Firefox 3.6.4: plugin-container.exe

Post by Ruhe on 23/6/2010, 02:16

After updating to Firefox 3.6.4 you have to add the executable plugin-container.exe ("c:\Program Files\Mozilla Firefox\plugin-container.exe") and plugin~1.exe to your existing Start/Run Access group of your Firefox sandbox.

Thanks for the heads up Ruhe. You may also want to add it to your allowed internet access list, unless you don't trust Mozilla!

By the way, this is apparently the reason for plugin-container.exe wanting internet access (although it's all a bit confusing):
http://forums.mozillazine.org/viewtopic.php?p=9527447&sid=b24baf62d2bb95a5eee8c9a315b99373#p9527447

The plugin container only talks to Firefox. If it is attempting to connect to the internet, then it's the actual plugin trying to make the connection.

The reason you're seeing it now is because plugin-container.exe is a new process that your Firewall doesn't have rules for. You didn't see this previously because the plugins were being run as part of the firefox.exe process, which already had permission to access the internet.

Yeah, I couldn't play back videos on Askmen.com, so checking Win 7's fw logs reveal TCP drops to remote ports 80 % 1935, so when I disabled the fw temporarily and ran the video, I ran netstat -ano from cmd line and traced the process to plugin-container.exe, then cloned the Firefox browser rule and changed the program to plugin-container. All is good now but too bad a second process related to FF needs 'net access.

ssj, looking at that thread you linked, it seems it needs 'net access for only Flash content, which might explain why only the videos were being blocked. Although I'm not really sure of this, it seems to be the case. It needs access to remote TCP 1935 for sure, but there were drops also to remote TCP 80. I will, just to experiment, restrict the rule a bit to only 1935 and see what happens.

Thanks wat0114.

Not sure if you caught this thread here:
http://www.sandboxie.com/phpbb/viewtopic.php?p=54043#54043

So long story short, allow your plugin-container.exe to access the internet!

Thanks, I hadn't seen that. Still if one wants to allow it as restrictively possible without breaking web content, then it seems from what little I've seen so far that remote TCP port 1935 is all that's required for it.

I notice when watching a movie online,the new process,plug-in-container exe, is using 29,036 k RAM (per task manager, XP SP3).

I don't feel it,I don't see it,but I don't like it!!

I am going to look to disable this new "perfect solution to a non-existent problem" via FireFox "about config."

You might see an improvement with Firefox 3.6.6.

Thanks,updated from 3.6.4 to 3.6.6.

Also,disabled the plug-in-container exe in Firefox,and removed its entries from Sandboxie start/run and access internet permissions.

All of the media I have tried,so far,plays well with no error messages.

I really never had a problem with player crashes cascading to crash the browser anyway,and as near as I can tell,plug-in container exe served
no security function,so no loss.

I updated to 3.6.6 and Sandboxie is working fine. I have never had crashes on
Flash videos but I think that the only reason for the container to be disabled
should be if you are having problems with it.
I am conservative so I dont like this changes but my browsing is fine and I got
use to seeing the extra process so everything is fine for me.
One thing that I am doing different than you guys is that I have only added the
container to the start/run restrictions and have not had any problems.

Bo, I tried adding adding it to only the start/run restrictions,and a lot
of media did play,but I still found some that would not.

They didnt generate any error message,they just buffered forever.

When I did enter the plug-in container to the access internet permisions,
they would play.

When you start to play a vid,and open task manger,and see plug in container.exe,
and then stop the vid,or even kill the tab it is running in,does the plug-in
container process remain open?

It did for me, at least for as long as I watched it.

Noor the plugin container process remains open until I close the browser. I dont
watch many sites with flash but I go very often to Youtube and to this point I
have not had any trouble because I have not allowed internet access.

Check out this post/thread for a site that does not play videos if you don't allow plugin-container.exe access to the internet:

Hi ssj100. I did try those sites before and I can play ESPN videos without adding the container to the internet access restrictions but the porno videos dont play even if
I add the container to the internet restrictions. Even allowing scripts globally on my NoScript, the video wont play on the porno site. In the past I have found sites that
play videos on FF unsandboxed but wont play them sandboxed. This might be one of
those sites. I know you can play those videos when you allow internet access but on my case it does not make a difference. Normally I block flash and only allow it on
Youtube so I have not found a site that IF I allow internet it would play.

Sorry to resurrect an old thread,but as the question pertains to
plug-in-container exe,it seems the best place.

Since disabling plug-in-container exe,in Firefox aboutconfig, I have been
getting random "Problem Loading Page Server Not Found" errors in FireFox.

This, with the current 3.6.10 version,and the previous as well.
Has anyone else disabled the plug-in-container exe,and if so,are
you noticing anything?

I can not see how this could be the problem,but I cant thank of anything different on my system,and my ISP speed issues seem resolved for now.

regards,
noor

Guys,I now thank I was in error about disabling plugin exe,being the cause of my Firefox errors.

Rather, I thank it was a DNS/ISP issue.

I set up a Open DNS account,and the errors are gone.

Plus,like the old song about the Kung Fu Fighters,I am now
"Fast as Lightning"!!

Haha, good to see you resolved the issue noor. I would have doubted that disabling plugin-container.exe would have caused any page loading issues anyway.
