What is Sidebar Tabs?

'Sidebar Tabs' is a ground-breaking Firefox add-on that reimagines tab management for increased productivity. This unique add-on shows tabs vertically in the sidebar, emulating leading-edge tab interaction. It further enhances browsing by providing a feature to group tabs, with each group being color-coded. These grouped tabs are collapsible for clean navigation. The ability to expand or collapse a group of tabs with a simple click or through a context menu adds to the user-friendly nature of this add-on. 'Sidebar Tabs' proves to be an essential tool to optimize browsing, especially when handling multiple tabs.
