Firefox browser is running slow? Too many processes when you use Firefox? If yes, you may need to get rid of Firefox plugin-container.exe process. You can easily do that by following my step by step guide to Stop Firefox Plugin-Container Process. Still no luck? Probably you are using Firefox 4. In that case, you need to follow some different step! In fact, many users asked me how to stop plugin-container.exe process in Firefox 4. This article is for those who wants to stop plugin-container process in Firefox version 4.
Steps to Remove or Stop Plugin-container Process in Firefox 4:
- Enter about:config in the Firefox address bar.
- Ignore the warning and go ahead by pressing “I’ll be careful, I promise!” button.
- Enter dom.ipc.plugins.enabled in the Filter field.
- One preference will appear. Change it’s value from true to false.
- Right click in the white space below Preferences Name.
- From the menu select Boolean under New.
- Enter new Boolean Value as dom.ipc.plugins.enabled.npctrl.dll
- Then enter the boolean value as false.
- Repeat the step from Step 5 to add the following preferences: dom.ipc.plugins.enabled.npqtplugin.dll, dom.ipc.plugins.enabled.npswf32.dll and dom.ipc.plugins.enabled.nptest.dll
- Look at the screenshot. Once all preferences are set, restart Firefox. Browse Internet as usual. Now you should see the difference!
Copy the 4 preferences from here:
This fix worked for me. I hope it will also help you stop or get rid of plugin-container.exe in Firefox 4. Did it worked? Don’t forget to leave a reply!
Why I wrote about Plugin-container? First, let me clear you that it is not a Firefox speed improvement hack. This simple fix takes care of a Firefox related process called Plugin-container.exe. This process was supposed to protect you from Firefox crashes. But lots of people find it useless, as it consumes a lot of memory (when more than one plugins run in separate plugin-container process) and often leads to a frozen browser. You can free a good amount of memory by getting rid of Plugin-container.exe. If you are running a rig with huge amount of memory, ignore this. This fix may help those who have a slower or low memory computer.
I published this to help Firefox users (Windows and Linux). If you feel like it is not for you, just ignore it.
Some users complained that Firefox is consuming too much memory. Yes, it is. Firefox 4 has memory leak problems. I will try to write an article explaining how to reduce excessive memory usage on Firefox. Stay tuned!
This works on Firefox 5 too! If you want to disable plugin-container in Firefox 5, follow the steps above.
All users of newer versions of Firefox (up to version 20) should modify just one preference value. Just follow the first 4 points (1 to 4) in the instruction above. Ignore rest.

Nice one Sandy!
Apart for FF running slow generally – it used to almost grind to a halt when writing anything in Facebook. It was so painful – AAARRGGHH!
But now… well – I’m going to blog/Twitter and FB your page here! :O)
This is a brilliant fix and should be shared with the world!

Thank you for this information, as I was looking for reason why Firefox 4 keeps crashing with Adobe Acrobat 10 and it’s driving me crazy. Excuse my ignorance, but before I go ahead and implement your advice, can you please clarify something – I am not sure if I do this, what happens to the plugins, will they work when I need them or are they disabled, I really don’t understand how it works. Thank you.
Sandy Official Reply on 4th Apr, 11 04:04am #
Don’t worry. Those plugins will work. This fix prevents plugin-container.exe process. All those plugins will run normally within Firefox and not in separate processes.
Reto on 6th Apr, 11 05:04pm #
It works like a charm !
When I installed FF4, a while ago, I wondered what was this plugin-container…
today made a search on it and found your explaination and solution !
Since then I configured it…
and FX is really much faster… :-)
Thanks a lot !
I suggest you contact Mozilla and tell them to have that fix on their plugin page, it deserves it :-)

