Does Mozilla Thunderbird allow MBOX to HTML conversion?

Yes, Mozilla Thunderbird does allow MBOX to HTML conversion, but not as a direct bulk conversion feature. I also explored this when I wanted to open my archived emails in a web browser. At first, I expected Thunderbird to convert entire MBOX files into HTML automatically, but the process is more manual.
Thunderbird can open MBOX files and lets users save individual email messages as HTML files. This means you can view or export emails in a browser-friendly format, but each message usually needs to be handled separately. For a small number of emails, this works fine, but it becomes slow and repetitive when dealing with large mailbox files or multiple folders.
Because of this limitation, many users prefer the BLR MBOX Converter Tool for easier MBOX to HTML conversion. It can convert multiple emails at once while preserving formatting, metadata, inline images, and folder structure, making the exported HTML files much easier to manage and access in any web browser.
