FireFox Web Extension

In a previous post regarding the new web extensions there was the following text:

In case anyone missed it, we published an update to our Web Extensions installer a couple weeks ago. This release works on Chrome, Edge Chromium, and Firefox (though Firefox requires some manual fidgeting to enable it thanks to changes they made in their security model to prohibit automatic enabling of extensions).

 

I have the latest extensions installed, but I'm trying to figure out how to get the Firefox extension to work... can you provide a little more details on what you had to do to get this to work?  

Thank you.

The bottom line is that Mozilla made changes to Firefox a while back to prevent add-on/extension publishers from being able to silently install/enable add-ons without the user's consent.  If you look at their website/support forum, you'll find documentation that talks about the changes and options for configuring the browser through policies and such, but as far as I can tell (and through my own experimentation), there is no way to force the extension to be enabled.  Once installed, the user will be prompted and they can still choose to disable it. (Caveat: I was not testing in an environment where I was able to configure GPO's, so maybe there is an option for enterprises that I could not test/validate.)

As a user who actually wants the extension installed (I suspect many/most users would see a prompt and say "I don't know what that is - no thanks"), what I did (right or wrong) was to use the option in the browser to "Install Add-on From File...".  This allows you to browse to a ZIP, JAR, or XPI file and manually import/enable an extension.  On a hunch, I went to the folder where our installer installs the extension (C:\Program Files (x86)\Flexera\App Portal WebExtensions\Firefox\client@appportal.flexera.com on my machine) and zipped the contents of that folder (I called it AppPortalWebExtension-Firefox.zip, but I don't think it matters what you call it).

Then in the browser, I went to Add-ons (Ctrl+Shift+A) > Manage Your Extensions > Install Add-on From File... Browse to your ZIP file and open it, then follow the prompts to enable it.
