Nice app Gmail checker.

This is a good addons but they add all the gmail when you login I hope it will add sync system when we login there it will add out previous gmail. Thank you

Best Gmail extension!

خيلي خوبه ممنون از سازندش و از زبان فارسي هم پشتیبانی میکنه

Works like a charm on chrome-based browsers, but not working on Firefox 86.
