Unfortunately we cannot debug or support issues when using a third party plugin, the implementation we use is supported by PayPal so the issue is related to the plugin. For obvious reasons we are unable to check for issues with every single plugin provider. I will take a look and see if I can see anything obvious that is causing the issue.
EDIT: I have had a bit of a research and it appears Privacy Badger is well known for breaking things in the name of privacy so I am not surprised there are issues in this case.

I am not sure why you are concerend you know TGC are a reputable company its not as if you are ordering from someone you have never heard of. Seeing a payment providers login inside another website is not unusual by any means.
For the PayPal checkout you are on the PayPal website, it is secure and all details are transferred direct to PayPal. The checkout process is embedded in an iframe on the website you are ordering from, this is an implementation supported by PayPal themselves and is a valid checkout method used on many sites.
We have no immediate plans to change the implementation. If you are unsure on using PayPal there is also a card payment option powered by Stripe which is also secure and used across tens of thousands of websites worldwide.
