The story of web files began with the birth of the World Wide Web in the early 1990s, when the need to structure and share information across the internet gave rise to HTML, or HyperText Markup Language. HTML became the cornerstone of web content, allowing users to view text, embed images, and navigate through hyperlinks.

Over time, web files evolved to include supporting formats like CSS (Cascading Style Sheets) for visual design and JavaScript for interactivity, which worked together to create dynamic websites. As web content grew richer and more interactive, new file types were introduced to meet the increasing demands for functionality, multimedia integration, and cross-browser compatibility. These web-related file formats became essential to both the presentation and functionality of the internet, marking an important evolution from simple static documents to complex interactive platforms.
As browsers advanced and more features were introduced, users began to look for ways to preserve the exact appearance and behavior of web pages for offline use. Traditional saving methods, such as the “Save As HTML” option in browsers, would store the page and its components in multiple files and folders, which often led to broken layouts or missing images when accessed later. To solve this, developers began creating archive formats that could encapsulate all the parts of a web page into a single, manageable file. This led to the introduction of formats like MHTML (MIME HTML) by Microsoft and MAFF (Mozilla Archive Format File) by the Mozilla community. These formats allowed users to preserve entire web pages—text, images, stylesheets, scripts, and more—into one compressed file while maintaining the look and functionality of the original content.
The MAFF format was created as an extension for Mozilla Firefox during the mid-2000s. It was designed to give users a convenient way to save one or more browser tabs into a single compressed archive file using the familiar ZIP format. Each tab within a MAFF file contains a web page and all its related assets. Unlike other web archive formats, MAFF’s use of ZIP compression made it easier to examine or extract files manually if needed, and it supported multiple pages within a single file. This made it an excellent solution for researchers, journalists, educators, and anyone needing to archive or reference web content with full fidelity. During its peak, the MAFF extension was widely used by Firefox power users who needed a robust and reliable offline web-saving tool.
Other formats also emerged to serve different needs in the web environment. For instance, MHTML (.mht or .mhtml) was introduced by Microsoft to store web pages and their media content in a single file using the MIME encoding system. Though similar to MAFF in its purpose, MHTML was more commonly used in Internet Explorer and later in Microsoft Edge. Another important set of web files includes ASPX, PHP, and JSP, which are server-side files used to generate dynamic content. These file types handle backend processing and are responsible for delivering customized content to users. While not designed for offline use, they form the backbone of many modern web applications. On the client side, more user-focused formats like WebP (image format) and SVG (vector graphics) continued the trend of expanding what web files could represent.
As internet use continued to grow, so did the demand for web preservation, archiving tools, and offline access. Projects such as the Internet Archive’s Wayback Machine aimed to capture web pages across time, but individual users still needed tools that could allow them to save and manage their own browsing history or research collections. MAFF played an important role in this space by offering a simple, reliable, and portable method for offline archiving of web pages. However, after Firefox moved away from its legacy extension model, support for the MAFF extension was discontinued, leaving users with archived files but no simple way to open them in modern browsers.
This is where FileViewPro provides immense value. FileViewPro is a powerful universal file viewer that enables users to open and view hundreds of file types—including MAFF—without needing the original application that created them. With FileViewPro, users can open their MAFF files and explore the saved web content as if they were still viewing it in Firefox. The layout, images, and even interactive elements remain intact, providing a seamless way to access web archives that would otherwise be difficult to use. Whether you’re a researcher revisiting stored web sessions or someone exploring archived web pages, FileViewPro makes it easy to open and interact with MAFF files without needing technical expertise or outdated software.
