## Description

The Always Preview Chrome extension allows users to preview most PDF files directly within their browser using a built-in PDF reader. This functionality streamlines viewing PDF documents without needing extra software or downloads. However, the extension is now considered obsolete as modern Firefox versions include native PDF preview capabilities, reducing the need for this add-on.
