Lookbehinds are only supported in Chrome
http://kangax.github.io/compat-table/es2016plus/#test-RegExp_Lookbehind_Assertions
Note that the regexp seems to be broken in Chrome too, without escaping the +
let email = "support+account@domain.com"
email.match(/(?<=\+)[^.]+(?=@)/gi);
> ["account"]
Implementation is tracked in bug 1225665. Not sure if duping against that bug is the best choice, in case triagers can fix it.
