High memory usage is something most modern tabbed browser are plagued with, we have shared the excellent FireMin add-on for Firefox to tame the situation, and here is an equivalent for Google Chrome.
Working on the same concept as BarTab for Firefox; The Great Suspender for Google Chrome makes unused tabs inactive saving computing resources. The addon . Tab suspension not only saves memory, but also aids in a snappier browsing experience as inactive tabs do not consume other computing resources.
The Great Suspender Unloads tabs and park the suspended tabs, this action is further configurable with a user-configurable whitelist and option to auto-suspend after a pre-defined period of time. Moreover, the session is saved as usual and suspended tabs are retained after closing and reopening of the browser, preventing tabs from auto-reloading on start.
