## Description

cronTab is a Firefox addon that automatically opens specified URLs in new browser tabs at times defined by a simple cron-style schedule. Users can configure the extension using minute, hour, and weekday parameters, along with URL input, allowing flexible periodic browsing triggers. The schedule format supports wildcards, ranges, steps, and multiple values for precise control.

For example, cronTab can open a webpage every weekday at 9:00 AM or trigger URL opening every five minutes during specified hours. Its cron-like syntax supports aliases for weekdays and allows easy scheduling for repeated URL checks or reminders. This lightweight extension enhances productivity by automating tab openings on user-defined schedules.
