OneTab Home by Ansu Sam's

OneTab Home is a personal command center for Firefox designed to make the new-tab page useful for focused work, study, and everyday organization.

It combines your essential tools in one clean workspace:
• Focus timer with customizable focus and break durations
• Tasks for planning and tracking daily work
• Saved tab sessions for continuing research or projects later
• Quick notes for capturing ideas and information
• Quick links for frequently used websites
• Focus and activity insights
• Customizable dashboard sections
• Light, dark, and system themes
• Custom accent colors and display density
• Local data storage with export and import options

OneTab Home is designed to stay lightweight and keep your workspace close at hand without requiring a separate productivity application.
Your data is stored locally in the browser. The extension does not require an account or send your personal workspace data to a remote service.
This is an early experimental release. Features and the interface will continue to evolve as OneTab Home is developed.
