "What's New in Firefox 3.6.4". The first 2 paragraphs is a brief explanation of what plugin-container.exe is designed to do. Right now, in Windows and Linux only, it isolates Adobe Flash, Apple Quicktime or Microsoft Silverlight plugins from the main browser, so that if one of those plug-ins crashes, your whole browser does not crash. This was done due to the large number of crashes caused by plug-ins. Plans are to add more plug-ins in later updates to Firefox.

Re: What is plugin-container.exe?

I would like to add to it, that it takes up 99% of my CPU and I lag so bad and have to wait a long time to use any of my apps that use Adobe Flash, ie: Evony. What can I do to uninstall it or fix it so I don't have so much lag?

Re: What is plugin-container.exe?

Plugin Container is hanging on me. Ever since I upgraded FF to 3.6.4 and Flash to the latest, Flash apps are causing Firefox to hang. It just freezes. Can't do anything but kill it in Task Manager. Then I get an error 'Plugin Container not working, search online for solution/close/debug'.

It's irritating. I think I will downgrade to earlier version of FF.

tl;dr

Plugin Container is causing browser to hang.

Re: What is plugin-container.exe?

But why does it have to connect to the internet when Firefox starts up in order to do this? I don't see the necessity.

Re: What is plugin-container.exe?

Connect to internet when u r using one of the 3 plug-ins it handles: Silverlight, Adobe Flash, Quicktime. If ur homepage has one of those, then it will start at Firefox startup.

Possible way to disable in about:config

Advise to backup prefs.js in your profile folder first, just in case.

If your browser crashes when a plug-in crashes, oh well, you caused it.

This set of posts answered my question about plugin-container.exe. Also, I told my firewall to Block access to the internet; so, it did not cause a problem for me.

Thanks

Re: What is plugin-container.exe?

Hello everyone.

If you have a problem with the plugin-container, you may be having a problem with some Firefox add-on that is hindering your Firefox's normal behavior. Have you tried disabling all add-ons (just to check), to see if Firefox goes back to normal?

Whenever you have a problem with Firefox, whatever it is, you should make sure it's not coming from one of your installed add-ons, be it an extension, a theme or a plugin. To do that easily and cleanly, run Firefox in safe mode and select Disable all add-ons. If the problem disappears, you know it's from an add-on. Disable them all in normal mode, and enable them one at a time until you find the source of the problem. See this article for information about troubleshooting extensions and theme. You can troubleshoot plugins the same way.

If you want support for one of your add-ons, you'll need to contact its author.
