It’s really hard to manage so many tabs on Chrome — and Firefox too. But worse still is the obstruction in the performance of your computer, as the tabs continue to run background processes and feed on your system’s memory.
Google Chrome likes to use memory and give your processor a good workout if you keep a handful (or more) tabs open on a regular basis. This can have a negative impact on the speed of your computer, and certainly the life of your laptop’s battery. The Great Suspender solves that problem by shutting those tabs down when they’re not in use.
New version 6.21 released.Bug fixes: Tabs no longer suspend with wrong url. Fixed ‘suspend other tabs’ buttonNew features: Dark theme for night crawlers. Improved whitelist with regex support. Suspend actions can now be performed on groups of highlighted tabs.
