#personal-toolbar {display: none;}
#browser-toolbox:hover > #personal-toolbar {display: -moz-box;}

but why it does not work with livebookmark?
when i click the title(livebookmark), it does nothing.

please help, thank you.

And - it’s a shame that a change like this is introduced after the extension developers have been encouraged to update their extensions. Not to mention that resetting all toolbars to their defaults might put off a few users (and confuse many others who will try to find the extension icons they never had to add manually before).

Couldn’t that be done from within the code called on upgrade (whatever triggers the compatibility checking and the display of the whatsnew page)?

Snarky Note:
Off the top of my head:

// get the rdf service
var rdfSvc = Cc[”@mozilla.org/rdf/rdf-service;1″].getService(Ci.nsIRDFService);
// get the localstore datasource
var localstore = rdfSvc.GetDataSource(’rdf:local-store’);
// get an nsIRDFResource for the navigator-toolbox item
var navigator_toolbox = rdfSvc.GetResource(’chrome://browser/content/browser.xul#navigator-toolbox’);
// enumerate its properties
var properties = localstore.ArLabelsOut(navigator_toolbox);
while(properties.hasMoreElements()) {
var property = arc_labels.getNext();
// enumerate the values for this property
var targets = localstore.GetTargets(navigator_toolbox, property, true);
while(targets.hasMoreElements()) {
// clear the value
localstore.Unassert(localstore, arc_label, targets.getNext());
}
}

now, that wasn’t too hard was it?

I’ve had enough of the irrational rdfoibia.
