Multiple Tab Handler Ver.3.1.12 for Mozilla Firefox

Note: This page is archived and maintained mainly as a histrical document. Please see the Mozilla Add-ons page and the GitHub repository for latest information.

IMPORTANT SECURITY NOTE: All versions MTH 2.x and MTH 3.x older than MTH 3.0.7 had a data disclosure problem via API for other addons. Sensitive tab information including private window tabs were unintentionally exposed to untrusted addons, regardless they were not have permissions to access those information via WebExtensions API. I strongly recommend you to update to MTH 3.0.7 and later. Please see detailed information also.

What's this? ...abstract

This provides features to handle multiple tabs at once, for example, close them, reload them, and so on. When you press the mouse button and drag in the popup panel, they are selected. After you release the button, the popup to choose command will be shown. Of course, you can toggle selection by Ctrl-click on each tab and call features from the context menu. Yes, the behavior looks like Excel. And you can also close multiple tabs directly by dragging on closeboxes.

By the way, this includes "Copy URL" and "Save Tab to File" features.

Moreover, this addon is designed to work with Tree Style Tab. If you install both addons, you can select tabs in the sidebar by dragging . (Note that you need to long-press on a tab to start selection. Otherwise - if you start dragging immediately, it just moves the tab.)

This is developed under a project to restructure TBE for Firefox 2.

Receiving drag and drop of multiple tabs

Multiple Tab Handler supports drag and drop of multiple tabs. You can receive all of dropped tabs by MTH's API like following samples.

On 0.6 or later, you can get dragged tabs via the data transfer object of HTML5 Drag and Drop events.In this case the first data (index == 0) is not leftmost tab but the tab you start the dragging.


onDrop : function(aEvent) {
  var tabs = [];
  var dt = aEvent.dataTransfer;
  for (let i = 0, maxi = dt.mozItemCount; i < maxi; i++) {
    tabs.push(dt.mozGetDataAt(TAB_DROP_TYPE, i));
  }
  tabs.sort(function(aA, aB) { return aA._tPos - aB._tPos; });
  ...
},

You can get just same result by the utility method MultipleTabService.getSelectedTabs(), if you give the drop event to the method.


onDrop : function(aEvent) {
  var tabs = MultipleTabService.getSelectedTabs(aEvent);
},

Moreover, old API compatible to 0.5 or older is available too.

MultipleTabService.getBundledTabsOf() method returns an array of selected (drag-and-dropped) tabs if you hand one of them to him. If there is no selection or you hand any object not a tab, he returns a blank array. For example, this shows an URI list of dropped tabs:


onDrop : function(aEvent, aData, aSession) {
  var tab = aSession.sourceNode;
  if ('MultipleTabService' in window) {
    var tabs = MultipleTabService.getBundledTabsOf(tab);
    if (tabs.length) {
      // When multiple tabs are dropped,
      // show URIs of all tabs.
      alert(
        tabs.map(function(aTab) {
          return aTab.linkedBrowser.currentURI.spec;
        }).join('\n')
      );
      return;
    }
  }
  // Normal operation
  alert(tab.linkedBrowser.currentURI.spec);
},

If you hand an object to MultipleTabService.getBundledTabsOf() method as the second argument, you can get the <tabbrowser/> element which is the owner of dragged tabs, and the owner window (DOMWindow) of the <tabbrowser/>. For example, this codes removes original dragged tabs if they are dropped to another window:


onDrop : function(aEvent, aData, aSession) {
  var tab = aSession.sourceNode;
  if ('MultipleTabService' in window) {
    var info = {};
    var tabs = MultipleTabService.getBundledTabsOf(tab, info);
    if (tabs.length) {
      var uris = tabs.map(function(aTab) {
            return aTab.linkedBrowser.currentURI.spec;
          }).join('\n');
      if (info.sourceWindow != window)
        tabs.forEach(function(aTab) {
          info.sourceBrowser.removeTab(aTab);
        });
      }
      ...
      return;
    }
  }
  ...
},

How to cancel drag and drop of multiple tabs?

