What is waterfox-tray.exe?

waterfox-tray is the background tray utility for Waterfox that places an icon in the Windows system tray, allowing quick access to Waterfox settings, updates, and notifications without keeping the main browser window open. It runs continuously to monitor state and communicate with waterfox.exe, ensuring you can manage the browser from the tray.

Waterfox-tray is a lightweight helper process that manages the system tray icon, listens for update checks, and routes user interactions to the main waterfox.exe. It uses Windows API to render icons and handle notifications.

Quick Fact: Waterfox-tray was introduced to decouple tray functionality from the main browser, improving stability and responsiveness.

How to Tell if waterfox-tray.exe is Legitimate or Malware

File Location:: Must be in C:\Program Files\Waterfox\ or C:\Program Files (x86)\Waterfox\. Any waterfox-tray.exe elsewhere is suspicious.
