 Since Torbrowser 3.X comes with TorLauncher I really like the
 TorBrowserBundle and use it daily as my Firefox replacement.

 Although the browser experience and speed is really good I noticed an
 issue that hampers the usability and leads to the impression that TBB is
 slow.

 When I open the main menu or context menu or when I switch in the main
 menu from the open "File" menu to "Edit" this is much slower in TBB than
 in the standard FF.

 Examples:

 1.) right click in the URL address field. TBB is much slower than FF
 2.) open "File" menu and move the mouse pointer over "Edit". There is a
 significant delay in TBB compared to FF.
 3.) I have the bookmarks toolbar visible and there are folder in it. When
 I click on a folder in TBB it can take up to 1-2 second until it opens. In
 FF the bookmark toolbar folder open immediately.
 4.) Right click in the browser window to get the standard browser context
 menu. It take significantly longer in TBB than in FF
 5.) I have structured my bookmarks with folders. If I click on Bookmarks
 in the main menu and move the mouse down from folder to folder the folder
 submenu opens immediately in FF whereas there is a delay in TBB.

 The delay I am talking about is not always the same. Sometimes it open
 almost immediately (but never as fast as in FF) sometimes the delay is
 significant up to 1-3 seconds.

 From a user perspective TBB handling seems to be slower because of that.
 When opening a menu I sometime have the impression as if TBB loads the
 menu over the network.

 The fact that TBB loads pages over the Tor networks slower than FF is
 understandable from a user perspective. But that local actions are slower
 than in FF is something a user cannot understand.

 Is there something I configure in TBB to make menu handling faster?

 I am using TBB 3.5 I have build via gitian on Linux 64-bit Ubuntu.

 Thanks & regards,

 torland
