When it comes to catching up with the latest news in the world of email clients, a lot of people still rely on Mozilla’s Thunderbird. While it’s been around for a good long time, as a long-time fan of the app myself, I’m always glad to see new Thunderbird versions come out.
Mozilla Thunderbird is one of the most used email clients out there, with around 43% of all emails being read by people using it. The latest version, Thunderbird 91, has been released to the public and had alot of new features added.
To make it easier for Thunderbird users to discover and install extensions, the new version of the main program (Thunderbird 91) now contains a small section of extensions that are installed by default. The extensions are installed automatically after Thunderbird is installed, and can be managed from this section.
The famous Thunderbird software now has a new version available for download. The open source mail and RSS reader has achieved version 91, matching Firefox in terms of release number. A number of modifications have been made in the new edition. Improved Set-Up Wizard, Better Calendar Support, and Multi-Process Implementation all have the potential to increase speed.
Thunderbird is my preferred email program. It’s on every PC I own, and it works with any operating system I use. It’s reliable, has all of the functionality you’ll need, allows add-ons, and includes an RSS reader. I’ve been using it for a long time and have had nothing but good experiences with it.
Since version 80, the Thunderbird team has been working on the new version in the beta channel. Firefox 91 has now been matched to the version number. However, if you were hoping for a fresh user interface, you will be disappointed.
The updated version is presently only available for manual download and installation. The built-in updater will make the latest version of the mail client widely accessible later. The list of new features is extensive.
