Features & Capabilities

Alternative to Arc's Sidebar/Edge's Vertical Tabs.

It allows you to have more control over your web browsing experience by effectively managing multiple tabs at once.

🚀 How do vertical tabs work?

Enabling the vertical tabs setting moves your open tabs from the top of your browser window (above the address bar) to the left side of the window. This allows the tabs to be displayed vertically, stacked one on top of the other, instead of horizontally.

✨ Features

⚡️ Manage tabs and tab groups efficiently with a vertical tabs panel.
🗂️ You can now save, restore, and reorder tabs, including tab groups, using drag-and-drop functionality.
🔄 The Vertical Tabs Panel presents your open tabs in a side-by-side layout.
🔍 Efficiently search multiple tabs using fuzzy search.
🧹 To save memory, you can suspend open tabs.
☁️ Enable cross-browser cloud synchronization with a single login.
🌛 Dark Mode Support.
💾 Space Backup Solution
📑 Save your session as a JSON file
☁️ Cloud sync by login
✨ AI-powered Tab Grouping
🔗 Group Guardian, Auto Grouping your tabs within URL matchers

👍 The advantages of vertical tabs

Vertical tabs are an effective solution for avoiding clutter in your browser window and maximizing your on-screen space. Additionally, they enhance tab visibility for easier identification.

PS: Side Space is a futuristic vertical tab manager that can only be used with Firefox version 139 or above.

User Reviews

I LOVE this software. Problem is, It's not Developed for Firefox. AT ALL. Most features DO NOT EXIST for Firefox users. I can't even sign in to my Side Copilot account through the addon. There are SO MANY *COOL* features in Copilot, AND I WANT TO USE THEM, But they don't exist in this browser. > Hell, It's so cool I might dust off my old Chromium version just to try it out and [sarcasm coming] SEE WHAT I'M MISSING! Please, Side Space, develop your app further for Firefox, you could get a lot of attention, you'd even find good competition as the market for sidebar apps is growing, all the time a new one hits the Addons Market. > You won't be disappointed by the VAST community of users here.
