At the moment, development of ports for Waterfox based on Firefox 140+ is on hold due to stability issues. If you want to use the latest custom firefox based browsers, consider these options:
| Name | Windows 8.1 | Windows 8 | Windows 7 |
|---|---|---|---|
| Mullvad Browser for Windows 8+ | ✅ | ✅ | ❌ |
| Tor Browser for Windows 8+ | ✅ | ✅ | ❌ |
| LibreWolf for Windows 8+ | ✅ | ❌ | |
| Zen Browser for Windows 8+ | ✅ | ❌ |
*unstable/needs additional fixes...
If you still prefer Waterfox, version 6.5.11 / 128 is not crashing, it is stable.
