StickyTabs от Florian Frevol

PinStart is a lightweight Firefox add-on that enhances your browsing workflow by automatically restoring your favorite pinned tabs every time you open a new window.

With PinStart, you can define your go-to URLs — whether it’s your email, project dashboard, documentation, or social feeds — and the add-on takes care of pinning them instantly in every new browser window. No more repetitive manual pinning!

The add-on offers a simple interface for entering and managing the list of URLs you want pinned. Once configured, every new window you open starts with a clean, consistent layout — just the way you like it.

Perfect for developers, remote workers, or anyone who relies on a consistent set of pinned tabs throughout their day.
