I am having this trouble too. Plugin.exe is almost always at the top of my cpu usage list and it's getting annoying. If this isn't fixed soon, I am back to google's browser...for good. I have development and a biz going on this machine and I cannot allow this to keep up. It's seriously getting in the way.

I've got the same problem on one of my computers just after having upgraded to FF8! There are continual freezing FF about in twenty-thirty seconds after it starting. Java&Flash plugins are both up to date. I post last crash report ID's as well:

Please, give me a piece of good advice what can i do to make FF work properly?

fmDeveloper. In fairness, it was pretty obvious from the start that it was Flash. And it is a firefox problem if Flash is continually crashing in your browser.

You say that plugin-container.exe is supposed to stop firefox crashing when a plug-in crashes. However, this is not happening. When the Flash plug-in crashes Firefox is freezing.

So as much as you may not like it, Flash crashing is a Firefox problem.

FYI - a freeze is not a crash. If you really believe it is Firefox, capture a stacktrace using the instructions below (WinDbg), open a bug report, and someone will take a look. If you post the bug ID here I will take a look at it myself and CC some developers/other support people I know.

From your point of view maybe fmdeveloper. But to me a freeze is the same as a crash i.e. Firefox stops working. And my first post says freeze.

I don't know what it is. It looks like it's flash causing the problem but as far as I'm concerned, it's also firefox's problem if the browser keeps stopping.

Maybe it is just time to move to Chrome

I have the "freeze" here on my Mac and my PC. In both cases Flash is the culprit.

Maybe I'll go back to an older version of Flash, since this started when I updated all my machines to the most recent versions of Flash.

Damn Adobe for their crappy software ...

I started having this issue when I updated to FF 8. Maybe it's a coincidence and Flash is the problem. Or could be something about how Flash and FF 8 interact. What I do know is that I just went back to FF 3.6.24 and I was able to see a vid that was all spazzed out when I tried to see it in FF 8.

Curious to see what happens over next few days. With FF 8, could not go more than 1 or 2 days before things hit molasses stage and I either had to kill the plugin or reboot my laptop.

You totally rock! CPU went to ZERO! I have been blessed exceedingly with your brilliant mind. I needed your help today and you gave it to me. Thanks! Ralph

Not one issue since going to FF 3.6.24.

I'm going to stay away from FF 8 until this gets sorted out. Might even give Chrome a try. But after years with FF... But hey, trying something new is how I ended up a FF user years ago.

you can disable plugin-container.exe by typing about:config in your address bar. In the filter type dom.ipc.plugins.enabled and change the value of all these preferences to false. Restart firefox and no more plugin-container.exe

I'm getting fed up with Firefox. It use to be the BEST but now it crashes, takes up too much memory that its becoming so damn slow! What happened? Its that Damn plugin-container.exe and when they put add-ons on a web page instead of in the program. I'm either reverting back to an earlier edition or IE 8

read this article. it will solve your Flash freezing problems. You're welcome.
