These Top 20 Thunderbird Feature Requests Need Your Vote

At Thunderbird, we enthusiastically embrace open development. That means more than making our software open-source. It also means being as transparent as possible, and communicating frequently with our global family of users. 

We want that communication to go both ways! Which is why Mozilla Connect is such an important tool for telling us the features you want to see get developed for Thunderbird (and soon, for our entire family of products and services). Mozilla Connect is an easy-to-use community tool that can help shape future Thunderbird (and Firefox) releases. It allows you to post a feature request, contribute your opinions to existing ones, and give kudos to the features you believe in.

We’re actively monitoring your Thunderbird feature suggestions at Mozilla Connect, but “voting up” ideas from the community is crucial. There are currently 287 Thunderbird ideas at Connect, many of which need wider discussion and votes.

With that in mind, we collected the Top 20 feature requests and linked them below. Check them out, and please consider lending your voice and your votes to these ideas – and the other 267 – if you believe in them.

Hi there! Happy to say that we’re now planning an iOS version of Thunderbird, but work is in the very early stages.

Requesting team to please change the ancient layout of this great mail client.

That’s in the works and it will be visible with Thunderbird 115.

Top of my wishlist : a contact autocompletion in the To: field, that would suggest the most frequent contact and address instead of the least probable one. For instance : the colleague i write to and who writes to me 10 times a day, instead of the guy with the same first name that wrote once me 12 years ago. Any other feature seem such a gadget…

Please make export & import for single features easier. Especially for filters. Now it’s too troublesome.

Jason Evangelho wrote on

Be sure to add this idea to Mozilla Connect. It’s very important that the suggestions land there, from the community (not just here as a blog comment).

Hello there,

Loving the new design, but as mentioned before regarding the development of thunderbird and it being a pile of poorly placed blocks:

Thunderbird should be toolkit agnostic, and should look good on windows, Linux and MacOS and not focus only on better GTK support (thunderbird looks meh on KDE).

As for features, would be nice to have thunderbird focus on email, calendar and contacts only. RSS, chat, web browser and PDF reader should be toss aside for safety reason and to declutter code.

There are already good solutions for RSS, chat, web browsing and PDF editing on any OS, not to mention that for safety reasons, having way too many features opens the door for exploits with malicious purposes.

Focusing on email, calendar and contacts while restricting email content like JS, CSS etc would be awesome to safeguard the user space of said exploits.

Hello Jason,

I had a quick look at the ‘’ repo the other day, but couldn’t find a (Kotlin) multiplatform development branch there. Or what technology are you using?
Is there anything publicly available yet, and if so, where?

Jason Evangelho wrote on

Hi Nils, are you asking about the iOS version by chance? We haven’t started development on that yet, since we want to get the Android version polished and released first. Then we will begin hiring for development of the iOS version.

it wasnt easy to install

None of that. Instead, a faster and more effective search function would be nice.

So we should do full MS Exchange support. Many companies still use it and the Web App is horrible, but often the only way to use it. Please integrate OWL.

We need a tray icon.

KGIII wrote on

I went through the list and I don’t actually care about any of those features.

I just want Thunderbird to be a good email client. It mostly is.

DVD B. wrote on

As many have already said in the request thread, I would *gladly* even pay for a fully fledged ‘Mozmail’ service with encrypted mail and email address obfuscation and whatnot. Consider me a ‘wanted to use Proton Mail but couldn’t get it to work in Thunderbird’ refugee.
