Instead of click-to-copy, you could do click-to-highlight, so that "right-click > Copy" highlights the text on right-click if it's not initially selected. There is some subtlety in the logic, because it shouldn't interfere when the user manually selects a substring. For a demo of click-to-highlight, install IPvFoo and use your mouse in the popup window. See the 'selectWholeAddress' function in https://github.com/pmarks-net/ipvfoo/blob/master/src/popup.j...

I was recently looking for IPv4/IPv6-only HTTP services hosted by major CDNs (for https://github.com/pmarks-net/ipvfoo/issues/60), and found these: Cloudflare: https://ipv4.icanhazip.com + https://ipv6.icanhazip.com Akamai: https://ipv4.whatismyip.akamai.com + https://ipv6.whatismyip.akamai.com The problem with https://checkip.amazonaws.com is that it neither supports IPv6, nor claims that it will remain IPv4-only, so it's not clear what you'll get in the future.

Given all the recent chatter about Chrome turning evil, I spent a few days polishing my Chrome extension (IPvFoo, for observing the IPv6 transition) to run properly on Firefox. Technically it's been available since 2017, but there were numerous compatibility bugs that I was hoping Firefox would fix eventually. I finally decided to just hack around the remaining ones, so Chrome/Firefox are now at feature parity from a common codebase: https://github.com/pmarks-net/ipvfoo
