After years of user demands and competitor one-upmanship, Google has slipped native vertical tabs into the latest Chrome Canary builds, marking a pivotal shift in the browser’s user interface. Long a staple in rivals like Microsoft Edge and Vivaldi, this feature promises to alleviate the tab overcrowding that plagues power users juggling dozens of sites daily. Chrome Unboxed first detailed the rollout on November 20, 2025, noting that enthusiasts can enable it immediately in the experimental channel.

The arrival stems from recent Chromium Gerrit commits, accelerating since September 2025, as reported by Chrome Unboxed. Previously, Chrome loyalists relied on extensions or side-panel workarounds, but Google’s native implementation integrates seamlessly with tab groups and search, potentially boosting productivity in enterprise environments.

Industry observers see this as Google responding to market pressures. With Edge capturing market share through vertical tabs since 2020 and Vivaldi catering to customization aficionados, Chrome’s 65% desktop dominance faced erosion among multitaskers, according to StatCounter data.

Enabling the Feature: A Canary Deep Dive

To access vertical tabs, users must download Chrome Canary—the bleeding-edge build—and navigate to chrome://flags. Search for “side-panel-vertical-tabs” or related flags, enabling them before relaunching. Alternatively, right-click any tab and select “Show tabs on side,” as highlighted in Chrome Unboxed‘s hands-on guide from November 20. Early testers report a sidebar layout with tab previews, search, and group support, though it’s rough around the edges.

ZDNET on July 22, 2025, flagged the initial discovery in Chromium source, praising its potential to mimic Edge’s polished sidebar. Digital Trends, in a November 20 article, emphasized relief from “tiny Chrome tabs,” quoting user frustrations over horizontal clutter.

Historical Context: Years of Pent-Up Demand

The push for vertical tabs dates back to 2023 community threads on Google’s Chrome support forums, where power users clamored for parity with Edge and Vivaldi. A Google Chrome Community post from April 2023 captured the sentiment: “When is Chrome bringing vertical tabs like Edge and Vivaldi out of the box for power users?” Reddit’s r/browsers subreddit echoed this in July 2025, with a post titled “Finally! Chrome is getting vertical tabs – why I’m a huge fan, and where you can try them now.”

Chrome Unboxed tracked commits surging in September 2025, signaling Google’s seriousness. Posts on X from Chrome Unboxed on November 20 amplified the news: “Finally! Google Chrome is getting native vertical tabs in the latest Canary build. Here is how to enable them.”

This isn’t isolated; related experiments like Chrome’s split tabs, tested in September 2025 per Tom’s Guide, underscore UI modernization efforts amid Android integration rumors.

Technical Underpinnings and Early Impressions

Under the hood, the feature leverages Chromium’s side panel architecture, allowing dynamic toggling without extensions. Phandroid reported on November 20: “Chrome vertical tabs feature enters testing in Canary build. Google finally catches up to Edge and Firefox with sidebar tab management.” Dataconomy added: “Google has introduced vertical tabs in the latest Canary build of Chrome for desktop, enabling users to switch layouts via right-click menus.”

Early adopters on X praise the integration. Windows Report’s November 13 piece, “First Look: We Tried Chrome’s Hidden ‘Vertical Tabs’ Feature,” described: “Hands-on with Chrome’s hidden Vertical Tabs feature in Canary. A new ‘Show tabs on side’ option reveals an early layout with Tab Search and tab groups.” Feedback highlights smoother workflows, though some note missing animations and persistence issues.

Competitive Landscape and Rollout Prospects

In the browser wars, vertical tabs bolster Chrome against Edge’s enterprise gains and Brave’s sidebar innovations. Android Authority, cited in Startup News FYI on November 20, noted: “Vertical tabs are one of the features we wish Chrome would steal from its rivals.” Google’s delay may stem from UX philosophy favoring minimalism, but user metrics likely tipped the scales.

Rollout timeline remains speculative—Canary to Dev, Beta, Stable could span months. Chrome Unboxed’s September 17 Threads post foresaw this: “After years of waiting, Google is finally working on a native vertical tabs feature.” FindArticles.com on November 20 confirmed: “Google is testing vertical tabs in desktop Chrome, finally honoring a long-standing request.”

For insiders, this signals broader redesigns, including tab freezing and groups syncing, as teased in Chrome’s X posts. With ChromeOS 142 emphasizing stability, vertical tabs could debut in Chrome 142 or later, reshaping developer tools and extensions ecosystems.

Industry Ramifications for Developers and Enterprises

Developers stand to benefit from standardized APIs for sidebar interactions, reducing extension dependencies. Enterprises, reliant on Chrome for fleet management, gain native tools curbing tab overload—key for remote work. Digital Trends warned on November 20: “Google is experimenting with vertical tabs in Chrome Canary, offering a sidebar layout to reduce tab clutter before a potential wider rollout.”
