Briefing

Hacker News: A new open-source browser extension called PageSieve enables users to scrape data from websites directly within Firefox.

Why it matters

Browser extensions for scraping lower the barrier for non-technical users to extract web data without writing code or using external tools. PageSieve's Firefox-only launch signals a niche focus, but its open-source nature and stated willingness to port to other browsers could broaden its reach if demand materializes.