Just wanted to say thank you for saving my day! It works. But why only a few comments? Only these 14-15 people found it useful? I don’t think so. But there are some people who follows only the mass opinion. C’mon visitors. Leave your comments and help others.
Anne on 9th Apr, 11 05:04pm #
Your screenshot shows 4 entries but your directions create 5 entries. The extra entry not displayed in your screen shot is called
Is this entry supposed to be added making 5 instead of the 4 entries?…. and what is the “nptest.dll” ? Thanks for all your efforts. Anne
Sandy Official Reply on 10th Apr, 11 07:04am #
Thanks for your reply. I took the screenshot while adding the last preference so that users can see the right click options. You need to add 4 preferences manually. The first one (dom.ipc.plugins.enabled) is already there and all you need to do is change it’s value from true to false.
For your information:
nptest.dll is related to Netscape Plugin Application Programming Interface (NPAPI) test plugin
and the others:
npctrl.dll is related to Microsoft Silverlight
npqtplugin.dll is related to Apple QuickTime
npswf32.dll is related to Adobe Flash
Hope this helps.

Installed FireFox 4 a day or two ago. Today it hung – I could hear noise from PC tower – Task Manager showed plugin-container.exe process using 50-70% of CPU. Your directions didn’t play out exactly for me. All 5 preferences showed up once I typed the first one into the filter space. dom.ipc.plugins.enabled was already false; the other four were true. One at a time I selected each of the other 4, right-clicked in the white space, then clicked on TOGGLE in the drop-down menu to change them from true to false. Seems to have worked. Thanks for the help.
RobH. on 10th Apr, 11 12:04pm #
Thanks for your efforts to help users everywhere! I came here because my Firefox seemed to hang on Flash games my kids use. It would lock the whole computer and the screen would take on a white veil. I uninstalled Firefox 3.6 and upgraded to 4. Also the same for Flash. However, still the same problem.
Your solution sounds interesting, and I hope it works. Won’t know until the kids try to bring Firefox to its knees!

I had very confused of plugin-container.exe appears everytime when I was trying to login my e-mail account, not other time. I have doubt that it is a Virus. So I search Google & found your blog solution here.
Great, now problem is solved.

I don’t have those on my FireFox4 ….
Copy the 4 preferences from here:
Sandy Official Reply on 19th Apr, 11 01:04pm #
You don’t have them. Because those are actually not present in FF4. That’s why you need to copy and add them one by one manually. Please follow the instructions carefully and add those preferences.

Sandy Official Reply on 30th Apr, 11 06:04am #
You are using Mac. Right? That’s why the difference. On Mac, before you disable it, check if you are running FF4 in 64-bit mode. If you are running it in 64-bit mode, switch to 32-bit mode. To do that exit Firefox. Control-click the Firefox.app icon. Then select “Get Info” and check the box “Open in 32-bit mode”. Now try setting the preference values false.

I just followed your instructions to stop the plugin-container process in Firefox4, but now firefox.exe is taking up just as much CPU as plugin-container.exe was before. Any idea what I could try to fix this? I have about 10 tabs open in my browser window and am using Windows XP. Thanks.

Worked for me.
Thank you so much :)
Ernie Rael on 6th Jun, 11 11:06pm #
Thanks, I don’t remember having a problem with FF3.6+, but FF4 has had a cpu problem for me. Now, with multiple windows and multiple tabs in each, the cpu is quiet when all is minimized.
You mentioned an upcoming article about memory leaks. Has that happened?
Didi on 7th Jun, 11 04:06am #
I got rid of plugin-contaIner, but my firefox is not using an average of 90% CPU… mostly between 98% and 84%.
I look forward to your posting a fix for this.
I know I could use other browsers, but I hate all of them. When firefox runs well, it is golden. None of the others seems secure and all of them are clunky to work with.
Thanks for this fix! Great job on the instructions!

Thanks so much for the fix. Really too bad Mozilla screwed this up so badly; I had to stop recommending Firefox to everyone, simply because I don’t want to wind up having to make trips to all their computers to fix this. I’ll use it; but for everyone else, by by Firefox, hello Chrome. The average person isn’t going to fix this themselves. They’ll just move on to another program. Sad, Firefox used to be so good. Now it’s just another broken program that sucks.
T.C. on 12th Jun, 11 11:06pm #
FF4 is back to it’s old speed. Thanks for keeping me from going to another browser. Now if Mozilla will fix their fix, we can all be happy little FFxes again.

