What Browser Am I Using? A Copyable Report for Support Tickets
Open this page and it shows the browser, version and system you are on, then lists a table of settings and features. Press one button to copy it all for a developer or a help desk.
The details are read from your browser on this page and shown to you only. Nothing is sent anywhere or stored.
When a bug only happens on your computer
The most common reason to open this page is a message that begins with: it works for me, which browser are you on? A site owner testing a form, a marketer who sees a broken banner or a customer sending a screenshot to a developer all hit the same gap. Without the browser, the version and the system, a bug is very hard to reproduce.
The page gives a headline such as the browser name with its main version number and the system it runs on, then a table with the rest. The Copy the report button turns the table into plain lines of text that you can paste into an email, a chat or a ticket.
The page also says how to check for an update in your own browser, using its menus, so you can rule out an old version before you report anything.
What is in the table
| Row | What it tells a developer |
|---|---|
| Browser, Engine, System | Which program and rendering engine draw the page, and on what operating system |
| Device | Phone, tablet or computer, guessed from the browser's own text |
| Screen, Window, Pixel ratio | Display size, the size of the page area and the density |
| Language, Time zone | The languages your browser asks sites for and your zone |
| Cookies, Dark mode, Reduced motion, Touch screen | Settings that change how a page behaves |
| WebGL, WebGPU | Whether graphics features are available |
| Do Not Track, CPU threads, User agent | Privacy flag, processor threads the browser reports, and the full identification string |
A few of these are the usual suspects in odd bugs. Reduced motion changes animations, dark mode can break a design that only had a light theme, and a blocked cookie setting stops some forms and logins from working.
Where the answer is limited
Browsers hide some details on purpose, to make it harder to track people. The page says so when it notices it, instead of guessing.
- Mac version. Some browsers report every Mac with the same operating system number, so the exact macOS version cannot be read.
- Windows 10 or 11. Without extra information from the browser, both appear the same.
- Chrome version digits. The identification string shows only the main number and fills the rest with zeros. The page asks for the fuller list where the browser offers it.
- Brave and other Chromium browsers. They can present themselves as Chrome. The page checks for Brave directly, but a lesser known browser may still appear under a familiar name.
- iPhone and iPad. Every browser there uses the same engine, so the engine row says so, while the browser name comes from its own text.
Getting more from a bug report
Paste the report, then add three things the tool cannot know: the page address, the steps you took and what you expected to see. A short screenshot helps too. With those four items a developer can usually reproduce the problem on a matching browser within minutes.
If the issue appears on a live site we look after, a report like this also tells us whether to look at the layout, a script or a setting. Our Webflow maintenance page describes the checks and fixes that sit behind that kind of report.
Frequently asked questions
How do I find out which browser I use?
Open this page. The headline shows the browser name with its main version, and the line under it names the operating system.
How do I check whether my browser is out of date?
The page prints a hint for your browser, usually a path through its main menu to an About screen. That screen checks for updates and installs them.
Why does it say Windows 10 or 11?
Some browsers describe both systems in the same way. When the browser gives more detail, the page separates them.
Why is my Mac version missing?
Certain browsers report a fixed macOS number for privacy. In that case the page shows a note instead of a guess.
What is the user agent line?
It is the identification text your browser sends to websites. The report includes it because developers sometimes need the exact wording.
Does the page keep or send my browser details?
No. It reads them in your browser and shows them to you. Copying the report is your choice, and it goes only to your clipboard.
