Users had voted to request Vertical Tabs for Firefox at the Mozilla Crowdicity community. The feedback portal, which was
slow to pick up the pace, is abuzz with activity. A Product Community Manager at Mozilla, has finally responded to the
request with good news. He wrote that since the request has emerged as a top idea in the community, it has been reviewed by the developers at Mozilla. They are looking at ways to improve the tab management, and are researching the possibility of adding support for Vertical Tabs in Firefox. This of course does not mean that the feature is certain to be added, which is why I wrote "could" instead of "will".
