Sell The Flip — List Everywhere version history - 17 versions
  • Be careful with old versions! These versions are displayed for testing and reference purposes.You should always use the latest version of an add-on.

  • Latest version

    Version 1.1.52

    Released May 31, 2026 - 134.5 KB
    Works with firefox 109.0 and later
    Reliability fixes for marketplace posting:

    • Mercari — Fixed a bug that could block posting even when you were logged in and connected. “New” items now post with the correct condition instead of being downgraded to “Like New.”

    • Depop — Unknown or unsupported brand names no longer cause a failed post; the listing is published without a brand when Depop’s catalog has no match.

    • General — Improved error handling and retry behavior when marketplaces return temporary validation errors.

    Version 1.1.51

    Released May 30, 2026 - 133.87 KB
    Works with firefox 109.0 and later
    What's new in 1.1.51

    • Clearer posting errors — When a marketplace rejects a listing, you now see specific guidance (sign in to Depop, reconnect eBay, Poshmark daily limit, Mercari site access, etc.) instead of raw technical messages.

    • Fewer repeated failures — The extension stops retrying the same error over and over in one session, so a bad permission or login issue won't spam failed attempts.

    • Smarter checks before posting — The Sell The Flip listing form shows a pre-post checklist (description, ZIP, eBay setup, and more) so you can fix issues before you hit Post.

    • Depop brand handling — Common brand names are resolved against Depop's catalog when possible, reducing "invalid brand" rejections.

    • Facebook improvements — Generic "Query Error" responses from Facebook are explained with actionable next steps.

    • Reliability fixes — Fixed a bug that could block Mercari posts even when you were logged in and connected.

  • Version 1.1.50

    Released May 26, 2026 - 128.46 KB
    Works with firefox 109.0 and later
    What's new in 1.1.50

    • Facebook Marketplace — More reliable posting for kids' clothing and similar items. We fixed cases where listings failed with a generic "missing or invalid field" error even when the title, photos, and price were correct.

    • Facebook Marketplace — Keeps your full title (including brand and character names like Disney or Minnie Mouse) when possible. The extension now retries with a compatible category in the background instead of asking you to change the title.

    • Smoother posting from the Sell The Flip website — Removed an extra "review marketplace settings" step when category auto-map confidence was low; mappings still run automatically before post.

  • Version 1.1.47

    Released May 26, 2026 - 128.46 KB
    Works with firefox 109.0 and later
    What's new in 1.1.47

    • Facebook Marketplace: more reliable cross-posting — fixes failures on pickup-only listings (including when quantity is greater than 1 in Sell The Flip) and on licensed character items (e.g. Dr. Seuss, Disney) by using Facebook-safe titles when needed.
    • Depop: invalid style tags (e.g. "shirt") no longer block listing creation — only valid Depop styles are sent, with automatic retry if Depop rejects a style.
    • Clearer error messages when Facebook rejects a listing for validation reasons.

  • Version 1.1.46

    Released May 26, 2026 - 124.36 KB
    Works with firefox 109.0 and later
    What's new in 1.1.46

    • Per-marketplace category, brand & color — set a default on your listing, then optionally override how each marketplace (eBay, Poshmark, Mercari, Depop, Facebook, Whatnot) categorizes, brands, or colors the item. Tap “Set specific marketplace category/brand/color” on the listing form when you need a custom value.

    • Smarter posting — if a marketplace rejects a category override, we automatically retry with the default mapping so your listing still goes out.

    • Whatnot → Mercari (and other cross-lists) — fixed an issue where photos imported from Whatnot could not be downloaded when cross-listing to other marketplaces.

    • Listing form polish — clearer “Default Category” label, inline eBay category picker, and dropdown indicators on marketplace category/color selects.

  • Version 1.1.44

    Released May 23, 2026 - 115.42 KB
    Works with firefox 109.0 and later
    Reliability improvements for cross-listing to Depop, Poshmark, Mercari, and Whatnot:

    • Depop — automatically retries when a listing is rejected for an invalid colour on category-specific items (e.g. collectibles).
    • Poshmark — automatically retries when a listing is rejected for an invalid color on certain categories.
    • Mercari — clearer in-app messages when Mercari requires payment setup or when your listing quota is reached.
    • Whatnot — more reliable background tab handling when posting or importing; retries if a tab is closed mid-operation.

    General stability fixes for marketplace posting. No new permissions in this release.

  • Version 1.1.43

    Released May 21, 2026 - 115.43 KB
    Works with firefox 109.0 and later
    What's new in 1.1.42:
    • Facebook Marketplace — clearer errors when a listing is rejected (Commerce Policy, missing fields, rate limits, or a rare API update). You’re no longer told to “update the extension” for every Facebook failure.
    • Mercari & Whatnot — more reliable background posting and clearer messages when a marketplace tab fails to load.
    • Mercari & Poshmark — restored “Fill form” from the extension toolbar popup on listing pages.
    • General reliability fixes for multi-marketplace posting from Sell The Flip.

    Released May 10, 2026 - 107.8 KB

  • Version 1.1.37

    Released May 5, 2026 - 107.78 KB
    Works with firefox 109.0 and later
    Fixed an issue where Mercari and Whatnot posting would fail with "Cannot access contents of the page. Extension manifest must request permission to access the respective host." The broad host permission (https:///) was triggering browser site-access restrictions for some users. Replaced with explicit per-site permissions. Also improved error messages across all marketplaces to show step-by-step fix instructions when Chrome/Firefox blocks extension access.

  • Version 1.1.36

    Released May 4, 2026 - 107.46 KB
    Works with firefox 109.0 and later
    Fixed an issue where Mercari and Whatnot posting would fail with "Cannot access contents of the page. Extension manifest must request permission to access the respective host." This was caused by a broad host permission (https:///) that allowed Chrome/Firefox to present users with a site-access restriction toggle. Removing the broad wildcard and relying on the explicit per-site host permissions resolves the issue for all users.

  • Version 1.1.33

    Released Apr 23, 2026 - 106.31 KB
    Works with firefox 109.0 and later
    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.
