Reminder Tabs is a Google Chrome extension. When you have a tab open you can click on the Reminder Tabs button and have that tab automatically open at a later time. You can set it to open once at a later time, or daily, weekly, or monthly.
I made it because bookmarks never worked very well for me. I would bookmark a page and then never look at my bookmarks. With Reminder Tabs, the page will automatically open up later so I won’t forget about it.
This extension is just HTML, CSS, and Javascript which uses the Chrome Extensions API.
