Marketplace Auto-Scroll Scraper

About

Features

- Auto-scrolls Facebook Marketplace for a user‑set duration with Start/Stop controls and live status.

- Optional search text input that navigates to Marketplace search results before scraping.

- Collects listing fields: `item_id`, `title`, `price` (currently detected via `฿`), `location`, `url`, `image_url`, and de‑dupes by `item_id`.

- Auto‑exports a CSV when a run completes; manual “Export CSV” on demand.

- Saves the latest CSV + row count + timestamp to local extension storage.

- “Analyze Latest Results” shortcut and a full “Price Insights” dashboard.

- Insights dashboard accepts CSV file upload or pasted CSV text and validates required columns.

- Computes price metrics: average, median, best deal, and IQR‑based outlier bounds.

- Adjustable outlier sensitivity, optional price floor, and histogram bin controls.

- Visualizations: price distribution histogram and price‑by‑year trend line.

- Segment‑by‑year table with count, average, median, and best deal.

- Full data table with filtering, sorting, and modes (all/valid/filtered/outliers).

- Warnings for low sample sizes or missing year data.

- Insights run fully offline and only use local CSV data.

- Minimal permissions and host‑scoped to `facebook.com/marketplace`.
