Sticky password do not autologin in some website, username and password are filled in but Sticky password do not autologin.

For Waterfox Classic or G3 users, you need to install NativeMessaging windows registry key manually, so Sticky Password browser addon and Windows Sticky Password program can comunicate each other and Sticky Password program will detect Sticky Password addon on Waterfox so you can use it.

So do this thing.

1- Open notepad and copy the content I´m posting below and save it with .reg extension (stickypassword.reg). Make sure the path match with the one on you Windows installation of Sticky Password program.

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Mozilla\NativeMessagingHosts\com.sticky_password]
@="C:\\Program Files (x86)\\Sticky Password\\spNMHostMoz.json"

2 - Doble click on the .reg file you created to import the registry key.

3- Start Windows Sticky Password program.

4- Start Waterfox, if you already had Sticky Password addon, a pop up warning about "Sticky Password has blocked access from a new browser extension" will appear, press Allow. Otherwise proceed with the addon installation and when done the warning pop up will appear.

5- Enjoy using Sticky Password on latest waterfox Classic and Waterfox G3
