The Great Suspender
Most of us open lot of tabs which are rather useless and memory hoggers.
The Great Suspender automatically suspends unused tabs to free up system resources.
To reduce memory footprint of chrome, the extension unloads, parks, or suspend tabs.
Tabs can suspended manually or auto-suspend after a configurable period of time.
To avoid automatic suspension, tabs can be whitelisted.
Very simple, easy to use and understand interface.
Searching for the right word or to find the correct meaning of a word, you need this extension.

Foreign words are automatically translated to your language of choice.
Browse simply to the page you wish to cite and hit the button to produce a correctly formatted citation.

Just send the content you want and not the distractions.
