That is a great initiative. I have put it on the Open Science Feed.
https://reddit.com/r/Open_Science/comments/lj2tt5/new_open_access_helper_a_free_browser_extension/

For people already using Unpaywall: Do you have any estimates how much 
larger the number of OA versions becomes by including CORE?

I will have to be patient, my SUSE Linux distribution tends to wait a 
few versions to have more security problems fixed. So I got the warning: 
"This add-on requires a newer version of Firefox (at least version 
80.0). You are using Firefox 78.0." I thought I'd give you a heads up in 
case this limitation is not really in the software, but a matter of you 
quickly testing that it also works with older versions and telling Mozilla.

We recently started an initiative to make it easier to find translations 
of scientific articles. Would you be interested in including that kind 
of information into the add-on? Are there any requirements on the API of 
our database that would make it easier for you (or similar add-ons) to 
use it?

With best regards,
Victor

Unlike the common wisdom that if you are not paying for something you are the product, I'd like to assure you that this isn't the case with Open Access Helper (feel free to check the network traffic). It's my hobby and a ton of fun. I won't say no to a cup of tea, if you were to insist ;)
