How To Stop Firefox Lagging And Freezing...

This is a brief post on the simple fix that stops Firefox lagging and intermittently freezing.

It was driving me nuts and at first I thought it was a background program causing the issues until I checked Task Manager and seen a process called Firefox plugin-container.exe using a truckload of memory.


This new addition came in recent versions of Firefox to prevent browser crashes. Now FF loads certain plugins in a separate process (plugin-container.exe) to provide you uninterrupted browsing even when certain plugins stop working.

I’m sure it’s a great idea and all that but it really does seem to slow down browsing and creates annoying lags.

So, here’s how to put things back to how they were before and stop the plugin-container.exe process:

* Open Firefox.

* Type about:config in the address bar and press the 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 (dom.ipc.plugins.enabled and dom.ipc.plugins.timeoutSecs). Toggle (double-click) each of the four remaining preferences to change the value from “true” to “false“.

* That’s it. The screenshot up top shows how your setting should now look.
