Opera browser required.
Tab Suspender extension automatically unload (kill/hibernate) inactive tabs. This action can free up your browser memory usage.
When there are too many open tabs, your browser needs to keep their data in memory; besides, background scripts are always running. Using this extension you can define a custom time-period for inactive tabs to go to hibernate state and hence do no use memory or any kind of resources at all.
Tab Suspender accepts following exceptions for your convenience:
1. Do not suspend pinned tabs
2. Do not suspend tabs that contain unsaved form inputs
3. Only auto-suspend if connected to the internet
4. Only auto-suspend if running on battery (if battery API is available)
5. Automatically unsuspend when tab gains focus

Es perfecta, apreciaria aun mas si viniera con la opcion de des-suspender automaticamente al enfocar la pagina.

As user @albertop8 has previously stated, this extension will erase many hibernated tabs if you disable/remove it, beware.

It just suspended a tab that I was using automatically. Also, there are tabs that won't be suspended when I "Suspend all tabs" or "Suspend other tabs" even though I didn't make an exception to that tab or website. Some tabs, when opening the browser, will turn into an about:blank page and will never unsuspend, and I can't workaround it if I can't go back a page.
This has made using Opera so much more stressful.

@muizzs: it's acting weird for me today too. It's been suspending tabs of whitelisted domains. It never did this before. Maybe a new version of Opera broke it?
