I have a MacBook Air that is behaving poorly with Chrome. Symptoms include:

  1. Chrome often giving the "Ahh Snap" error message for lots of different websites, this happens frequently with the Google search page, when I enter a query to search, it often crashes.
  2. The insertion point for entering text is slow to respond to a click to position cursor.
  3. Web pages are slow to respond, for example, clicking on a message to select it for deletion inside Gmail can take a long time after clicking. This can take 30 seconds at times. Sometimes, if I click again, I get the multi-colored rainbow spinning wheel.
  4. Craig's List and Garnet Hill pictures do not appear in Chrome.

None of these issues happen with Safari. I've confirmed that speed tests show excellent Internet connectivity. I've run the Activity Monitor and no process in using significant CPU percentage. I'm running OS X Lion.

Should I try upgrading to OS X Mountain Lion? Should I reinstall Chrome. Should I reinstall my extensions to Chrome? How can I best track down the issue?

I'd start by creating a new "User" in Chrome.

Chrome > Preferences: New User

This will give you a fresh start on preferences and extensions.

If the new user has no issue then you likely have a bad extension or preference.

Chrome and Safari are both memory pigs these days (in exchange for which they are wicked fast when they have enough memory). How much RAM does your Air have?

When you look at the Chrome console when images fail to load is there anything interesting there? Chrome > View > Developer > JavaScript Console


Deleting the "Default" profile seems to have resolved all the issues (per the Chrome help pages):

  1. Quit Google Chrome completely.
  2. Go to the Go menu > Go to Folder.
  3. Enter the following directories in the text field, then press Go. ~/Library/Application Support/Google/Chrome/
  4. Locate the folder called "Default" in the directory window that opens and rename it as "Backup default."
  5. Try opening Google Chrome again. A new "Default" folder is automatically created as you start using the browser.

    Open Terminal and type mv ~/Library/Application\ Support/Google/Chrome/Default ~/Library/Application\ Support/Google/Chrome/Backup\ Default and press enter. Commented Oct 1, 2013 at 2:53

Here's a Chrome's built-in NetLog (now net-export) tool: chrome://net-export/. It's a built-in page that will instruct you how to monitor a network activity.

About the tool:

A NetLog dump is a log file of the browser's network-level events and state. You may be asked to provide this log when experiencing page load or performance problems.

You can analyze the resulting log too if you wish.

    This may be the right answer, but you need to back it up with excerpts from specific Google support web-links that document what this does.
