PS: Actually, it asks me frequently, no matter what I'm doing.

Same thing here. Is it genuine, or something harmful?

Anybody?

Firefox 3.6.4 provides uninterrupted browsing for Windows and Linux users when there is a crash in the Adobe Flash, Apple Quicktime or Microsoft Silverlight plugins.

If a plugin crashes or freezes, it will not affect the rest of Firefox. You will be able to reload the page to restart the plugin and try again.

Mozilla Firefox 3.6.4. The big new feature in this release is out-of-process plugins (OOPP). This means things like Flash, Java, QuickTime, etc., all run in separate processes, so when Flash decides to crash, it won't take your browser out with it. If Flash starts consuming all the CPU it can find, you can kill it without nuking your browser session. I've been using this feature since it was in the 'nightly build' stage, and it was still more stable than 3.6.3, just because Flash was isolated.

In other words, it's real and it's safe.

Just updated to FF 3.6.4 and am getting the same message all the time.

Yes ^^ Because they added a new feature...Of course you'd be getting the same message all the time.

I hate plug-in container. It's keep filling ram. So i'm going back to mozilla v3.6.3

You need to configure your firewall (or equivalent software) never to ask you again about plugin-container.exe. If you need help with that, contact the developer of the Firewall.

Also, if you are having problems with RAM and/or CPU usage, do this:

1. run Firefox in safe-mode to disable all extensions, themes and plugins. If this fixes your issues, be them with RAM or CPU usage, then you know it's a problem with plugins, themes or extensions. Proceed to number 2. If safe-mode doesn't fix the issues, then read bellow, after this list;
2. update all extensions, themes and plugins in your Firefox. If this doesn't solve the issues, proceed to the following number;
3. disable all extensions, themes and plugins in your Firefox (not running safe-mode). Being certain that, as in safe-mode, the problems you're having have gone away, enable one plugin at a time. You should be certain that you WANT that plugin to be enabled, so keep your overall number of plugins as low as possible. When you encounter the problems, you know you've found a problematic plugin, so disable it for good. Keep enabling all plugins (except problematic ones) until you've gone through them all.
4. enable one extension at a time. Again, be certain that you WANT that extension to be enabled, so keep your overall number of extensions as low as possible. Also, try the theme you want to have installed so see if that is what's causing the problem. When you encounter the problems, you know you've found a problematic extension/theme, so disable it for good. Keep enabling all your extensions (except problematic ones) until you've gone through them all;
5. you're done! You've fixed your problems with problematic add-ons. If you want to keep using those problematic add-ons, please contant their author for support.

Ok, if disabling all extensions and plugins through safe-mode didn't work to bring Firefox's CPU and RAM usage to good levels, then you have different issue. The most likely scenario is that you have a third party software running on your computer that is messing with Firefox. Do as follows:

1. try reinstalling Firefox. No data will be lost. You can get the latest version for free at getfirefox.com. If that doesn't fix the problem, proceed;
2. do a virus/malware check on your computer. If this doesn't fix it, proceed;
3. disable all software running in the background that you don't want to have running in the background (in windows, this is done by pressing WINDOWS+R in your keyboard, typing "msconfig" (without the commas) and pressing enter. Now, under the "Startup" tab, you can uncheck the software you don't want, and reboot your system for changes to take effect. If you're unsure of what software you want running, ask someone with more experience). If this doesn't fix your issues with Firefox, proceed;
4. check your firewall/antivirus/security suite for enabled functions/features that you don't want and/or may be conflicting with Firefox. You'll find that these features are most likely tied to Internet Security features, such as link scanners or URL checkers and the like. If you're not sure they are conflicting with Firefox, simply try to disable them to see whether or not that's true. As long as you don't browse the web with your antivirus completely off and your firewall completely turned off, there should be no problems. If this doesn't solve the issues, proceed to the following number;
5. check your operating system security options, mainly advanced options that are not configured by default. While it's very unlikely that this may be the cause of the problem (after all, it's the last item on the list), it's remotely possible. If this doesn't work, proceed to the following point;
6. update your modem/router software. There have been some reports that some modem/router software may cause Firefox and other browsers to loose performance and/or stability. If updating doesn't fix your issue, try other versions of the software, if possible. If you need support with this, contact your modem/router manufacturer. If this doesn't help, proceed;
7. clean up your OS registry, using appropriate software. Make sure you've followed my instructions correctly, but if this all doesn't work, create a new Firefox profile (this can be temporary, of course) and see if the issues persist. Report here the results, so we can help you further.

Oh Lord. Time to switch to Chrome. It's been fun Firefox.

Hello Fed.

