<div class="moz-cite-prefix">Both Tab Mix Plus and Tab Utilities
add-ons restore this behavior, exactly the way you want it.<br>
<br>
BTW, while they now implement their own methods for restoring this
behavior, I believe they used to set that specific preference
before (anyone correct me if I'm wrong, I don't think I am though
as I remember TMP broke for a while because of this change). So
you'd never get accurate data from telemetry about this
preference, as you wouldn't know if it was set through these
add-ons or directly in <a class="moz-txt-link-freetext" href="about:config">about:config</a>. If it was set through the
add-ons then that data becomes irrelevant as technically it's not
a "firefox feature" in this case.<br>
<br>
And they both provide this functionality as a full feature, with
its own dropdown box and everything to choose from the many modes,
rather than an obscure preference that only the very very savvy
would know about. Isn't that so much better than needing google to
figure out how to use that hidden pref, not to mention to even
find out about it? ;)<br>

There was a hidden pref, which I used. And even many
tutorials from internet tells use this pref, because
it makes closetab button more usefull (for some
users). Now this pref was completely removed, and
there is now different position of this buttons (on
each tab). So it's broke user experience for those
users who used this pref. It's told that nobody used
this pref. I want to check, if significant number of
users used this, or it was just me.<br>

You may just want to install my extension which lets you
customize this the way you want: <a
moz-do-not-send="true"
href="https://addons.mozilla.org/en-US/firefox/addon/readable-and-closable-tabs/"
target="_blank">https://addons.mozilla.org/en-US/firefox/addon/readable-and-closable-tabs/</a><br>

We have been actively removing support for hidden
preferences; in general, if you want a custom feature like
this, it's better to have it as an addon. That makes it
possible for things like safe-mode to disable the feature
if there's a problem; it also makes it possible for
Telemetry/Firefox Health Report/Crash Reporting to
correlate problems against particular settings, instead of
just having them as hidden settings.

The preference is now removed. Therefore telemetry
which compiled in binary release use source code where
is no such pref, and cant be measured it, right?<br>

That is actually not correct. If somebody has changed the
pref value, it will continue to be present in their
prefs.js file "forever", even though we no longer read it
in Firefox nor does it have a default value. So we could
measure this after-the-fact if it was important enough.<br>
<br>
Overall in this case, though, I don't think that's value,
and I don't think the data collected would change our
decision to remove support for the hidden pref.<br>
