(Reporter: Anca, Unassigned)


[Affected versions]: 
- 59.0.2 (20180323154952)
- 60.0b7 dev ed (20180326164103)
- 61.0a1 (2018-03-28)

[Affected platforms]:
- Mac OS 10.10
- macOS 10.13
- Ubuntu 16.04 x64
- Windows 10 x64

[Steps to reproduce]:
1. Go to and log in
2. Click on the Hide advertisement  “ > ” button ( mid-right side)
3. Click on the Install button ( )

[Expected result]:
- “Search and Wider Mail by Yahoo” extensions dialog prompt is displayed.

[Actual result]:
- Nothing happens.

[Regression range]:
- This is not a regression, I can see the same behavior since this add-on appeared, Firefox 53.0a1 (20161121030224).

[Additional notes]:
- The error displayed inside the browser console is the following: 
ReferenceError: chrome is not defined: 
view-source: 7:138808
Moving to WebExtensions: General, although this might be a site compatibility issue.  I can't easily find documentation below that explains how sites would trigger an option to directly install from the site.  I'm assuming the "chrome is not defined" means Google Chrome exposes a "chrome" property on a global object somewhere.
Component: DOM: Events → WebExtensions: General
Product: Core → Toolkit
This sounds like that web page is using Chrome's inline extension installation flow:

That's not something that we support in Firefox.
