Error Uploading My Hours Calculator Extension

more options

Hi everyone,

I'm trying to upload a Firefox extension I built for my tool https://calculadoradehoras.io (an online calculator for work hours), but I’m stuck on the submission step.

I zipped the extension and uploaded it via addons.mozilla.org, but I get this error:

“Signing is not possible due to an error with the manifest file”

I double-checked manifest.json and everything seems fine. Here’s a snippet:

{

 "manifest_version": 2,
 "name": "Calculadora de Horas",
 "version": "1.0",
 "description": "Calculate work hours easily with this tool.",
 "icons": {
   "48": "icons/icon48.png",
   "128": "icons/icon128.png"
 },
 "browser_action": {
   "default_popup": "popup.html"
 },
 "permissions": ["tabs"]

}

I also tried switching to manifest_version: 3, but then Firefox Focus doesn't seem to recognize it properly.

Has anyone faced this issue while uploading extensions to AMO? Is there a specific guideline or manifest structure Firefox Focus requires?

Any help would be really appreciated.

Just to confirm, does it load and run locally through the About Debugging page? See:

https://firefox-source-docs.mozilla.org/devtools-user/about_colon_debugging/index.html#loading-a-temporary-extension

Note: I have no idea about Firefox Focus, just Firefox for desktop.
