Why is plugin-container necessary?

why is plugin-container.exe necessary? It only causes problems with my browsing. I used to have no problems until this was added. I got away from Internet Explorer because it sucked and needed to be updated all the time. It looks like Firefox is starting to resemble that. Why can't you just make a browser that works well and leave it alone instead of highly suggesting we upgrade to the newest version of Firefox which seems like once a week now and causes more problems every time. I'm loosing faith.

Same problem for me, encountered numerous hangs with some sites like http://www.iht.com/frontpage.htm.
Thanks Steve, your solution worked fine for me.
However, I still cannot understand why this Firefox upgrade needs such a manual fix.

Why is plugin-container.exe involved in receiving email?

Why is plugin-container.exe involved in receiving email? The plugin-container.exe is activated and uses abut 20% of CPU while receiving email into my Outlook Express. I use Windows XP Pro on a desktop PC.

Plugin-container.exe is part of Firefox, not Outlook Express. If you are trying to fetch an embedded video in a message, that might use the plugin container if Firefox is your default browser, but for links and images I would not expect that to be used.

Why FF plugin-container.exe trying to capture my screen?

While I was using FF I got a warning message from my anti-logger saying that plugin-container.exe trying to capture my screen.(This happened more than 3 times in 1 week) and when I deny the process from capturing my screen, the flash player crashes. I'm using Win 7 starter, FF 24.0.

Why does plugin-container.exe start 15 times (and then stop) during shutdown (taking MINUTES to shut down)?

FF takes forever to close (minutes). When using process explorer I see that as many as 15 instances of plugin-container.exe will be opened during the shut down process. I think this means that a plugin is crashing. I disabled all of the plugins and it still happened (but maybe not so many times). An obvious answer is to leave FF open but that seems kinda dumb. I haven't seemed to be able to find this addressed anywhere. I am using updated Xp, on a many year old machine. Please help.
Thanks, John Rooks

Why does plugin container crash ONLY on city of wonder on facebook

When trying to load City of Wonder on facebook, I get firefox not responding, then it closes, and checks for a solution.
Then it tells me that a plugin container stopped working. Ive tried everything, as it works fine on my daughter computer with an older version of firefox, I have installed an older version 3.5.10 and it stilll happened, then I installed the latest version 3.6.10.
I went to the help section and updated the adobe reader firefox told me was out of date, still it happens...how do I fix it once and for all??
I searched the web for answers, but none work, its really frustrating!

Andrew -- I'm not a programmer, but I do have a few comments as a reader . . .
On my MBP, OS 10.7.1, Safari 5.1:
The bottom "About Covu" is not live. Spaces is, but then I get the planet and it just sits there.
Blasts just sends the background up to Blasts. No more information is available.
Same machine, using Firefox:
Same results. No Difference.

Why is plugin-container using 100 of cpu & over 700K of storage?

This started with 3.6.16 plugin container takes ever increasing storage & cpu % I have to keep killing firefox & restarting

Your "Plug-in Container" is corrupted.
download the following:
Flash Player for ActiveX (Internet Explorer)
Flash Player Plug-in (All other browsers)
Flash Player Uninstaller
Also, download these:
Shockwave Player Uninstaller
Shockwave Player 112 FULL installer (ther browsers)
You'll need to install Shockwave with the FULL installer for IE too, but there isn't a direct download for it. You'll need to go to: http://get.adobe.com/shockwave/otherversions/ using IE AFTER everything else is done.
Save all the files and close your browser.
Run the uninstallers first (both of them)
Go to: C/Windows/System32
Delete the Macromed folder.
Open your Registry Editor (Start>Run or press the Windows key + R and type 'regedit' [minus the quotes] and click OK)
In the Registry Editor, go to:
HKEY_LOCAL_MACHINE/SOFTWARE
Delete the Macromedia folder (Right click and choose "Delete").
Go to:
HKEY_CURRENT_USER/Software and delete the Macromedia folder there too.
Close the Registry Editor and empty your recycle bin.
Run the Flash Player installers, and then the Shockwave FULL installer you downloaded.
Lastly, open IE and go to: http://get.adobe.com/shockwave/otherversions/ to download and install the Shockwave FULL installer for ActiveX (IE).
For Firefox, I recommend FlashBlock (https://addons.mozilla.org/en-US/firefox/addon/flashblock/) It's prevent ANY Flash content from loading until you allow it manually. It can get to be a pain, but you eventually get used to it.

Why does plugin-container.exe so often crash when closing PDF files?

