Currently Firefox is set by Windows to open .html files. I’m hoping I can sort of override this in FileZilla so I can do quick edits and then upload them to the server.
Solution:
In FileZilla go to edit > settings…
In the left column scroll down to “file editing”…
Select it, then in the right column select “use custom editor” then browse to the .exe file on your comp for Notepad++.
Hope it helps. 🙂
[Additional Note: if you are experiencing the same problem that @theking2 has in the comment below, remember that FileZilla also imports your system’s filetype associations. This may cause conflicts with your custom associations. You can disable system associations under edit > settings > file editing > Filetype Associations: look for the checkbox. Don’t forget that you did this though – it may cause other problems down the road.]
