Auto Tab Discard a lightweight extension that uses the native method (tabs.discard) to unload or suspend browser tabs to significantly reduce the memory footprint of your browser when many tabs are opened.
Enables organizing browser tabs into modular workspaces for project management, meetings, and workflows across Chrome and Firefox, helping reduce clutter, maintain focus, and access all resources or dashboards in one place, supporting seamless collaboration and context switching.
Efficient tab manager auto-closes idle tabs at user-defined intervals while saving them safely in the Tab Corral for later access. Offers comprehensive settings, Chrome synchronization, tab locking, and ensures pinned tabs remain untouched to optimize browser performance.
An essential add-on for power users that have many tabs open. Curb your resource usage by unloading tabs that you haven't visited for a while. An unloaded tab is restored back to its original state when you need it again.
If you tend to open too many tabs, closing them when no longer needed could be a tedious task. Fortunately you don't have to do it yourself.
This one also will automatically close your tabs, forcing you to rely on Chrome's crappy History function to retrieve them.
