User reviews

Quick Source Viewer is valued for its improved and readable source code presentation, making it a helpful tool for developers. However, it requires page reloads after installation, which can confuse users. It cannot access Chrome internal pages, the Chrome Store, or local files, leading to access errors. Some functionality limitations exist, such as lacking support for Cyrillic characters, viewing image sources, or selected text. Despite these issues, many users appreciate its usefulness and express gratitude for the convenience it offers compared to built-in Chrome tools.
Pros
  • Provides a much better and more readable page source viewing experience compared to Chrome's default viewer.
  • Useful tool, especially for developers looking to view pretty-printed source code.
  • Works well on many websites and makes viewing JS and CSS easier and more educational.
  • Generally appreciated for its functionality and versatility across platforms, including some mobile browsers.
  • Users find it simple and effective after reloading the target page as instructed.
Cons
  • Does not work on chrome:// pages, Chrome Store pages, and local files, giving 'Access is denied' errors.
  • Requires users to reload pages after installation for it to work properly, which isn't clearly indicated in the interface.
  • Does not display Cyrillic symbols correctly and lacks support for viewing specific selections or image sources.
  • Some users find limited functionality and request features like highlighting meta tags or viewing inline script contents without truncation.
  • No support for Brave browser mentioned and occasional issues with the extension staying in 'Page Loading...' state.
