^ Ping on all this.

Today is Friday and we're now less than 2 weeks away from Firefox 57 so
I'm still afraid that if we continue advancing at the same pace we'll
miss the deadline :/

Uzair: When do you think you will be able to answer to the comments I
sent on Monday?

anonym: When will you have a closer look at the code and probably
request some adjustment to Uzair? Any update on the ops around the
release of the extension(s)?

On my side, this week I added back the browser detection code
(dc65945c0e) and started integrating the new download page in our set of
installation instructions (web/14630-adjust-to-new-verification-extension).

It's quite tricky but I think that I'll have something to send over to
Cody for review over the week-end. Then I'll still have a bunch of work
on polishing the visual of the new page but I can do that last, after
all the rest is integrated and working fine.
