VScroll Bar and the issue of the tree
I have a component of the tree and use a DataDescriptor custom, when I dynamically add data to the DataProvider, I have a set that does not show in the tree. When these items added, indicates VScrollBar. But as the elements are 'hidden' and do not appear in the tree, VScrollBar should not be displayed. If I develop an element in the tree, then VScrollBar will disappear and the tree will look like is it supposed to be.I tried to use (individually and in combination) invalidateSize(), invalidateDisplayList() and invalidateProperties() invalidateList() on the tree, but it isn't updated VScrollBar as it should.
Any help would be greatly appreciated, thank you.

In fact I found a solution to my problem and why it is showing the VScroll bar.
In the DataDescriptor when my hidden objects are to be added to the collection, I am sending an event on the model (the event is the event to the collection of its kind add) and when the collection got this event it would update is the 'size' and then the tree thinks that his screen is larger than it really was and so VScroll bar. So I removed my expedition event if the collection would not last updated its "size".
This fixed my problem, and I hope that this helps out you some Arun.

How can I combine the navigation bar and the menu bar on the same line to save space?
V29 Firefox seems to be a huge not backward in customization. I need to save room for the content so already I disabled the tabs and combined in the menu bar and the navigation bar on the same line. The url space is too long anyway. Now with v29 all my customization is gone and I can't get it back. I can move me is more points on the navigation bar to combine it with the menu bar. Why this was done? It limits only my ability to customize my browser? I'm very frustrated that you had a great browser and ruined.
You should see Classic theme restaurateur, it contains many parameters. This module applies to customize Firefox 29. https://addons.Mozilla.org/en-us/Firefox/addon/classicthemerestorer/

I found a few larger images (986 x 1024 and 2420 x 2514) I'd like to see on the entire screen. Is there a way to do this by enabling / disabling (then restore it later) of all toolbars - including the status bar and the task bar? Or is there an FF extension that will make perhaps even easier?
Press F11 or select "full screen" in the menu. (If there is still floating toolbars around after that, do a right-click on the toolbar and remove the checkbox.)

How can I move buttons between the address bar and the search bar?
I use for home, Developer Web, Download and so forth, to the right of the address bar, between that and the Google bar.
But now I can't move in there, with the latest version of Firefox.
I wish that when they create a new version, they would not take away what we customize things to do. so I can get all of them back?

- The dashed border points out that you can drag and drop things here. White tile on the new tab Page have a similar design.
- The search bar can be moved.
- The address bar is pinned in place, unless you install Classic theme restaurateur.

I recently hooked another monitor to my laptop, that was when the problem occurred, but even after restarting Firefox * and * my computer, it did not always work. By collapse, I mean when you press F11, the open tabs and the address bar appear smaller, and then they slide up until what you don't see it (unless you mouse over). Please help me solve this =)
Thank you!
You can right click on the tab bar or the Navigation bar mode full screen (F11) and make sure that "Hide toolbar" is enabled.
Start Firefox in Safe Mode to check if one of the extensions (Firefox/tools > Modules > Extensions) or if hardware acceleration is the cause of the problem (switch to the DEFAULT theme: Firefox/tools > Modules > appearance).
- Do NOT click on the reset button on the start safe mode window or make changes.

If you right click on the bar at the top of the page in the browser, you can check and uncheck what bars appear. I accidentally disabled something there and now when I click I can't get any menu to double-check my menu on the right, State bars so that they are visible. Currently they are not visible, I have no way to move or change settings.
OK, got it fixed, I kept fishing around this site and found an answer. Press the Alt key and the menu bar appear temporarily, long enough to restore the bar to be visible.

Address bar and the search bar locked on Windows Explorer (not Internet Explorer)
My address bar is tiny (20%) percent of the width of the window and the search box is about 80%.
I want to make the address bar wider than the search box.
The toolbars are not locked.
When I place the mouse pointer on the gap between the address bar and in the search box, I get the <->icon, but I'm not able to slide left to right.
I tried to change the DPI (I don't think that IPR has nothing to do with it)
