Prevent Tabs From Loading Until Selected in Chrome

Firefox has a nice feature called “Don’t load tabs until selected”. This setting can be found under the “Tabs” section in Firefox’s options window. What it does is prevent tabs from loading in the background until selected by the user. This is useful if you have configured Firefox to automatically load tabs from the last session at startup, or when you load a previously saved browsing session into memory. By not simultaneously retrieving and rendering multiple pages, Firefox’s startup time and responsiveness is dramatically improved.

Google Chrome has no such feature but you can add this behavior via an extension called FooTab.

FooTab was inspired by the BarTab extension for Firefox. This was before Firefox natively supported “tabs on demand”. BarTab is now irrelevant and hence discontinued, but FooTab continues to serve Google Chrome, until Google chooses to incorporate this behavior.

FooTab has no UI or configuration boxes to speak of. Simply install the extension and forget. When you open a saved session in Google Chrome, the pages won’t be loaded automatically. You will see a message instead: “this webpage was blocked by an extension”. Shortly afterwards, the page will reload.


FooTab works only for the first 10 seconds after Chrome starts, blocking tabs that are not active from any web requests. After those 10 seconds the web traffic is restored and the extension only monitors the tabs that were previously blocked to reload them when they are activated.

The extension is not hosted in Chrome web store because the developer says he doesn’t want to pay the fee that is required to publish an extension to the web store. To install the extension, download the CRX file from this page and save it to the hard disk. Then open Chrome’s extension page and drag and drop the CRX file into Chrome’s window.

You might have to use another browser to download the CRX file, because Chrome blocks any attempt to download extensions from non-approved websites.


  1. This is a great tip for chrome browser users and I am loving the new advancements brought forth by Google. Especially, the new extensions being introduced on daily basis have been really great help for users worldwide. Personally, I use a chrome extension for GroupDocs Viewer to view my files and read old PDF e-books. It has proved to be a handy extension for me and I can also develop such extensions with the help of this article which is a valued resource for developers as well as users.

  2. Lazy Tabs is working fine for me.

How to Record CPU and Memory Usage Over Time in Windows?

Whenever the computer is lagging or some application is taking too long to respond, we usually fire up task manager and look under the Performance tab or under Processes to check on processor utilization or the amount of free memory available. The task manager is ideal for real-time analysis of CPU and memory utilization. It even displays a short history of CPU utilization in the form of a graph. You get a small time-window, about 30 seconds or so, depending on how large the viewing area is.

How to Schedule Changes to Your Facebook Page Cover Photo

Facebook’s current layout, the so called Timeline, features a prominent, large cover photo that some people are using in a lot of different creative ways. Timeline is also available for Facebook Pages that people can use to promote their website or business or event. Although you can change the cover photo as often as you like, it’s meant to be static – something which you design and leave it for at least a few weeks or months like a redesigned website. However, there are times when you may want to change the cover photo frequently and periodically to match event dates or some special promotion that you are running or plan to run. So, here is how you can do that.
