The feedback Mozilla is trying to gather on the usability of the
page could have been obtained using 'feedback' buttons.
If by that you mean that the web page could have a button that pops up
a form that people fill in and submit, this is nonsensical (if you
meant something else, please correct me).
A pop-up form is not an option for a non-JS page.
Why? There are various ways to make HTML&CSS-only popups, most of which
work in all modern browsers (expect maybe IE6/7, I'd need to test. Worst
case, we'd loose their feedback, big deal?)
You need to understand the constraints and then apply creative design
within these constraints. For example, a row of attractive feedback
buttons that work with JS disabled, and when JS is enabled zoom in on
these when leaving the page with a request to select one to leave a
feedback selection.
This is an atrocious user experience. When someone wants to leave the
page, they want to... leave the page, not give you feedback.
They may answer negatively just out of this frustration and there would
be no way to distinguish between this frustration and another
frustration. Also, a bunch of buttons is a very small amount of
information. Maybe not even a relevant one.
Among other things, human beings are both not fully self-aware (far
away from it, myself included) and irrational. The type of feedback
you get from observing how people do behave has nothing to do with
what people would say they do (only a fraction would give feedback, so
there is a "self-selection" bias and this fraction would say what it
thinks, not what it does).
The questions asked on the form also create a bias since they
necessarily direct the answers.
The very position and size of the button would create a bias based on
people screen size for instance.
I may be exagerating, but I feel a feedback button would mean lots of
time processing the answers where a statistical bias (well, several)
making any result questionable.
Listen to yourself. Observing how people behave while they are not aware!
I admit I haven't checked /privacy, but I can only imagine users are
informed there about this practice.
I'll repeat what I said elsewhere [1]:
"Note that a website is already capable to "track" every single click
(to other pages within the same domain) and know your navigation
patterns within the website. I'll go further by saying that this is
possible even without cookies (look for "web keys" or "capability URLs".
These weren't aimed at tracking, but could be use for that purpose).
I don't see how recording other clicks is that awful."
Every serious website has some form of HTTP logging (most often for
post-mortem security purposes). That's definitely some form of
"observing how people behave while they are not aware". If you're
uncomfortable with this idea, I'd recommend not going to any website
just to be sure :-/
More realistically, I'd recommend to inform yourself on common practices
of saving informations about users and wonder how much you're okay with
them.
Why even waste time on this. A simple HTML form would have sufficed.
I explained at length how much bias that would introduce thus making
this idea impractical.
The point is not to gather information for the sake and pleasure of
gathering information. This information is gathered to understand how
people use the website (and nobody cares how each individual
specifically use the website, the purpose is to understand trends,
overall reactions) and use this information to understand how to adjust
the website so people find more easily what they came for.
Or find another way. For example add an option to allow users to
choose to participate in an A/B choice.
That's an interesting idea.
