Chrome Browser with Vertical Tabs

Chrome安定版にネイティブ縦タブが登場。数秒でサイドレールに切り替え、レイアウトだけで十分か判断しましょう。

Chromeで縦タブを有効化

2026年4月の安定版パスから始めてください。

Stable Chrome (recommended)

Right-click
  1. Update Chrome to the latest stable release (April 2026 or newer).
  2. Right-click any Chrome window title bar or tab strip.
  3. Choose Show Tabs Vertically—the list moves to the left sidebar.
  4. Drag the sidebar edge to resize; collapse when you need more canvas.

This is the path Google documents on its Chrome blog for mainstream users.

chrome://flags fallback

Early access
  1. Open chrome://flags in the address bar.
  2. Search for Vertical Tabs and set it to Enabled.
  3. Relaunch Chrome when prompted.
  4. If the right-click menu still lacks the option, your channel may not have rolled out yet—retry after the next update.

Useful on Beta/Dev channels or if stable rollout is staged in your region.

Extension stopgap

Legacy
  1. Install a reputable Vertical Tabs extension from the Chrome Web Store.
  2. Pin the extension and grant tab permissions.
  3. Disable the extension once native vertical tabs appear—two sidebars will fight for space.

Only if native vertical tabs are unavailable on your Chrome version today.

Chrome縦タブのできること・できないこと

Chrome’s side rail solves title truncation and basic grouping. It does not turn your browser into a research workstation.

Chromeが得意

  • Full tab titles on a vertical list instead of a cramped top strip
  • Tab groups aligned with Google’s productivity updates
  • Familiar Chrome extensions and sync after you flip the layout
  • Collapsible sidebar on smaller laptop screens

まだ手動

  • Auto-cluster dozens of research tabs by topic without extensions
  • @-reference open tabs as AI context in one omnibox
  • Run Agent tasks in isolated tab groups while you keep browsing
  • Full-text archive of saved pages when sites go offline

Chromeで十分ですか？

Vertical tabs fix visibility—not execution. Pick the scenario that sounds like your week.

実用的な結論

Chrome’s native vertical tabs are likely sufficient. Enable Show Tabs Vertically and give yourself a week to rebuild muscle memory.

Chrome vs Tabbit 比較

Chromeのサイドレールでは足りないとき

Tabbit keeps the vertical-tab mental model you wanted from Chrome—then adds Agent research, Skills shortcuts, and knowledge-base bookmarks so the layout change actually saves hours.

Vertical sidebar + smart groups

See full titles on a side rail. Tabbit clusters tabs by project so a 40-tab research sprint stays scannable without constant dragging.

Omnibox with @-context

Type @ to pull in open tabs, tab groups, screenshots, or local PDFs. No more copying URLs between ChatGPT and Chrome.

Agent mode on parallel rails

Delegate multi-site research to Agent runs in their own tab group while you keep reading in the main window—true side-by-side work.

Chrome縦タブ FAQ

Does Chrome have vertical tabs in 2026?
Yes. Google added native vertical tabs to stable Chrome in April 2026. Right-click any Chrome window and choose Show Tabs Vertically to move tabs to a left sidebar.
Is there a way to have vertical tabs in Chrome without flags?
On current stable builds, the right-click Show Tabs Vertically menu is the supported path—no flags required. If you do not see it, update Chrome or use the chrome://flags Vertical Tabs toggle until rollout reaches your channel.
How do I change the position of tabs in Chrome?
Vertical tabs open on the left by default in Google’s 2026 release. Resize by dragging the sidebar edge; collapse the rail when you need a wider page. Horizontal tabs return when you disable Show Tabs Vertically.
Which browsers have vertical tabs besides Chrome?
Microsoft Edge, Vivaldi, Arc, and Tabbit all ship vertical or sidebar tab layouts. See our vertical browser tabs guide for a full comparison.
Do Chrome vertical tabs work with extensions?
Most extensions still run, but a second vertical-tabs extension will conflict with Chrome’s native rail. Remove legacy extensions after enabling the built-in sidebar.
Can Chrome vertical tabs help with research?
They improve title readability and group management, but Chrome will not summarize, cite, or execute multi-step research for you. Tabbit adds Agent mode and @-context for that workflow.
Is Tabbit a Chrome replacement?
Tabbit is a standalone AI-native browser with one-click Chrome import—bookmarks, passwords, history, and extensions. You keep vertical tabs and gain Agent execution without staying inside Chrome.
Is Tabbit free on Windows and Mac?
Yes. Tabbit is free on macOS and Windows with vertical sidebar, Agent mode, and top-model access—no invite code required.
