We’re excited to announce major performance and stability improvements to Proton Mail Bridge.

It's now faster and easier to use your encrypted #ProtonMail inbox with your favorite email client, such as #outlook, @thunderbird, and #AppleMail.

Starting today, Proton Mail Bridge is using a new IMAP library, Gluon, which vastly improves the performance & stability.

Give it a try: proton.me/mail/bridge. If you're already using Bridge, you'll receive the update over the next few weeks.

I have actually been looking at Protonmail recently, wondering how compatibility with @thunderbird was. So this is very good news.

@olividir The very person running this Thunderbird account (e.g. @killyourfm) uses ProtonMail + Thunderbird daily, and it's worked consistently well on Linux, macOS and Windows.
