Open in Browser

Offers the possibility to display documents in the browser window.

Open in Browser is a powerful Chrome extension designed to enhance your browsing experience by allowing you to open documents directly within your browser window. Avoid the hassle of download popups and external application prompts when viewing files. This extension streamlines access by displaying supported documents instantly.

Version 2.0 and later leverages the modern WebExtensions API for improved compatibility and performance. While it may face limitations detecting file types without explicit Content-Type headers, you can manually force the open-in-browser dialog via the "Tools > Open in Browser" menu. Customize the behavior to reduce save-file confirmation prompts through easy preference adjustments. Open in Browser is an essential tool for anyone who frequently accesses documents online and wants seamless, within-browser viewing.

User reviews

Open in Browser is praised for its convenience in viewing various file types directly in Firefox without needing to download them, supporting formats like XML, audio, video, and YAML. It works well even with older Firefox variants. However, users report challenges with some RSS feeds and Gmail PDFs, occasional bugs in full screen mode on macOS, and concerns over privacy permissions. Despite these issues, it remains a valuable tool for seamless file inspection within the browser.

Very convenient tool to just viewing files directly in the browser instead of downloading! Useful to view GitLab artifact files and in many other situations too.
