Google blacklisted some web browsers on Linux, blocking access to Google services

Google has issued a notice banning several popular Linux browsers, including Konqueror, Falkon and Qutebrowser, from signing in to Google services on the grounds that these browsers may be unsafe.

Mountain View didn't say when to start blocking the browsers, but one Konqueror user found out he couldn't log in to Google services on December 14, and posted information. This is on the Reddit forum. After that, many Reddit members conducted a test and confirmed that they could not log into Google accounts on Konqueror or Falkon platforms despite using many different devices. While trying to log in, they were asked by Google to try again in a different browser on the grounds that Konqueror or Falkon contained some security issues, as shown in the screenshot below:

The text of the message is given by Google as follows:

Couldn't sign you in

This browser or app may not be secure. Learn more

Try using a different browser. If you're already using a supported browser, you can refresh your screen and try again to sign in.

Provisional translation:

Login denied

This browser or application may not be secure. looking for more information

Try using a different browser. If you are using a supported browser, can reload the page and try logging in again.

In the 'Learn more' section of the above message, there is a link to the Google website that outlines the reasons why the browser in use is blocked from logging in:

1. Does not support JavaScript or turn off Javascript.
2. Contains unsafe or unsupported extensions.
3. Use automated testing frameworks.
4. Embedded in another application.

The owners of the browser included in the list have yet to comment on Google's announcement.
