Brave Browser - Incorrect detection of user agent string

[alfreddagenais]

I'm using Brave Browser version 1.25.72 Chromium: 91.0.4472.101 (Build officiel) (x86_64)

My agent string is :
Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/91.0.4472.101 Safari/537.36

On version 2.1 of WhichBrowser/Parser-PHP they show me : Chrome Dev 91.0.4472.101 on macOS Catalina 10.15
On version 2.1.2 of WhichBrowser/Parser-PHP they show me : an unknown browser

Brave had a User-Agent of its own in the first few months of its existence, but removed it in April 2016 . The history books (git commit logs) show that Brave removed the “Brave/Version” component from their User-Agent string to make it more difficult to fingerprint the browser.

On a positive note, you can now reliably detect Brave using the following test (as of 2020):

(navigator.brave && await navigator.brave.isBrave() || false)

We can detect Brave Browser using client hints ua, comes out like this:

Sec-CH-UA: Brave Browser 79

p.s. would love to see admins thoughts about detecting Brave browser.

Vivaldi masks as Chrome for similar reasons (many sites would block Vivaldi or send broken code if it was not Chrome)
