I'm leaving firefox - it was good while it lasted - but i haven't time to sort this out. It wasn't broke, but by trying to fix it - they then broke it - ciao firefox

I get a firefox error saying I already have an instance of firefox open, but I just loaded it. So I have to kill the process firefox and container-plugin and then restart Firefox again to get it to come up. I have 3.6.4 and XP.

The plugin-container make my FF hang everytime. I need to use Chrome to see Flash or Silverlight now. If FF don't fix this problem or let me choose using the plugin-container or not. I will totally use Chrome and leave FF!!!

deleted You have one problem with firefox and you whine and want to use another browser? No one cares, use another browser and get a virus, go right ahead. Go complain to someone who cares *lol*

My version of Mozilla is 3.6.8 and I have my task manager always running for killing plugin-container.exe when my browser fails...

this forum is just for listing problems, not for finding solutions. I, too, am getting tired of FF's many small but annoying problems. I would like to know where to get some answers, if not here at the MOZILLA FORUMS.

I found the way to stop using plugin-container.exe from somewhere and it works.

Steps to stop plugin-container.exe process:

   * Open Firefox web browser.
   * Type about:config in the address bar and press Enter key.
   * A warning will appear. Ignore it and press the "I』ll be careful, I promise!" button.
   * In the Filter field type dom.ipc. Six preferences will appear for the filter dom.ipc.
   * Ignore first and last preferences. Toggle (double-click) each of the four remaining preferences to change the value from "true" to "false".

Explanation: The crash protection feature in Firefox 3.6 is enabled for certain plugins only. The four preferences that we modified here specifies four different out-of-process plugins. They are the the NPAPI test plugin, Adobe Flash, Apple QuickTime (Windows) and Microsoft Silverlight (Windows). These plugins are specified in a separate dom.ipc.plugins.enabled.<filename> preference by default is set to true. We can disable them by changing their value to false. And thus plugin-container.exe will not run. By default the preference dom.ipc.plugins.enabled is already set to "false". So, no need to touch it. The dom.ipc.plugins.timeoutSecs is also not important here as other values are false.
