How can I use Scratchpad to write to apache server's root?

I'm trying to use Firefox-Developer Edition (version 45.0a2) for full web-development on my server. So, I've tried using the "Scratchpad" editor, which is great with the Vim keybindings, to write/edit an html file on my apache server's "root" directory. Unfortunately, every time I save the file the permissions are changed from "-rw-rw-rw-" to "-rw-------", resulting in a permission error. The server is hosted on RedHat Linux, with the default umask of "0022". The "root" directory permissions are "drwxrwsr-x. root apache ". Is this an unusual way for web-development, using Firefox and its developer tools alone? I could relax the permissions on the server, however, since the firefox browser is, technically, still connected to the public internet, is there a security concern in doing this? I can't seem to find helpful relevant information that's specific enough to this type of problem, so I'm asking here. Or maybe there's a way to change an option within Firefox to accomplish this?
