What’s new

Whatnot: The extension can run on whatnot.com with a dedicated bridge so you can post and fill listing flows from Sell The Flip.
Posting reliability: Updating and re-posting no longer tries to “delist” marketplaces where the listing was never actually posted, so the posting overlay behaves correctly for partially posted items.
Listings page: Search is smoother on large inventories (debounced search so typing stays responsive). Status tabs are reordered to All → Listed → Sold → Draft → Error.
Optional shorter line if you need a one-liner:
Adds Whatnot support, improves listings search performance and posting when re-listing, and fixes the update/post flow for never-posted marketplaces.

• Fixed a compatibility issue that prevented the extension from loading correctly on Firefox.
