Hi! I sometimes play 2 YouTube videos each in own browser. In FireFox it pauses the video in the browser not active. Is there a setting to keep both videos playing?

Hello all,

I am looking for a way to lock align a zoomed in site (when horizontal scroll bar is visible) to the right instead of default alignment to the left when I open next page.

I have previously been able to include the tab 'Close Tab' item in the #contentAreaContextMenu by adding it to browser.xhtml. This no longer works even though 'Reopen Closed Tab' and 'New Tab' still do.

     <menuitem id="toolbar-context-openANewTab"
               command="cmd_newNavigatorTab"
               data-l10n-id="toolbar-context-menu-new-tab"/>
     <menuitem id="context_closeTab"
               label="Close Tab"
               data-lazy-l10n-id="tab-context-close-n-tabs"
               data-l10n-args='{"tabCount": 1}'/>
     <menuitem id="context_undoCloseTab"
               label="Reopen Closed Tab"
               data-l10n-id="tab-context-reopen-closed-tabs"
               data-l10n-args='{"tabCount": 1}'
               observes="History:UndoCloseTab"/>

I was previously using the following which no longer works either.

     <menuitem id="context_closeTab"
               label="Close Tab"
               oncommand="BrowserCloseTabOrWindow(event);"/>