When I load multiple PDFs in Firefox to check their content for errors one by one, closing one PDF tab to reveal another PDF tab very often causes plugin-container.exe to crash, which means I have to reload each remaining PDF tab to view the remaining files. This of course defeats the purpose of opening more than one at a time, and actually adds about 5 times as many clicks to the whole process because I have to clear the error and reload each page, then it might happen again or might not. It doesn't happen every time I close a PDF, but about 1 in 4 times.
I realize I have two versions of Acrobat installed (Acrobat 9.5.5 and Reader 11.0.10), and thus two Firefox plugins, but for the record this same thing happens on other computers that just have Reader or just have Acrobat, so it's not an issue of conflicting plugins. Though I did notice you aren't allowed to disable just one or the other -- deactivating one deactivates both. At first it seems not to, but if you reload the plugins page, you'll see both are actually off.
Windows coughs up the following error report when plugin-container.exe crashes, but Firefox says nothing, I guess because the plugin-container is a standalone app:

Appreciate any help available in resolving this crash.

Somehow this bug came up on my radar yesterday later in the day: the first two comments indicate different plugins, and the third refers to the Acrobat plugin:
<blockquote>This seems to happen if Adobe Reader is used for displaying PDF documents (pdfjs.disabled set to true and Preferences > Applications > PDF to "Adobe Reader (in Firefox)"). Opening two tabs displaying PDFs and closing one crashes the other one. Was able to reproduce with Firefox 36.0.1 and Adobe Reader plugin "Adobe Acrobat 11.0.10.32". When I tried to reproduce it later again in the same profile (or on Nightly and Beta), the tab didn't crash.</blockquote>

Sounds like your issue, but it's puzzling that they got a tab to crash and in your case only plugin-container.exe crashed.

Why does plugin-container.exe hog so much cpu usage?

When FF is running with some application (ie flash or maybe shockwave) or some type of embedded function, the cpu usage for plugin-container is generally between 60 and 80 percent. This causes extreme lag and reduced functionallity. Quite frankly it is extremely annoying to have things run so slowly.

Why does plugin-container.exe not start up with Firefox 3.6.15 anymore?

I have Firefox 3.6.15, Firefox 4.0 RC1 and Pale Moon 3.6.15 on my PC. Even though each .exe file is in a separate folder, if I start up say, Firefox 4.0 RC1 for awhile and then close it and start up Firefox 3.6.15 my settings are messed up and I have to fix some of them. I just noticed in Task Manager that plugin-container.exe does not start up with FF 3.6.15 and FF 4.0 RC1 and Pale Moon 3.6.15 anymore. I'm not sure what I did to cause this. I even went into Mozilla's folder and tried to start up plugin-container manually, but it does not start up. I'm at a loss, do I have to do a clean install of three browsers to fix this?

Why does Plugin Container run twice or rev and hang things up?

For almost 6 months I've had nothing but problems with Firefox's plug-in container. Almost every time I try to play a game (especially on Facebook) everything starts hanging, my computer starts revving, and when I go to Windows task mgr there are TWO instances of PIC running! I have to either end them or manually end FF. Maybe a coincidence, but it seems to coincide, at times, with unresponsive scripts. I've had a close fried of mine (a very skilled and experienced tech) working on it, but can't seem to get @ the root of the problem. I can't find a solution here or anywhere else, and am starting to consider offering a reward to the person who fixes it. It's a '''ROYAL''' pain!

Why does "plugin container for firefox" suddenly adjust the volume on my laptop? It only adjusts the volume of firefox, but it lowers it to next to nothing. HELP!

As of just today, whenever i play a video in firefox, the volume suddenly drops to next to nil. The problem is that i didn't change ANYTHING. I looked at my volume control, feeling that something was wrong there. And it was. [http://s1207.photobucket.com/albums/bb465/Hagosha/?action=view&current=FirefoxErrorReport.png link text]
This is what i saw. I tried numerous times to change the volume back, and every few minutes it would return to what it was in the picture. Any ideas WHY it's suddenly doing this? Nothing has changed, but it just started today.

Try updating Adobe Flash to the latest version. Your current installation exposes your system to exploits. See http://www.adobe.com/support/security/bulletins/apsb11-12.html
You also need to update Adobe Reader. See http://www.adobe.com/support/security/bulletins/apsb11-08.html
Update links: 
* http://get.adobe.com/flashplayer/

The Java update is not a security issue, but does enable Java to improve performance in Firefox 4.0.x

Sometimes a plugin-container.exe instance starts hogging a ton of memory -- I would like to know which plugin is running inside that plugin-container without having to one-by-one disable the plugins. Which process called plugin-container.exe?