I tried this in Firefox 6, but it seems the same as before. Actually now it’s slower than before and it takes a while for firefox to switch to another tab after I clicked it. The plugin container is gone, but firefox seems to be taking up most of the CPU whenever I’m playing a flash video (not youtube videos though, they seem to work fine). Maybe I should just try it in firefox 4 huh XD Thanks though. :D

For the folks asking about FF 6 and above, I use 6.0.2 and simply toggled the “dom.ipc.plugins.enabled” preference to “false.” It was set to “true” before I changed it. This has corrected the slow down problem for me. Hope it helps.

Could you please tell me if my issue would be caused by the Container or shall I further look for it somewhere else?

Wonderful, quick fix that works. I’ve noticed the plug-in container.exe for sometime but they’ve never been a problem until today when fast as I cleared them with the task manager, they came back. Couldn’t run anything, I thought it was my Trusteer Rapport that my online bank recommends but I think I may have been wrong.

Do I still need the plugin-container.exe for FF 11.0+?
Sandy Official Reply on 19th Mar, 12 06:03am #
It is still there in Firefox 11. If you face any problem with plugin-container.exe, you can disable it. No security, privacy or stability issues involved here. Also, you can revert back anytime to original FF settings.
For that, you can simply toggle the value for dom.ipc.plugins.enabled (it is already there, no need to enter a new boolean) to False.

Am I trying to sell you something? Am I asking you to buy a new computer? What you mean by nonsense or conspiracy? Can you explain please?
Users are facing this problem and that’s why they are coming to this page via Google and other search engines. The tip in this article involves a simple tweak of Firefox default settings. No registry changes, no instructions to use new software. Moreover, one can easily go back to default firefox settings. Now where you saw conspiracy?
John on 7th Oct, 12 08:10pm #
I think Snake99 was talking about the plugin container problem itself, not your fix for it. You have to figure that when they are putting in a feature that they know uses a huge amount of resources, and which is completely useless for 99.9% of users, a lot of people (like Snake) are going to assume there is an underhanded motive for it.

Sandy Official Reply on 29th Dec, 12 02:12pm #
You are using Firefox 11. First search if dom.ipc.plugins.enabled is present. If present make sure the value is false. If not present, right click on whitespace, go to New in the menu that appears and select Boolean. Enter dom.ipc.plugins.enabled in the preference name and set value as false. This should do.

20 and above you have to add these in, since they did away with the values and yet these ones are the ones beside flash plugin that cause so much havoc.

That is one sick techy trick buddy. Thanks alot. You should write tech manuals. The instructions were simple and easy to follow. Keep it up!!!
Andrew Reinbach on 19th Feb, 16 03:02am #
I just recently completely reloaded Firefox, so I have the latest version. Flash keeps loading automatically. Trying to follow your direction was impossible because entering About:config didn’t call up dom.ipc.plugins.enabled, or anything like it–just a very long list of preferences. Your step #4 did not appear, so “One preference will appear. Change it’s value from true to false.” did not appear. Thus I couldn’t get to the Boolean View, or enter any new Boolean value.I was also unable to unearth the four preferences to be changed–they didn’t seem to be on the list I got. In sum, About:config didn’t bring up any filter field in which to complete your directions. Can you offer me any advice?
Sandy Official Reply on 20th Feb, 16 07:02am #
Thank you for your comment. The problem is Mozilla changes firefox code frequently. The dom.ipc.plugins are no longer used. That means they have removed the option to disable plugin-container from about:config. Don’t know about others, but I don’t like it. That’s why I am using an older version of Firefox. Older version does not necessarily mean that it is bad or new versions are not always better. Sometimes they just load a bunch of features, which you can live without. If you are facing some serious problems, try to switch back to an earlier version of Firefox. Then disable plugin-container by using the above mentioned steps.

Aha ! Just as I thought I’d found the solution to the horrendous problems plug-in has been causing. dom.ipc.plugins.enabled isn’t in my list either. Plug-in is taking up 4x as much memory as firefox ! I’ve got Firefox V.49
Thanks for taking the trouble to highlight this.
