I am trying to access WhatsApp Web and I get the following message:

WhatsApp Web works for Google Chrome 36+ To start using WhatsApp Web, update Chrome or use Mozilla Firefox, Safari, or Opera.

I run Chrome version 43+ so this makes no sense.

What seems to be the error?

  • Happens to me so often on so very many sites, I don't let it bother me any more. Some websites even complain that they can only work properly with browsers running under Windows as opposed to Linux. If I really need to visit such a site, I just change my useragent string.

  • They are probably using a technique to detect your browser version that can break at even slightest errors in data. Would be looking at their source code though to see what actually does it. Commented Jun 27, 2015 at 17:10
  • It started happening again. I resolved using WhatsApp Web in an incognito Chrome window. It works.

Whatever algorithm they're using to detect your browser is faulty. Unless and until they fix it, you should follow their advice and use a different browser.


After speaking with WhatsApp support the answer is that some extensions make the application think it's a another version of Chrome. It was indeed the answer. In my particular case it happened to be an extension called "Smooth Scroll".

  • Interesting, I had the same problem- then disabled 2 extensions: HD for YouTube and Chrome for Kindle Now I was able to access whatsapp via Chrome. then reenabled both extensions And I was still able to access whatsapp

  • For me, the extension that I had to disable was "FirePHP4Chrome". I guess they don't want us to be sneaking down the ajax calls :D

  • It happened to me today, and i have not installed any new extension in a really long time. so i am wondering if that's the issue Commented Oct 20, 2020 at 0:08
  • I tried disabling all extensions, ad blockers, miners blockers, etc. but no luck. The only way I got it working is in an incognito windows.
