Hello Rajes, First of all : would you please remove those email addresses ? This is a public forum - anybody could start sending spam ..... Then : Firefox doesn't 'do' email - it's a browser. Please take a look at this article : https://support.mozilla.org/en-US/kb/problems-with-email-how-to-find-help In case you're using Thunderbird - please see : https://support.mozilla.org/en-US/kb/cannot-receive-messages If that doesn't solve the problem, and you ''are'' using Thunderbird : please let us know and we will have this thread moved to the Thunderbird support forum.
