Remove a tab in a TabNavigator if there isn't a html file

I created a component that contains a TabNavigator. This component will open in a TitleWindow when a user clicks on an item in a list (list of survey points). There are two possible tabs in the TabNavigator: the first tab contains a text control and the second contains a control VideoDisplay (playing a flv that exists on a server). The text tab displays always, but the point does not have an flv file that is associated with. I don't want the second tab to see if the flv file does not exist on the server. Here are most of the code (leaving a portion of the variable and functions):

Currently, the task pane opens with the visible video tab for each of the points. But when I click on the video tab itself, if the flv file does not exist, the tab will disappear. How this code so that the tab will not be displayed when the component opens? FinishInitialize code does not remove the tab as I thought it would be.

Try to set the creationPolicy to all

    Any chance that you define the many tabs as your 'home page' opens automatically when you start Firefox?

    Reduce the tabs in closing those that you do not want, then click on Tools / Options / general and click the use current Pages button.

    Next time you open, you will see only those active tabs.

  • How to resize tabs, Bar Menu and Bookmarks Bar 36.0, no help file 'userChrome.css '?

    So, I lost my profile when updated FF and had to create a new. From what I can tell, to do what I want to do I need a Chrome folder inside the profile folder. There isn't, so I created one. I also have a .css file named exactly how I put it in the title, this is the correct name, or 'user' is my profile name?

    Last but not least, here is the exact text I have in the file, nothing more, or less, just that:

    @namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); /* only needed once */
#TabsToolbar { height: 15px !important; }
#PersonalToolbar {height: 4px !important;}
#BookmarksToolbar {height: 4px !important;}
#MenuToolbar {height: 4px !important;}
#tabbrowser-tabs { height: 15px !important; }
#TabsToolbar { margin-top:-15px!important; }

    Saved the file. Restarted FF, no effect. Numbers changed, still no effect.

    TIA for help.

    PS there is probably some redundancy for sure, please advise. I want all 3 in the smaller thread title (as in the least height)

    You can use negative margins to extend these bar to fill the height of the Navigation bar.

    #urlbar-container,#search-container {margin-top:-1px!important; margin-bottom:0xp!important}

    The large back button adds more at the height of the Navigation toolbar and you need to adjust the padding of his image to reduce its height.

    #urlbar-container #back-button {margin-top:1px!important; margin-bottom:0px!important}
#urlbar-container #back-button image {padding:3px 3px !important}
