1 2 18 Google has begun rolling out vertical tabs and an updated full-page Reading Mode in Chrome browser version 146, making both features available without requiring experimental flags. ** 1 5 The long-awaited update marks Chrome’s entry into a feature space dominated by competitors like Microsoft Edge and Firefox, which have offered vertical tabs for years.** 1 2 18 Vertical tabs move the traditional horizontal tab strip from the top of the browser window to a collapsible sidebar on the left side. 1 2 5 This new layout displays full page titles even when users have dozens of tabs open, solving a common frustration for multitaskers who previously struggled with compressed tab labels and identical favicons.
How to Enable Chrome’s New Vertical Tabs
1 2 3 Enabling vertical tabs requires just a simple right-click on any Chrome window and selecting “Show Tabs Vertically” from the menu. 1 3 To return to the traditional horizontal layout, users can right-click inside the vertical tab panel and choose “Show tabs at the top.” 11 For users still on Chrome 145 or those not seeing the feature immediately, the vertical tabs functionality remains accessible through Chrome’s experimental flags system at chrome://flags/#vertical-tabs. 11 After enabling the flag and relaunching Chrome, users must navigate to Settings > Appearance and change the Tab strip position to “Left.”
Key benefits of vertical tabs:
- 1 Tab Groups are easier to organize in the vertical layout
- 1 The sidebar can minimize to show only favicons, saving screen space
- 25 Tab search and grouping functionality remains preserved from the horizontal layout
- 11 Native implementation offers zero performance overhead compared to extensions
13 The vertical arrangement provides significantly more room for tab management, making titles readable and groups sensible. 13 This change particularly benefits users who regularly work with 15 to 30 tabs open simultaneously.

Chrome’s Reading Mode Gets Major Upgrade
1 3 4 18 The browser’s Reading Mode has evolved from its previous side-panel design to a full-page interface that fills the entire window. 2 3 4 Users can activate this immersive experience by right-clicking on any webpage and selecting “Open in reading mode,” which removes all visual distractions including ads, videos, and complex layouts to create a text-focused reading environment. 1 20 The updated Reading Mode includes text-to-speech capabilities and customization options for fonts and background colors. 19 22 Available font choices include Sans Serif, Serif, Mono, and the newly added Lexend option, while background colors can be set to Light, Sepia, or Dark with text size adjustable up to 250%. 19 22 Google previously updated Chrome’s Android Reading Mode in February 2026, moving the activation button to a consistent location in the three-dot overflow menu where it appears regardless of the page being visited. 19 22 The browser now preserves Reading Mode preferences across different pages, ensuring a consistent experience.
Gradual Rollout Across Chrome 146
1 18 Both features are being distributed gradually through Chrome version 146, though Google has not provided a specific timeline for complete rollout. 1 18 Users can verify their Chrome version and check for updates by clicking the three-dot menu, selecting Help, and then About Google Chrome. 21 25 The vertical tabs feature first appeared in Chrome’s experimental Canary build before moving to public beta in January 2026, with Chrome 146 shipping the feature on March 12. 25 Chrome 145 Beta became available globally on January 19, 2026, marking the first public access to vertical tabs through feature flags.
User Reception and Industry Impact
24 Early user feedback reveals divided opinions, with some viewing vertical tabs as essential for document-heavy workflows while others remain committed to traditional horizontal tabs. 26 Writers and researchers particularly value the feature, noting that easily sifting through tabs of information and data is vital to streamlining their work. 3 Some users expressed surprise at Google’s decision to implement a full-page reading mode, given potential conflicts with the company’s advertising business model. 5 21 The timing appears significant as news websites have become increasingly cluttered with ads and subscription prompts, partly driven by declining referral traffic from Google itself as AI tools answer more queries directly.
Browser feature comparison:
| Browser | Vertical Tabs | Full Reading Mode |
|---|---|---|
| Chrome | 1Now available (2026) | 3Full-page (2026) |
| Edge | 24Since 2021 | Available |
| Firefox | 24Since 2025 | Available |
| Safari | 25Tab overview only | Full-page |
5 Chrome’s adoption of these features reflects growing competition from modern browsers and AI-focused alternatives, which have pushed Google to accelerate its development cycle. 5 Recent months have seen Chrome introduce Gemini AI integration, autofill improvements, Split View mode, and announce a faster release schedule.
What This Means for Chrome Users
25 The extensive development process throughout 2025 and early 2026 suggests Google prioritized stability over rushing to market. 11 13 For users with 20 or fewer tabs in a single project, Chrome’s native implementation provides a cleaner sidebar without extensions, though power users managing multiple projects may still require additional tools. 11 The native vertical tabs solve the visual layout problem but don’t address workflow challenges like switching between multiple project contexts or recovering from accidental tab closures. 25 However, the feature works immediately after activation across all supported desktop platforms. 11 While Google hasn’t announced when vertical tabs will be enabled by default, the Chrome community expects mid-2026 (versions 148-150) based on typical flag lifecycles. 11 Users who enable the flag now won’t need to re-enable it after Chrome updates.
The rollout of vertical tabs and enhanced Reading Mode represents Chrome’s most significant interface update in years. 13This shift acknowledges that browsing habits have fundamentally changed, with users demanding better tools for managing information overload. As these features reach Chrome’s massive user base, they’re likely to reshape how millions interact with their browser daily, finally bringing parity with competitors who recognized these needs years earlier.