As described above, I have several instances of plugin-container.exe running, which is OK. It would make me feel safer to know which plugins are running inside each of these, since I would be better able to know whether there is malware running inside one of them, or which website might have made the process start hogging memory.
I am a power user, I usually have 80-100 tabs open, and of course it is hard to track the website or plugin down without having to waste a lot of time.
Could you provide in future releases this information?
Is it already available under one of the about: pages (e.g. config, plugins, memory, etc?)

Thanks Efreak! 
Maybe I was not clear. I usually have 4-5 plugin-container.exe processes running. I know now that the large one that hogs is the Adobe Flash player, but, for example I don't know which plug-in initiated the other plugin-container.exe instances. 
One of them actually says "googletalkplugin.exe" if you dig deep, which is OK. At least I know why the plugin-container.exe was started. But there are other instances that are just there and there is no way to figure out which plug-in initiated it. 
This would of course also help figure out if it is really the Adobe Flash plug in that is hogging all the memory, OR even if within Firefox in the about: pages one could figure out which TABS are using which plug-ins.
Like that you could freely choose to terminate the process directly, or close the TAB. 
1) What I am looking for is a way to determine which plug-in is running under which instance of plugin-container.exe 
2) Additionally it would be great to have a summary of which TABS are using which plugins (e.g. in the about:plugins page or yet another about: page)
 
Thank you

Plugin-container.exe : what is it, why is it necessary, can I delete it

Continued from the "plugin-container.exe : what is it, why is it necessary, can I delete it" thread:
1) When people say Firefox uses up a lot of CPU/Memory, they are telling the truth. Tools like Task Manager and Process Explorer show you how much CPU/Memory Firefox is using up. Stop calling people liars when they say Firefox is using up X Memory. Stop making baseless accusations like "you're running other programmes that are causing your CPU to skyrocket and Firefox to freeze". Task Manager and Process Explorer don't lie. Take yourself off the thread because you're not helping anyone, you're creating anger and hatred, you're basically trolling. If you have no valid advice to offer, keep your mouth shut and stay away instead of launching into the "you're a liar" nonsense.
2) Stop typing in caps
3) Refrain from using profanity and ad hominem attacks
4) If you claim you're abandoning Firefox for another browser, fine: now get off the board and go away instead of posting inflammatory hatred against Mozilla since you're no longer using Mozilla
5) Stop attacking and/or ignoring the advice of Mozilla representatives like Morbus
6) Morbus: the Firefox Safe-Mode advice you frequently dispense is the most rejected advice because most people do not want to mess with their browsers, especially people who are not not knowledgeable about safe-mode, add-ons, disabling, etc. I fully agree that people must learn how to diagnose the problems on their own and find solutions on their own, but not all people are capable of learning how to do that. Computers are easy for many people, but not all people. The Safe-Mode solution appeals to a '''minority '''of people who are comfortable with picking apart their browser and picking apart other things to find solutions, not the majority, who fear making things worse.
== This happened ==
Every time Firefox opened
== Today 6/22/2010

7) Stop telling people to remove add-ons and plug-ins and scripts. Firefox was made specifically to enable to build their own browsers. Firefox was made for the purpose of allowing people use all the add-ons and plug-ins and scripts they wanted. No other browser offers that range of add-on/plug-in/script support. Removing the add-ons and plug-ins and scripts eliminates the purpose of Firefox. If Mozilla representatives want to insist that removing add-ons and plug-ins and scripts are the solution, then Mozilla is telling us that its browser is no different from IE or Chrome, in which case Mozilla has given us a reason to stop using Mozilla.

Why does FireFox freeze and the only way to unfreeze it is to open the task manager and close the plugin-container.exe file??? It has been happening more and more often and it is getting VERY AGGRAVATING!!!!!

When Firefox does freeze (not responding appears in parentheses in the page tab) I am not able to access any of the webpages (the entire webpage is hidden behind a vaguely white transparent foreground) and more often than not any files I might be downloading are stopped before the entire file has been transferred - which means that I have to start those downloads from the beginning AGAIN. This has been happening for quite some time and I AM SICK AND TIRED OF IT HAPPENING!!
If it continues to happen for much longer I will swear off FireFox FOREVER!!!!! Either a program works or it does not work and lately Firefox has not worked worth a damn...........
The ONLY way to force Firefox to allow me to access it is for me to end the plugin-container.exe file process using Task Manager. Clearing there is a SERIOUS problem here that has not been resolved - why not???

The pluging container opens up unnecessary copies as the cookies/history are cleared, this is a known issue, it might be what you are seeing, and it is hoped to be fixed in some future release of firerox.
There are some hangs affecting some users, with symptoms being high cpu usage, occurring as bookmark changes or syncing is in progress, there is a work around for that.
Firefox hanging as you close it see:
*[[firefox hangs]]
* [[firefox is already running but is not responding]]
