About:
Waterfox Classic is a modified version of Firefox designed to maintain support for legacy browser extensions that rely on XUL and XPCOM. It targets users and organizations that depend on older workflows and custom add-ons no longer supported by modern browsers. This version prioritizes compatibility with legacy web technologies over the latest web standards.

Key Features:

Support for legacy Firefox extensions (XUL/XPCOM)
Continued use of the older Gecko rendering engine
Enhanced privacy settings compared to mainstream browsers
Compatibility with older web applications and plugins

Use Cases:

Running legacy enterprise web applications that require NPAPI or older JavaScript features
Using classic Firefox add-ons for specialized workflows (e.g., legacy password managers, scraping tools)

Alternatives:

Firefox ESR – Firefox ESR receives modern security updates but drops support for legacy extensions, unlike Waterfox Classic.
Pale Moon – Pale Moon is another Firefox fork focused on customization and legacy support, but uses the Goanna engine rather than Gecko.
