We’ve reported Mozilla is working on multiple tab selection or multiselect tabs feature for Firefox browser, the feature has improved a lot since then and now available for testing in Firefox 63 beta and is likely to ship with Firefox 64.
Multiselect Tabs feature in Firefox
In latest Firefox beta, the multiselect tabs feature is enabled by default and can be disabled by toggling browser.tabs.multiselect preference value.
To get started, ensure you’re using latest beta or Nightly.
You can able to select a range of tabs by using the Shift key on Windows.
You can select multiple tabs by using Ctrl Key on Windows or Cmd on Mac.
So Shift key is the super hotkey you can use on Windows and Firefox gives higher precedence to that key over Ctrl when both are pressed at same time to select a tab.
Here is how you can multi-select tabs with Shift key
1. Select first tab with mouse left click
2. Hold the Shift button and select the last tab in the range, a blue line appears above selected tabs to indicate the user that tabs are selected.
Now you can right click and do operations on tabs by selecting an option such as reload selected tabs, Mute, Pin selected tabs, Move to a new window, Send tabs to device, Reload selected tabs, Bookmark the tabs and Close Selected tabs.
Important note: User can use Ctrl/ Cmd key (but not Shift key) to remove a tab from tabs in multiselection.
We’ve recently covered Firefox 64 allows to drag and drop a selection of tabs to bookmarks bar to bookmark, that has been built on top of multiselect tabs feature.
Do note at the time of writing, the feature is still not complete and some work still needs to be finished by Mozilla regarding accessibility and bookmarking and Send to Device.
