User Reviews

User reviews show a mixed experience. Many praise Long Screenshot for capturing the entire page and being easy to use with minimal permissions, especially on long pages like YouTube comments. However, autoscroll is inconsistent and long-page captures can fail on various sites, sometimes producing white gaps or missing content. Compatibility issues appear on certain pages (Kajabi threads, SPAs, protected PDFs). Overall usefulness depends heavily on page type and site, with strong positives for some pages and notable flaws on others.
Pros
  • Full-page screenshot capability: captures the entire page as a single image.
  • Generally reliable and easy to use, with minimal permissions.
  • Autoscroll works in at least some cases, enabling long captures.
  • Very handy for extremely long pages (for example, long YouTube comment sections).
Cons
  • Autoscroll is inconsistent or unreliable across pages.
  • Does not scroll on certain content types/pages (SPAs, Kajabi threads, protected PDFs).
  • Long-page captures can fail, producing only the first screen or white gaps/missing content.
  • Some users report the extension does not work at all or is useless on their setup.
