What is the user agent of Puffin Web Browser?

All Puffin browsers, including Puffin Web Browser, Puffin Web Browser Free, and Puffin Academy use the same format. Here is an example of the user agent of Puffin Web Browser 6.1.4:

Mozilla/5.0 (Linux; Android 7.0; SM-G925T Build/NRD90M; en-us) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/42.0.2311.135 Mobile Safari/537.36 Puffin/

"Puffin/6.1.4IT" is appended at the end of the user agent for Puffin Web Browser. "Puffin" is the keyword. If Puffin is found in the user agent, it is from the Puffin Web Browser.

"Mobile" is the hint showing Puffin is in mobile mode. With or without the hint, as long as the keyword "Puffin" exists, it's from the Puffin Web Browser.

"" is the version number, where 6 is the major version and .1.4.16005 is the minor version.

The last two letters with 5 possible combinations represent the OS and the device type:

IP: iOS-Phone

IT: iOS-Tablet

AP: Android-Phone

AT: Android-Tablet

WD: Windows-Desktop

LD: Linux-Desktop

Cannot connect to server

Puffin Browser is a remote browser. The website content displayed in Puffin is actually executed on our servers.

Please ensure that the following IP addresses are not blocked by your Proxy, firewall, or antivirus software:





Wrong Geo-location

Puffin leverages our servers in the USA and Singapore to improve the user's web browsing experience'.

The side effect is that the websites receive the Puffin server's IP rather than the IP of your current device.

Although Puffin passes your IP to websites via X-Forwarded-For, some websites do not support this standard and cannot accurately detect your region.

How does Incognito browsing work?

When you browse under Incognito mode, Puffin Browser does not save your browsing history or any information entered in forms. Cookies and site data are deleted when you leave Incognito mode. Please note that Incognito mode is only available when the Cloud Server is turned on.

About the default search engine.

Puffin now offers users more choices of the default search engine.

Go to the main menu > Settings (the gear icon) > "Search engine" to select your preferred searching engine.

Support for Download-to-Cloud 3rd party services

Since June 2017, we will no longer support "Download to Cloud for Dropbox" integration. We'll continue to support "Download to Cloud for Google Drive".

The Dropbox integration APIs do not offer the kind of capabilities we need to expand our app's features in the future. If you would like to use Download-to-Cloud feature, we recommend switching to Google Drive (the basic 15GB Google Drive service is provided for free to everyone).


Why do I get notifications from Google or other websites when I login using Puffin Browser?

Some websites will send notifications to you if your latest log on location is very different from your normal usage pattern. Others will send notifications for every login.

Puffin is a remote browser. The real browser is running on our servers, which is located in San Jose, California, U.S and Singapore. Once our server renders a webpage, it sends the results to Puffin client app, and the app displays the result in a certain sequence.

When you use Puffin Browser to log in to your accounts, websites receive the IP address of our servers in either Northern California in the United States or Singapore.

In both cases, if you are sure you have just logged in, then there is no need to worry.

If you are unsure, you can check your current Puffin server's IP address against the address provided in the notification email.

You can use Puffin Browser to access the following website, and you will see your current server's IP address. Your device's local IP address as seen from our servers will be shown in the X-Forwarded-For header.


In most cases, Puffin Browser performs much like a proxy server.

Our users' privacy is our top concern. Please refer to our privacy policy for more information.


How to reconnect to our servers

Puffin should auto-resume its connection to our server while your device recovering from no signal. You can enforce it to do so. Please open menu and click "Reconnect to Server" icon.

If Puffin still cannot connect to our server, please visit our feedback page and provide us more information.

How to access Flash game or Flash video content?

Puffin browser now opens mobile web pages by default. However, most websites do not show Flash content in their mobile pages. To access Flash content, please click the main menu at the top right, and choose 'Request Desktop site'. Puffin will then reopen the same page in the desktop mode.

If you prefer to open new tabs in the desktop mode every time, please go to Settings and enable the 'Always Desktop Site' option.

We will have to stop supporting Puffin 6 and Android 4.0 in April 2018.
