Note 1
"Open 'about:preferences' in a window" is an experimental option that simulates a preference window, but internally is a default browser window with all toolbars hidden and the category tabs moved to the top.
This is not a XUL/preference window, so not every XUL feature applies here.
Bugs / restrictions / possible issues:

1. Leaving this preference window open and performing a browser restart will reopen it (like default browser windows are reopened after a restart).
2. It is possible this window is not accurate on every locale or in all HiDPI modes.
3. This windows size can be manually adjusted, but new dimensions do not get saved.
4. It is possible to shrink window size and corrupt its ui. There are no checks to forbid this.
5. Last opened category or tab does not get saved
6. Opening a second prefwindow closes the first one.
7. Keeping the window(s) after restart allows to open more of them,but there is no point in doing this.

Note 2
To the MacOSX 10.10 user who rapidly requests this add-on has to be signed: it is signed!
Add-ons only showed a ".1-signed" string once in May/June 2015 when Mozilla automatically signed them for the first time.
All add-on versions uploaded since then get signed automatically, but do not display a ".1-signed" string.

Validator / add-on signing
[change] internal changes to get rid of new validator warnings
[change] meeting add-on validators new rules
--> removed/changed/altered some features, see text below

Attention – important changes :-(
Most of you have heard of Mozillas new add-on signing process. As a part of this process, new rules (what add-ons are allowed to do and what not) were added to Firefox and Mozillas add-ons validator.
Some of these new rules forbid add-ons to change default Firefox preferences within a script/function like OS/Fx titlebar, ‘new tab’ page and tab clip width or (some) developer theme preferences, even if this is only done optionally after a user selects a corresponding CTR option. The result of this act is either play by new rules or not play at all, meaning either CTR drops supporting those features or no new CTR versions can be uploaded anymore. (I’m currently not even able to upload the already validated(!) and signed(!) version of CTR to the validator anymore).
I had to remove some CTR features to even being able to upload a new beta (!) version of CTR.
See screenshot: http://i.imgur.com/1Q3paEh.png

Explanation what changed (some preferences can still be altered manually through CTRs prefwindow):

• ‘New tab’ page: alternative ‘new tab’ page option will still modify the ‘new tab’ pages appearance, but switching between its ‘on’ and ‘off’ states will not be possible with one click anymore. Switching required modifying a default ‘new tab’ preference to true/false, but add-ons are not allowed to even offer switches for the default about:config preferences ‘browser.newtabpage.enabled’ and ‘browser.newtabpage.enhanced’ anymore. Having just a text (!) string as a label is already forbidden.
• ‘Tab clip width’ only affects ‘tab close on all tabs (forced)’ option. Its value will not get changed automatically to ‘1’ btw. ‘140’ anymore, but a new textbox allows changing this value manually now.
• Switching to ‘appbutton on titlebar’ will not enable Fx titlebar automatically anymore, if OS titlebar is active, but there has been always a switch for a change on CTRs prefwindow.
• Developer theme preferences on Fx35-40 have to be switched manually. Although Fx 40 (Aurora/DevEdition) handles dev edition theme inside add-ons manager, it still wrongly keeps the older developer theme preferences, which have to be disabled manually in some cases to not interfere with CTRs settings. Additionally the preference to prevent developer theme from being enabled had to be removed too (Fx35-40). Fx41+ is (currently) not affected by this.

If you do not like these changes, keep in mind I do not like them too, but they are necessary to keep this add-on alive. If you really need someone to blame for this, please use Mozillas default contact channels and report your thoughts about add-on signing and recent rule additions to them.
