How to find your browser version for a support request

To find your browser version, open its About page. Chrome, Edge and Firefox keep it in the menu or the settings, and Safari keeps it under the Safari menu on a Mac. Support teams need the full version number from that page, together with your operating system version. A web page can show something different, because browsers now freeze parts of what they report to websites, so the About page is the number to trust.

Where to find the version

Menu names move between releases, so if a path below has changed, search the settings for About.

Chrome and Edge

In Chrome, open the three-dot menu, go to Help, and choose About Google Chrome. In Edge, open Settings and more, go to Help and feedback, and choose About Microsoft Edge. Both pages show the full version and check for updates when they open. Chrome also has an internal page, chrome://version, that lists the browser version with the operating system, and Edge has edge://version.

Firefox

Open the menu, choose Help, then About Firefox. The about:support page lists the same version with more detail, which is useful when a technical report is needed.

Safari

On a Mac, open the Safari menu and choose About Safari. That number is the Safari version, not the macOS version, so check macOS separately under About This Mac in the Apple menu. On an iPhone or iPad, Safari is part of the system, so its version follows the iOS or iPadOS version, which you can read under Settings, General, About.

Why a page can show a frozen version

Every browser sends a user agent string with each request, and pages read it to work out the browser and the system. Browsers have shortened that string over time. The browser info tool reads it, so its answers can only be as detailed as the string.

Windows. Windows 10 and Windows 11 both appear as Windows NT 10.0 in the string. The tool shows "Windows 10 or 11" and notes that the string cannot tell them apart.
macOS. Chromium browsers and Safari report macOS as 10.15.7 whatever the real version is. The tool marks a macOS 10.15.7 reading as possibly frozen.
Browser number. Chrome keeps only the major version in the string, with zeros in place of the minor and build numbers. Headless Chrome 156 on Linux reports 156.0.0.0 in its user agent.

Browsers reduce the string to make a device harder to identify from it. The tool's FAQ gives the same reason.

Client Hints give the real version in Chromium

Chromium browsers also offer User-Agent Client Hints. By default a page receives only low-detail hints: the brand and major version, whether the device is mobile, and the platform name. A page that asks through navigator.userAgentData.getHighEntropyValues() can receive the full version list, the platform version and the full browser version. The browser info tool asks for these. It reads the platform version to name Windows 11, which reports 13 or higher, and it reads the platform version on a Mac to give the macOS version.

Firefox and Safari do not offer these hints, so on those browsers a page can only read the reduced string.

What to send to support

Send the details the form asks for. Usually that means:

The browser name and its full version, from the About page rather than a shortened number.
The operating system and its version: Windows 10 or Windows 11, or the macOS version under About This Mac.
The extensions that act on web pages, such as ad blockers, password managers and translators. The pages chrome://extensions, edge://extensions and about:addons list them.
The screen size and scaling, if the problem looks like a layout fault. The screen resolution tool reports the physical pixel estimate and the pixel ratio, and the screen resolution check explains those figures.
The exact address, the time, the steps you took and any error text.

The Copy all button in the browser info tool copies the summary and every row, including the user agent string. That string may be frozen, so send it only when the support team asks for it.

Edge cases

iPad in desktop mode. An iPad that has been asked for the desktop site reports itself as a Mac. The tool reads it as an iPad and notes that the version is not shown.
Browsers on iPhone and iPad. Every browser on these devices uses WebKit, so the browser names differ but the engine is the same.
Updates. Chrome and Edge download updates in the background and apply them after a restart. Restart the browser before you report a bug that a newer release may already have fixed.
Privacy tools. Extensions that change the user agent can make a page report a different browser. Disable them before you read the figures.
Is it up to date? The browser info page cannot know the newest release without asking a server, so it does not guess. Check the About page for updates instead.
