See http://bugzilla.mozilla.org/attachment.cgi?id=142927&action=view I am unable to reproduce this problem with the latest nightly builds on OS X (Panther) using both classic and modern themes. I'll test more on 10.2 and 10.1 shortly.

Also unable to reproduce with 10.2 in modern or classic themes. I've tested with new and 1.4 and 1.5 created profiles. I also tested the 1.7a release build.

OK. also tested on 10.1 and cannot reproduce with current nightly or 1.7alpha.

Mozilla Prefs Panel fails to render properly, even with the latest nightly build of 1.7.b (Mac OSX 10.3.3). Looks like same problem, new bug #.

It did not reproduce in my environment. see. http://bugzilla.mozilla.org/show_bug.cgi?id=236467#c4

I am able to reproduce this on Windows 2000. The preferences window (Mozilla 1.7rc3) will either open entirely blank, or it will not open at all.

This is a trancated list of file accesses as generated by the FileMon utility. (the list was much longer, but these were the only problematic entries) The list was generated at the moment of mouse-click on the "Edit-->Preferences" menu entry.

Creating a new profile seems to solve the problem

(In reply to comment #10) > Creating a new profile seems to solve the problem I concur. It appears that obliterating all previous traces of Moz. and building a new profile will also work for the Mac.

I've just installed Mozilla 1.7 under Windows XP Professional and have the same problem (first time the preferences dialog is empty and unusable, second time it will not display at all). Creating a new profile had no effect / doesn't help. My version: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7) Gecko/20040616

Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; de-AT; rv:1.8a1) Gecko/2004052008 OS X 10.2.6 same problem. 1.6 had an only-once phenomenon - you could not call up the prefs dialog 2 times. now everything is broken; the user profiles have no influence.

The OS should be set to All.

All the same with 1.8a4 Mac. removing the prefs.js file does not help anything. stripping prefs.js fron unnecessary lines also fails. waht now? ijust can not change my prefs!!!!

December 2004 - still empty...

Please do not set bugzilla blocking + flags. That is reserved for drivers@mozilla.org

The Following Fixed it for me Mac OS X 10.3.7 and Mozilla 1.8a5 Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; de-AT; rv:1.8a5) Gecko/2004112206 Find your profile directory. Delete the file XUL.mfl (Windows) or XUL.mfasl (Mac OS X / Linux). There should be a sub-directory called chrome. Remove everything in chrome. This will not affect things like your mail data or preferences. You will then need to re-install any themes/extensions you want using versions compatible with your application. after that it can use the preferences menue.

WFM Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.6) Gecko/20070802 SeaMonkey/1.1.4

Since I switched to Version 2.0 and there is no preferences tree anymore, the problem doesn't exist anymore.
