Add-on not compatible with Firefox upon .xpi install attempt

I'm trying to publish my first Firefox extension and having trouble installing it.

I sign the package with jpm xpi. However, when I try to install the .xpi file, I get the error:

[extension name] could not be installed because it is not compatible with Firefox Developer Edition 52.0a2

I have also tried this in the consumer Firefox version 50.0.

Current em tags:

<em:minVersion>0.9</em:minVersion> <em:maxVersion>1.0+</em:maxVersion>

I have also tried 

 '<em:maxVersion>50.0.*</em:maxVersion>'

And

 '<em:maxVersion>52.0+</em:maxVersion>'

My current XPI file is hosted here

`<?xml version="1.0"?>

Any help would be hugely appreciated. I'm at a loss for how to proceed.

You are making a Firefox Add-on SDK extension. The install.rdf should be automatically generated for you when you execute jpm xpi from your package.json file. The install.rdf file that is shown above appears to have been copied from the example on this page and then edited by hand. In other words, it does not appear to have been automatically generated using jpm xpi. As such, it has errors.

Allow jpm xpi to automatically create a new install.rdf

You probably have that hand edited install.rdf file (and perhaps a bootstrap.js file) in the directory in which you ran jpm xpi. I suggest you remove the install.rdf (and bootstrap.js if it exists) from the directory in which you ran jpm xpi and permit it/them to be automatically generated by jpm xpi from your package.json. To have substantially the same information in the new install.rdf, you will need to add, or change, the following in your package.json:

"title": "Stop Normalizing Alt Right",
"fullName": "Stop Normalizing",
"version": "1.1.0",
"id": "[email protected]",
"homepage": "http://www.stopnormalizing.com",
"author": "George Zola",
