Installing a custom static theme

more options

I wrote a simple theme extension:

{

   "name": "Tomorrow Night",
   "manifest_version": 2,
   "version": "1.0",
   "theme": {
       "colors": {
           "accentcolor": "#282a2e",
           "textcolor": "#b4b7b4",
           "tab_selected": "#373b41",
           "tab_text": "#c5c8c6",
           "toolbar": "#373b41",
           "tab_line": "#373b41"
       }
   },
   "applications": {

"gecko": { "id": "tomorrow-night@carlos.me" }

   }

}

I'm able temporarily install it from about:debugging.

So I built a zip and tried to install it as an addon from a file. Without the applications key firefox says the file is corrupted. With the applications key it says it can verify its signature. I can't submit it for verification in AMO because it rejects it saying it's a theme extension which are not yet supported.

So what can I do with this extension? Can't install it locally, can't publish it, can't verify it without publishing.

How am I supposed to install this simple theme for personal usage?

That it *can't*, obviously.

I think I know a better place for you to pursue this question. It's a forum where add-on developers and folks from the Add-ons site answer questions (they rarely if ever visit here):

https://discourse.mozilla.org/c/add-ons/themes

I read somewhere that in the future Firefox will be able to remember and automatically load the extensions you now need to reload each session through about:debugging. I don't know if that's in Developer Edition today, or in Nightly, or not yet available at all.
