Why Chrome Manifest V3 Compliance Matters
Chrome's transition to the **Manifest V3 (MV3)** architecture restricts extensions from running externally hosted code. Older, non-compliant extensions utilize Manifest V2 (MV2), which allows background scripts to inject hidden trackers that slow down your browser, log your credit card details, and expose your cookies. Sourcing extensions like GP Sourcing are written natively in Manifest V3, guaranteeing light local script execution, fast page load speeds, and strict cookie security.
Bypassing the 1688 Slider Validation Wall
When running multiple image searches, the 1688 platform will occasionally lock your screen with an anti-scraping slider verification (滑块验证). Follow these configuration steps to prevent search failures:
- Keep an Active Session: Open a separate browser tab, navigate directly to 1688.com, and ensure you are logged into a registered buyer account. Sourcing extensions rely on your active login cookies to execute searches.
- Solve the Slider Locally: If the slider appears, drag it manually on the official 1688 page. Once verified, the anti-scrape protection will whitelist your IP address for the next 2 hours, allowing your sourcing extension to run smoothly.
- Avoid Scraper Loops: Avoid clicking image search buttons in rapid succession (under 3 seconds per click) to prevent triggering the platform's rate limits.