If you have a problem with Google Chrome, you need to contact Google, since they are the ones that develop it. Be mindful that the big amounts of RAM it uses up when browsing multiple tabs is not a bug, but rather a "feature" of Chrome. Also, be mindful that the impossibility of having many tabs in the same window is not a bug, but rather a "feature" of Chrome. Bear in mind, in addition, that the relatively poverty of add-ons for Google Chrome is not as much due to its age but rather to the impossibility of developing add-ons for it that are as rich as those for Firefox. Don't forget either that the fact that Chrome will send, by default, potentially private information to Google is not a bug, but rather a "feature" of Chrome. You may also end up finding the very same problems you found in Firefox, if those were due to careless usage of add-ons or an infected system. For any usability problems, you will need to contact Google directly, too.

Also, if you are using another browser out of spite or because you can't fix your problem with Firefox, I will remind you that Mozilla is a non-profit, public service organization, and, as such, doesn't have the same financial interests Google (or any other company developing a major web browser) does. Mozilla's objective is that you, the user, use the browser you want, be if Firefox or any other browser. If you want to use Firefox but can't, due to a problem, I'm glad to work with you the best I know and can to fix it. If you actually want to use another browser, then I'm happy that you finally found your "home", and my job is successfully done.

Of course, be sure to read my post above for help.

With all due respect I did Not have any issues with my plug-ins BEFORE plugin container. Now websites that loaded up no problem BEFORE the 3.6.4 update are now stalling as plugin container struggles and eats up cpu and ram. I appreciate you have to fly the flag for firefox, and believe me i love browsing with it, but word has to be sent back to the developers that there's an issue here and it shouldn't require your 12 step safe-mode, degree in computer science, fix to resolve. This update was a mistake it should be addressed immediately.

Cozzy, I understand your point, but you have to understand that browser plugins are made for the browser, not the other way around. You'll see that, for example, installing Flash for Internet Explorer doesn't install Flash for Firefox. That's because Adobe needs to shape their plugin for each different browser, depending on how the browser works.

Again, if you are experiencing some sort of incompatibility between Flash and Firefox, you need to contact Adobe for support. It is a problem with Firefox only if the problems remain once you disable all add-ons. If, as soon as you enable Flash, you hit problems, then it's a problem with Flash. Remember, plugins are made for the browser, not the other way around. Also, this is not a widespread issue, as the majority of Flash and Firefox users have no problems whatsoever, I myself included.

Morbus, I did not have these problems yesterday. I do today. Not due to any update by Adobe, but due to the firefox update. From my very limited technical ability (which most users of firefox have) I can only see the single cause to my issues - the latest update to firefox. I don't want to use chrome or opera or god forbid ie, I want to browse with firefox. Can you at least tell us that the issue is being looked into?

Cozzy, please read my post carefully. I don't want to get defensive on this issue, and I'm trying not to. The facts are simple: if you Flash plugin is not up to date, please update it. If you are having problems with Flash plugin enabled but are not having problems with it disabled, it's a problem with Flash plugin and you need to contact Adobe for support. It doesn't matter that it started happening after you update Firefox: Adobe needs to build their Firefox plugin for Firefox, not the other way around. If Firefox 3.6.4 is now incompatible with old versions of Flash, update your Flash plugin. If the up to date version of Flash plugin is still having problems, you need to ask who makes the Flash plugin to fix it.

Also, yes, there are some bugs in Firefox 3.6.4 that will be fixed in Firefox 3.6.6 (the next update). You may choose to stick with Firefox 3.6.3 while 3.6.6 is not released. But I doubt it will have any effect. Most of the issues that some users have been experiencing seem to be either because they do not have their Flash plugin up to date (Firefox has been developed with Flash 10.1 in mind, not (as much) previous versions) or because, paradoxically, the new Flash 10.1 is causing problems in their computers. There are some instances where Flash is known to crash in Firefox 3.6.4 when it shouldn't, and those are already fixed and will be released in 3.6.6, but, to my knowledge, there is no known bug with Firefox that causes plugin-container to clog up CPU and/or RAM.

Morbus you can **** off. FF has auto-updates and their new update broke my machine as well. Sites that worked fine the other day are now all broken. This is rediculous!

Anonymous, please read my posts with attention and you'll know what you should do. If you need help understanding my English, or any jargon in my posts, please ask and I'll explain it in a simpler way.

How about an easy way to revert back to 3.6.3? That would be helpful. Passing the blame on to others is not.

I cannot recommend you to use an outdated version of Firefox, I'm sorry. You may get it, if you want, from Mozilla's FTP servers, but, again, it is not recommended.

If you need clarification on the "passing of blame", as you put it, please read my posts with attention.

I don't give a *** if it's recommended or not. Plain and simple everything worked fine in the last version, but not in this one. Post the g** d*** link for 3.6.3 so we can all go back and be happy.
