This fix worked for me. I hope it will also help you stop or get rid of plugin-container.exe in Firefox 4. Did it worked? Don’t forget to leave a reply!
Why I wrote about Plugin-container? First, let me clear you that it is not a Firefox speed improvement hack. This simple fix takes care of a Firefox related process called Plugin-container.exe. This process was supposed to protect you from Firefox crashes. But lots of people find it useless, as it consumes a lot of memory (when more than one plugins run in separate plugin-container process) and often leads to a frozen browser. You can free a good amount of memory by getting rid of Plugin-container.exe. If you are running a rig with huge amount of memory, ignore this. This fix may help those who have a slower or low memory computer.
I published this to help Firefox users (Windows and Linux). If you feel like it is not for you, just ignore it.
Some users complained that Firefox is consuming too much memory. Yes, it is. Firefox 4 has memory leak problems. I will try to write an article explaining how to reduce excessive memory usage on Firefox. Stay tuned!
This works on Firefox 5 too! If you want to disable plugin-container in Firefox 5, follow the steps above.
All users of newer versions of Firefox (up to version 20) should modify just one preference value. Just follow the first 4 points (1 to 4) in the instruction above. Ignore rest.
