Great extension, although I had one problem with it so far, concerning the addition of domains that have more than one .something after the domain's name.

I'm not very tech savvy so I'm not sure about the best way to phrase this, but, basically, it seems the problem concerns domains that are specific to some countries. So, for example, ''something.co.uk'', or ''something.com.fr''. Whenever I try to add these sites to the block list, they are added with a comma instead of a dot preceding the country defining part of the domain (like ''something.co,uk''), and the extension doesn't work on these sites. I've tried both swapping the comma for a dot (something.co.uk) and removing the country defining part entirely (something.co) and leaving just the .com or the .co, etc, but neither made the extension be triggered by entering the sites.

Also, I had an idea that I'd like to share: one thing that I think could be interesting would be for the ''I don't want to open (...)'' button to be accessible from the start, whilst the ''continue on (...)'' would continue to appear only after the take a deep breath animation finished, so the person using the extension could have a bigger chance of choosing to refrain from using the site. Maybe it could be a toggleable customization.