When you select multiple tabs and start to drag one of them, then Multiple Tab Handler detects the operation and process your action as "drag and drop of multiple tabs". If you want to cancel this behavior and you want to define custom operations for dragging of multiple tabs, you have to cancel a custom event "MultipleTabHandler:TabsDragStart" which is fired by Multiple Tab Handler.


var listener = function function(aEvent) {
     switch (aEvent.type) {
       case "MultipleTabHandler:TabsDragStart":
         return aEvent.preventDefault();
   
       case "dragstart":
         // custom operations to start dragging of multiple tabs
         return;
     }
   };

gBrowser.mTabContainer.addEventListener(
  "MultipleTabHandler:TabsDragStart", listener, false);
/* To handle dragstart events before Firefox's default handler
   cancels it, you have to register the listener for the
   capturing phase. */
gBrowser.mTabContainer.addEventListener(
  "dragstart", listener, true);

Adding new menuitem to the popup menu for tab selection

Overlaying to chrome://multipletab/content/multipletab.xul or chrome://browser/content/browser.xul can insert new menu items to the popup menu.

This is a simple example:


<menupopup id="multipletab-selection-menu">
  <menuitem id="selection-feature1"
    insertbefore="multipletab-selection-remove-separator"
    label="Feature 1"
    oncommand="Feature1(MultipleTabService.getSelectedTabs());"/>
</menupopup>

Adding new menuitem to the context menu on tabs

Overlaying to chrome://multipletab/content/multipletab.xul or chrome://browser/content/browser.xul can do it.

This is a simple example:


<menupopup id="multipletab-tabcontext-menu-template">
  <menuitem id="context-item-feature2"
    label="Feature 2"
    oncommand="Feature2(this.parentNode.parentNode.parentNode.parentNode.selectedTab);"/>
</menupopup>

To indicate the position of the item to be inserted at, use multipletab-insertbefore (or multipletab-insertafter) attribute. The item will be inserted before (or after) the node which is the result of its value evaluated as JavaScript expression. A reference to the popup element, tabContextMenu is available. Following is the example to insert item to the third position from the last.


  <menuitem id="context-item-feature3"
    label="Feature 3"
    multipletab-insertbefore="tabContextMenu.lastChild.previousSibling"/>

Moreover, you can write XPath expression as value of those attributes. To do it, put a prefix "xpath:" before the expression. When the expression is evaluated, the context node will be tabContextMenu, and the first node of the results will be gotten. For example:


  <menuitem id="context-item-feature3"
    label="Feature 3"
    multipletab-insertbefore="xpath: child::*[last()-1]"/>
  • The menuitems are inserted to the popup at the startup of browsers. If some extension modifies the popup, the result may be changed from your expecting.
  • The menuitems which is really inserted to the DOM tree has a new id from its template. It will be <Original id>-tabbrowser012345. If you control the style of inserted items, you should use class-selector instead of id-selector and so on.

Menu labels for vertical tab bar

You can specify special labels for each menuitems.

If the tabs are shown horizontally (normal), the value of label-horizontal attribute will be shown as its label. If the tab becomes vertically, the value of label-vertical attribute will be used.


  <menuitem id="context-item-feature4"
    label-horizontal="Feature 4, do it for Left Tabs"
    label-vertical="Feature 4, do it for Upper Tabs"/>

How to show/hide/enable/disable extra menuitems?

Setting a new boolean value extensions.multipletab.show.<the id of the menuitem inserted to those popups> controls the appearance of the item.

This extension doesn't include an UI to customize extra menu items inserted by other extensions. If you want to control it in GUI, use an overlay to the resource chrome://multipletab/content/config.xul.

Moreover, you can also control visibility or accessibility of the menuitems dynamically, by their multipletab-available attribute or multipletab-enabled attribute. Values of those attributes are evaluated as JavaScript expressions. The menuitem becomes shown if the value of multipletab-available attribute equals true, otherwise it becomes hidden. The menuitem becomes enabled if multipletab-enabled equals true, otherwise disabled.


  <menuitem id="context-item-myservice-feature"
    label="A feature for 3 or more selected tabs"
    multipletab-available="MyService.available()"
    multipletab-enabled="selectedTabs.length &gt; 3"/>

The menuitem in the sample above will be shown when the returned value of MyService.available() equals true, and it will be enabled when three or more tabs are selected. You can use following variables in expressions:

tabbrowser
The DOM node of tabbrowser element. Same to gBrowser.
tabs
An array of all tabs in the tabbrowser. Same to Array.slice(gBrowser.mTabContainer.childNodes).
selectedTabs
An array of selected tabs in the tabbrowser. Same to MultipleTabService.getSelectedTabs(gBrowser).

Visibility of menuitems is controlled by both extensions.multipletab.show.id (default=true) and multipletab-available (default=true). The menuitem will be shown when both equal true. In other words, the item will be hidden when one or all of them equals false.
