Emails sent to me are sometime returned to the sender with the message "Inbox full" even though I have maybe less than 100 emails in the Inbox and I regularly compact them. How can I increase the storage space?

Question Emails sent to me are sometime returned to the sender with the message "Inbox full" even though I have maybe less than 100 emails in the Inbox and I regularly compact them. I delete emails from the Inbox and the Sent and Trash boxes to overcome this. How can I increase the storage space to stop this happening?

Hi terrybohle1938,

Firefox is a web browser. It provides access to online content. Things like your email are handled by the content provider. Who is your email provider? You'll have better luck consulting their documentation.

That being said, deleting only email is a great way to free up space. Another option would be to purchase a "Premium" account if your email provider offers this service. Many times more storage space is offered as part of paid subscription.

Hopefully this helps!
