Google Chrome Helper is appearing in Activity Monitor a dozen times and overall using a ton of memory. How do I curtail this? Most advice columns say to go to my plugins and check "Play on click", but Google updated the browser and this option is no longer available. What can I do?
Every "Helper" is either a tab, a subframe, a core Chrome process or an extension.
You could reduce RAM usage by uninstalling extensions, or just using less tabs.
I figured it out. It was eating up over 300% of my mac's memory and making my computer heat up like an oven even though I've only had it for a few months. To solve this I opened Activity Manager (located in the utilities folder in the applications), and control-clicked on the google chrome helper until I got a window (had to double click). At the bottom of the window there was a quit button and I clicked it and it closed it out and my chrome still works fine.
You NEED to disable Flash in Chrome preferences/advanced/content.
