Open sites list for a Chrome process on OS X
Chrome on a MacBook Pro laptop running OS X Yosemite (10.10.5) that I
was using became unresponsive. Activity
showed a Google Chrome process was using about 100% of the CPU
cycles. I wanted to see what web sites the process was accessing in the browser
tabs associated with the process. One way to do so is to double-click
on the Chrome process in the Activity Monitor, which will open a
smaller window showing information on that process. Click on the
Open Files and Ports
tab on that window. You can then copy the
information you see in that window into a file and, using
, extract all of the lines containing
the IP address of the system, which will provide a list of sites accessed by
the Chrome process.

High CPU usage by the Google Chrome browser on an OS X system
When I started using a MacBook Pro laptop running OS X Yosemite (10.10.5) today,
I found that the Google Chrome browser (version 35.0.1916.153) was slow to

You can determine what web pages a Google Chrome process has open by putting
chrome://memory in the Chrome address bar. Once you've identified
the relevant Chrome window/tabs associated with a process, you can close the
tab, or tabs, that may be associated with the process to reduce CPU usage.
If needed, you can also suspend a process
temporarily under OS X with the kill command.

ChromeCacheView - Cache viewer for Google Chrome Web browser
I recently overwrote a file with notes about a problem I had to deal with that
was residing on a web server by moving another file over top of it
accidentally. I was in a hurry to complete my notes so I could go to
bed; I thought about waiting until the morning to complete the notes,
but thoughit I could complete them in just a few more minutes, but when I
as a shorthand in a mv command, I didn't realize
that the second item on the last command line entry was the filename for the
file with my notes. I didn't realize what I had done until I tried to
view the web page with my notes from the PC I was using at the time for
the SSH connection to the web server.
Since I had viewed the notes in the Google Chrome browser on the Microsoft
Windows-based system I was on shortly before I overwrote them, I thought
I might be able to find a copy of the notes in the browser's cache. But
since I didn't grasp what I had done until I refreshed the page in the
browser, it was now too late to get the data from the Chrome cache, since the
cached page now just showed the "404 file not found" message due to the
file no longer existing on the web server. So I thought there still
might be a slim chance that I could recover the notes web page from
a Volume Shadow
Copy, i.e., a prior version of the file stored on the Windows
system. I thought, if I could identify the particular cache file used
for that webpage, there might be a prior version of that file
stored by the Volume Shadow Copy Service. I thought I could possibly
which is a small, free program that will allow you to
examine the Google Chrome web browser cache. With
that program you can view a list of all cached web pages and
view the cached copies of those pages stored on the system.
I was able to identify the particular file in the
Data\Default\Cache directory that held that particular
cached webpage. The file was
data_4, but unfortunately,
I wasn't able to find a prior version of the file. Though if you
need to examine the Chrome cache on a Microsoft Windows system, ChromeCacheView
is a very useful tool well-suited to that purpose. You can also put
chrome://cache in the Chrome addres bar to see a list of
URLs of cached pages, but ChromeCacheView provides many more capabilities
for operations on that list of cached items.

Restoring home and start pages in Chrome after installing Yahoo Messenger
After my wife installed the Yahoo Messenger Suite so that she could
chat with a friend using it, on opening the Google Chrome browser, the
Yahoo Search - Web Search
page would appear. She didn't want that;
she wanted to have google.com as her home page and to have a tab open to
that when she started the browser as had occurred prior the the installation
of the Yahoo Messenger software. She said she had chosen not to install
the Yahoo toolbar and not to have it make such changes when she installed
the software, so was irked to find her home page was "hijacked" to be
a Yahoo search page. I found that I need to change both her home page and
the start page for Chrome to put her settings back to what they had been
prior to the installtion of the software.

Chrome Memory Usage under Windows
Oftentimes I've found that a web browser is responsible for high memory
utilization or high CPU usage on a system. But determing what tab or tabs
is culpable can be difficult. Fortunately, Google provides a mechanism for
doing so within its Chrome browser. By putting
in the address bar in a tab within the browser, you can get details on
the total memory usage by all browsers open on the system and the memory
consumed by tabs within Chrome.

High Chrome memory utilization
Checking on the cause for slow performance on a Microsoft Windows system, I
opened the Task Manager
and saw that memory utiilization was high.
Clicking on the Memory
column header to order the list of processes
by memory utilization, I saw that the Google Chrome web browser was consuming
most of the memory; there were many Chrome tabs open in the browser.
I could see that the Chrome tab consuming the most memory was one consuming
937.2 MB of memory.
To determine what webpages associated with tabs open in Chrome are
consuming excessive amounts of memory or CPU time, put
chrome://memory in the address bar of the browser. That will
provide information on the amount of memory consumed by each tab open in
the browser as can be seen in this
example. Since the entries aren't ordered by memory utilization, you
will need to scroll through the list to find the tabs consuming the most
In this case, when I scrolled through the list I saw the tab that was
consuming 937.2 MB of memory had a CNN.com article open in it. When I went
to that tab I saw a "Shockwave Flash has crashed" message at the top of the
tab. When I clicked on "Reload", I saw that memory utilization for that tab
inreased slightly. Moving back to a prior page in the tab with the back arrow
resulted in the Task Manager then showing the highest memory
utilization for a Chrome process to be about half the 937.2 MB shown previously.
I closed the tab to free memory.

Displaying Google Chrome browser information with chrome://
You can reveal a lot of internal
browser information by putting
in the Chrome address
E.g., Google Chrome maintains its own internal DNS cache. You
can display the entries in that cache by putting
in the address bar for Chrome. When you do so, you will see information
similar to that displayed below:
Future startups will prefetch DNS records for 10 hostnames
|Host name||How long ago|
You will also see a page load count for web pages.
If you put
chrome://downloads/ in the address bar you
will see a list of the recently downloaded files and the URLs that
were used to download them as well as the dates on which the files were
You can view Chrome's history information showing a list of recently
visited pages with the days and times they were visited with
You can see information on Chrome's memory utilization, including the
amount of memory used by each Chrome tab using
chrome://memory. That will also reveal the
amount of memory used by other browsers, such as Internet Explorer
and Firefox, that are open on the system. E.g.,
is an example from a Windows 7 system where 3 tabs are open within
Chrome, one for Wikipedia, one for Google, i.e., google.com, and one for
chrome://memory itself, which is labeled "About Memory". The
tabs are identified by
Tab at the beginning of the name. IE
11 and Firefox 35.0.1 are also open on the system and so information
about their memory utitlization is also displayed.

other browsers on the system that can be used to access websites. Click on
When you do that, the
HKEY_CLASSES_ROOT\http\shell\open\command is updated as shown
below when the query was run before and after the default browser was
changed from Internet Explorer to Google Chrome on a Windows Server 2012
