Closetab.email

This extension helps you close those extra tabs that you hesitate to close until you've read that page completely. Simply click on the extension and set a timeout within which you'd like to read the page and close the tab. This extension will remember it for you and send weekly reminders to get back to that page.

You can also optionally assign tags and turn on/off reminders per tag. No separate account needed. Just login with your existing google account and start using. It's that simple.
