I also have such problem (
Bookmarks bar/editor gone), but I aproximately understand with what is it about.
First, why this happened in my way...
I have many, too many bookmarks. Not only bookmarks, but also many sessions. And someday on another new bookmark (or maybe session) the bookmark editor window refuses to start normally. But in MS Windows taskbar there is bookmarks specific tab, but pushing it lead us nowhere - it just wan't open.
Second, where the problem lies...
Yes, i know how to partially fix this, but not very happy with it. So, there are several metods, if I'm not mistaken:
1) delete some bookmarks from file
bookmarks.html
2) renew file
prefs.js, -- but too many settings gone, and it's very sad.
But now, the first method doesn't work, works only second. And, as I said, it's not very funny solution. All this methods I'm not find very cool.
I looked a little through the settings of file
prefs.js and compared them with new one, changed some suspicious staff, but it's also didn't help.
If you want some settings from my file
prefs.js, here they are (as is - without my changes):
user_pref("kmeleon.plugins.bookmarks.editdialog.height", 848);
user_pref("kmeleon.plugins.bookmarks.editdialog.left", -1082069294);
user_pref("kmeleon.plugins.bookmarks.editdialog.top", -53159788);
user_pref("kmeleon.plugins.bookmarks.editdialog.width", 1083309314);
user_pref("kmeleon.plugins.bookmarks.load", true);
user_pref("kmeleon.plugins.bookmarks.toolbarFolder", "Personal Toolbar Folder");
user_pref("kmeleon.toolband.Bookmarks.break", 0);
user_pref("kmeleon.toolband.Bookmarks.index", 1);
user_pref("kmeleon.toolband.Bookmarks.size", 210);
user_pref("kmeleon.toolband.Bookmarks.visibility", true);
Also, there is a file
prefs-1.js, looks like some old version of original. Maybe I done it someday and forgot. In any case it doesn't affect the situation.
This is old problem, but i always hope that some new versions of k-meleon get rid of this disease and it's always not. Heh.
Please, help.
Sincerely yours,
Andrey Kuzmich
