Cannot customize text editor in Windows

[Jesdisciple]

about:version will be at the end of this post. (Incidentally, someone lost their bash code in your about:version page.)

I found a setting at Preferences > File Types to select my favorite text editor, but I can't add entries to the list. I also can't use [right-click] > Custom to change an existing entry. I found the config file and hacked it to specify Notepad++, but the setting just gets overwritten.

I've been looking for a lightweight browser for a while now. Thanks for working on this. :)
