Open in Browser

Offers the possibility to display documents in the browser window.

Open in Browser is a Chrome extension designed to streamline your document viewing experience by allowing you to open various file types directly within your browser window. Say goodbye to those annoying download popups that prompt you to select external applications for viewing documents.

Starting from version 2.0, the extension uses the latest WebExtensions API, ensuring compatibility and performance improvements. It intelligently handles files when the server sends an explicit Content-Type header, opening documents seamlessly. For cases where content type is unspecified, the extension provides options to control dialog prompts.

To enhance usability, manual configuration after installation can minimize prompts when saving files, making your workflow smoother. Open in Browser also offers a manual "Open in Browser" dialog accessible via the Tools menu for additional control.

Experience hassle-free document access and reduce interruptions with the Open in Browser extension, the perfect solution for viewing files swiftly and efficiently in your browser.

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.
