Google sees user agent


Beta Tester
Google seems to be able to find the correct user agent. If I type "my user agent" the correct one comes straight up. And if you then click on one of the test sites from that google results page, that website also knows the correct user agent.

But if you copy and paste one of those sites it shows the user agent I entered instead (I just put Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2228.0 Safari/537.36 for testing).

Adguard 6.2.437.2171
Firefox 57.0.4
Windows 10

Edit: An immediate edit before I actually post. I just realised if I select the link from the google results page, right click, and select "Open link in new tab" (the actual text of the website, not the google link!) that also shows my actual user agent. Copy and pasting that text still hides it.

Anyone know what is happening, or if I am doing something wrong?
