Feature Request - Automatically Save Tabs When Pinned & Remove When Un-Pinned, Then Restore Saved Pinned Tabs When The Browser Opens

[WoofGrrrr]

Firefox loses all its pinned tabs when you accidentally close the 'wrong' window Bug 587400

This bug was opened 15 years ago. And it's still open. It seems to be stuck in a debate about what to do if there are multiple windows open with their own (different) set of pinned tabs.

But losing my pinned tabs is driving me crazy, and it's the only reason I'm looking at this and other extensions.

Manually saving and restoring pinned tabs is nice, but if you forget to save after you've pinned tabs, it doesn't really help. I'm looking for something that takes care of maintaining my pinned tabs automatically.

Perhaps...

1. Add the ability to have an 'AUTOMATIC' set of pinned tabs in storage to automatically restore when the browser opens
2. Automatically restore this AUTOMATIC set of pinned tabs when the browser opens
3. Use browser.tabs.onUpdated with filter {properties: ['pinned']} to listen for pinned & un-pinned events and automatically save pinned tabs to this AUTOMATIC set in storage and remove un-pinned tabs from this AUTOMATIC set in storage.
