6.6.0 Beta 3

macOS Auto-Update Bug

There is a bug in all previous macOS beta builds where automatic updates do not work. To fix this:

1. Download the latest beta

   • Download beta 3 DMG

2. Delete the BrowserWorks cache

   Option A: Using Terminal

   sudo rm -rf $HOME/Library/Caches/BrowserWorks

   Option B: Using Finder

   • Enable Hidden Files
   • Navigate to: Macintosh HD → Users → [Your Username] → Library → Caches
   • Delete the BrowserWorks directory

3. Install Waterfox

   • Open the downloaded DMG
   • Drag Waterfox to the Applications directory
   • Launch Waterfox

The update system should now work correctly! 🎉
