Daily Tab by Suyooo

This extension automatically opens tabs at a given time every day, even if the browser is closed at the time.
You can use this as reminders for sites you want to check for updates, or to launch sites for daily games such as Wordle.

After installing, open the extension configuration page via the extension icon (remember to check the extension overflow menu if you can't see the icon), and add timers there to set up sites to open at specific times.
Tabs will be opened in the background, so that your work is not interrupted, and by default will not load until you click on them. If you'd like for them to preload so the tabs are immediately active when you switch to them, use the "Preload" option. Note that this functionality is not supported on Firefox for Android, where tabs will always open up in the foreground.
