Forever Tabs wót jmfallone

Firefox's built-in pinned tabs only restore in the first window on startup, and they're lost if that window isn't the last one closed. Forever Tabs is an opinionated change to this behaviour, where pinned tabs always appear on every window and do not get wiped depending on which session is closed.

Configure a list of URLs once, and they'll appear as pinned tabs in every new window you open.

• Pinned tabs appear in every new window automatically
• Your default new tab page is preserved
• No enforcement — close or unpin tabs freely in any window
• No data collection — your URL list stays local in browser storage
• Handles session restore without creating duplicates
