Try going into TextFX / TextFX Settings and check 'auto close XHTML tags'. This makes it work in plain HTML files too. You may need to install it if using a newer version of Notepad++
Click Plugins > Plugin Manager > Show Plugin Manager
On the "available" tab check the box by "TextFX Characters"
Click Install
Restart Notepad++
Enable the auto-close XHTM features as described above.
The Hex Editor plugin was disabled for being unstable. This means that the plugin crashed Notepad++ in some situations. I encountered this problem myself when trying to save an edited file.
Earlier versions of Notepad++ don't have those problems with the plugin.
