You will always get results like that, because it's how the browsers' engines are identified (see user-agent article on Wikipedia).

You have to manually parse the user-agent string, something like:

if 'Chrome' in browser:
  users_browser = 'chrome'

In new versions 2.* every request includes browser info by calling request.user_agent()

That function uses:

from gluon.contrib import user_agent_parser

Example info:

browser :   name    :   Firefox
        version :   15.0.1
is_mobile:  False
is_tablet:  False
os  :   name    :   Windows
        version :   NT 6.1

This info is always in session._user_agent

So you can check:

if session._user_agent['browser']['name']=='Chrome':
    ...your code

I think you should do what Zaur has suggested assuming all you want to detect is Chrome. Otherwise you can check httpagentparser
