''Is there a short/hotkey to show/hide bookmark toolbar?'' There is no keyboard shortcut for the bookmarks toolbar. "Alt" will display the Menu Bar "Ctrl+/" toggles the add-on bar "Ctrl+K" displays Search bar because that is its entry area. "Ctrl+L" displays Location bar because that is its entry area. But there are alternatives, and you could set up zombie mode with the "Auto Hide" extension, so that the that is the only toolbar hidden or not hidden, though I wouldn't do that. You can use F11 to toggle Full Screen mode, which hides title bar and toolbars. On Windows you can use '''AutoHide -- http://www.krickelkrackel.de/autohide''' which provides a Full Window mode("zombie mode") with "Shift+F11" similar to full screen but within the confines of the window that allows you to just show the title bar, with options I use with it always show the tabs bar and addons bar in Full Screen or Full Window mode. In Full Screen or Full Window mode you can move the cursor to the top and see toolbars, use F10 or Alt to see menu bar, use Ctrl+K to see search bar, use Ctrl+L to see Location Bar. To see bookmarks bar you would need to show all toolbar toggle F10 or toggle F11. My bookmarks toolbar takes very little space less vertical space than shown in this [http://dmcritchie.mvps.org/icons/fx4toolbars.png before/after] picture, see items 61-66 on styling in the following: You can make '''Firefox 6.0''' look like Firefox 3.6.*, see numbered '''items 1-10''' in the following topic [http://dmcritchie.mvps.org/firefox/firefox-problems.htm#fx4interface Fix Firefox 4.0 toolbar user interface, problems (Make Firefox 4.0 thru 6.0, look like 3.6)]. ''Whether or not you make changes, you should be aware of what has changed and what you have to do to use changed or missing features.'' * http://dmcritchie.mvps.org/firefox/firefox-problems.htm#fx4interface There is a lot more beyond those first 10 steps listed, if you want to make Firefox more functional. <br><small>Please mark "Solved" one answer that will best help others with a similar problem -- hope this was it.</small>
