If you want to migrate your Thunderbird to a Gmail account, I would suggest you use professional software like WholeClear Thunderbird Converter. It's excellent software that can migrate Thunderbird emails to Gmail and other cloud apps and output formats such as Yahoo Mail, Hotmail, Office 365, Outlook, PDF, HTML, NSF, MSG, etc. It's a flexible software that gives so many options and features to make the conversion easy and fast. It reliably and seamlessly converts data without making changes to the original data. It keeps the folder hierarchy maintained, and all your email properties stay intact before and after the conversion. It saves you from unnecessary trouble and saves both time and energy. You can check out the demo version for free without paying a penny to try its features and functions.
