How do I forces FF 23 to open maximized, not full screen, but maximized, both on start up and when opening new windows?

Question

Firefox 23 does not open maximized nor does it open new windows maximized. As such I have to manually maximize each window.
Run is set to maximized in the shortcut properties, yet it still opens in a normal or less than normal size window.
Older versions open maximized with no problem. I have Profile manager configured so that I can run multiple versions at the same time and everything opens maximized except FF 23.
is there some setting in the about:config interface or is this a genuine BUG in the latest version? Any help would be appreciated greatly.
Also can you tell me how to modify the title bar text/icon/etc as well as where to find the icon or portable network graphic (png) file for the main-window.ico or direct me to appropriate knowledge base articles for modifying both.

My localstore.rdf file was fine. The problem was caused by two plug-ins that Mozilla shows as being compatible with Firefox 23, when in fact they both cause undesired side effects.
Maybe the employees of Mozilla should actually test plug-ins before they allow them to be available for download or worse yet, recommend them.
And if any of the in-house developers had a clue they would stop removing old lines of code from Mozilla products so that new versions of Firefox would still be compatible with older plug-ins and extensions people would still like to use.
I had to remove recommended extensions and copy code from older versions of FF and NS and modify settings in about:config to allow older extensions to work to correct the problems and get Firefox to work the way I need it to. All in all I have over forty hours invested in modding FF at this point just to have it function the way it used to.
Unfortunately, since I still can't get buttons designed to open .URL links from the toolbar to work as they did in the past I have a feeling I'll be returning to older code sources to find more answers.
Lucky for me that I have every browser going back to NCSA Mosaic available to me, so every bit of code from the present till back before Mozilla existed is include in my knowledge base. It's a shame Mozilla doesn't keep such a reference available for it's users or apparently it's in house developers and staff.
Maybe I'll even re-enable the splash screen for Firefox since the only available plug-in for that doesn't appear to work with Version 23 either, even though once again the compatibility adviser says it does
It's truly sad that the result of Marc Andreessen's and James Clark's work and Netscape in general became the spawning Mozilla. What used to be a great browser and an acceptable replacement for Netscape, has become a joke. So much for all the hard work and effort made by Dave Hyatt and Blake Ross as well.
I guess that's what one should expect from the developers that are a part of generations X, Y, and Me. The attitudes associated with those generations show in the lack of thought, consideration, and ingenuity that have been a part the last several versions of FF, not to mention, the copying of features from Chrome.
When the only original idea to come out of Mozilla of late is to remove or disable features people have used and counted on for decades, the I don't care, I don't know, and me, me, me attitudes of so many from the aforementioned generations is truly evident in the last twenty incarnations of Firefox. Not to mention the attitudes and unhelpful nature of the responses users encounter when asking for help.
