According to a statement released by Mozilla on July 6, 2012, the company looks to be decreasing its focus on Mozilla Thunderbird development due to its failed feature upgrades. Mozilla's new development approach involves issuing "Extended Support Releases," focusing only on security and maintenance updates and handing over new feature development to the community.

Mozilla Thunderbird users have reported several issues. Being unable to utilize a schedule or to-do list since you don't have access to either. The user interface is old, there is no support for drag-and-drop features, and several features are unavailable.

In addition, there are still some kinks to work out, such as when you click on a subject line and are sent to the incorrect email or when a temporary topic suddenly vanishes.

Do you need to remove Mozilla Thunderbird to resolve issues? Do you want to know how to remove it from your computer without leaving any traces? Never fear! This page contains comprehensive steps for removing Mozilla Thunderbird from your computer.

What Is Thunderbird?

Thunderbird is an open-source, free, cross-platform email and news (NNTP) client developed by the Mozilla Foundation. The Mozilla Firefox project, which strives to develop a new browser, served as inspiration for this concept.

Mozilla Thunderbird and other email clients utilize IMAP (Internet Message Access Protocol) to get messages from a mail server. The email client may be programmed to automatically check for new messages from the email provider's server at a certain time each day.

Because Mozilla Thunderbird stores your email locally on your computer, you can read it even if you aren't connected to the internet. Since emails are often downloaded to a computer, it is important to check them with an up-to-date anti-virus tool periodically.
