1393438 - Update 3rd party extension install permission doorhanger to match the rest of our permission UI

Status: RESOLVED FIXED

(Firefox :: Site Permissions, enhancement, P3)

The 3rd party extension install permission doorhanger looks quite different from the rest of our permission doorhangers and it's copy too doesn't follow the voice we are using on the other doorhangers.

This doorhanger shows for example when installing the 1Password Firefox extension: https://agilebits.com/onepassword/extensions/firefox

We should align this with the other permission doorhangers to improve users understanding of why they are seeing this dialog and how they should act on it.

Differences I noticed:
- Text should be phrased as a question
- url should be mentioned in the text, instead of listed on top
- learn more link should be provided after the text
- Confirm-Action should specify what it will allow (to not have to read the whole text.)

I propose to update the copy to 
Copy: "Will you allow <domain> to download an extension to your <browser>?"
Link: "Learn more..."
Confirmation: "Allow Extension Download"
and to remove to separate domain on top.

Michelle, can you please review the copy.

(For context: this doorhanger exist to prevent 3rd party sites from tricking users into installing an extension - they do not want - by getting them to click one button. As I understand security expects that clicking 2 buttons after each other can be expected to be more intentional and therefor safer. And users will understand that this is not the normal way to install extensions.)

When we start implementing this, we will need to create a SUMO page the Learn more can link to. I would hope for that page to explain about the difference between installing from AMO vs. installing from a 3rd party site.

Is this bug going anywhere? Does anyone want to ping Michelle on this?

The updated version of the extension install permission prompt matches the other prompts quite nicely and includes most of the changes requested. I think we can close this.
