Add-on for Firefox
Keeps track of daily routine websites and opens them in tabs.
This extension lets you organize websites by day and open them up simultaneously as part of your daily routine. This is really handy if you read sites that update on a regular schedule (like webcomics, weekly columns, etc.).
Potential future updates include:
- bookmark folder integration
- separating lists by time (so you can have a morning/afternoon list for a day, for example)
