Whenever users want to send large files to someone else, they often choose to upload the files to a file sharing service rather than attach them to an email.

Luckily, Thunderbird offers an easy solution for uploading large files to storage services without any hassle. Continue reading to learn how to enable and use this feature.

This Thunderbird feature is currently available in beta version only and will be pushed to stable release soon.
