The Great Suspender
is a free and open-source Google Chrome extension for people who find that chrome is consuming too much system resource or suffer from frequent chrome crashing. Once installed and enabled, this extension will automatically suspend tabs that have not been used for a while, freeing up memory and cpu that the tab was consuming.
Google Chrome is by far the most popular web browser in the world. But it’s not perfect.
If you have a lot of tabs open, you may notice your computer’s performance slow to a crawl. Many people have complained about it. A just-updated browser extension may help silence them, though.
The Great Suspender automatically recognizes tabs you’ve left open but unused for a set period of time and “unloads” them, replacing them with a simple screen that says “Tab suspended, click to reload.”
Tabs can auto-suspend after a configurable period of time or be suspended manually. Tabs can be whitelisted to avoid automatic suspension. Suspended tabs are retained after closing and reopening browser, preventing many tabs from all reloading after a restart. Very simple, intuitive interface.
You can make the experience more seamless by setting the extension to take a visual snapshot of the tab and automatically reload when you click it (although this uses up a little more memory, and, of course, suspended tabs won’t be able to send you alerts or retain any text you’ve entered).
You can also manually suspend tabs, either with a click or a keyboard shortcut, making for an easy and temporary alternative to bookmarking if you don’t want to go the auto route. Meanwhile, the ability to whitelist certain sites and keywords means you can configure for automatic tab suspension without preventing your email or Twitter feed from working away in the background.
