It appears that messages are being added to a thread. by recipients or carbon copies. I believe it would be better for the threads to be formed by replies rather than by recipients. We may talk on different subjects which should not be threaded together with other subjects.  An unwanted result is that messages on one subject are hidden in threads of another subject.  Thank you. ...

I've been using Thunderbird and its Calendar for MANY years very happily 🙂 My old main computer is a W7 Lap and the Thunderbird Calendar in that version has the option to set up a Reminder Notification via Email. And it still works with no problem! I just was given a used Laptop computer that I did a clean install of w11 on, and installed Thunderbird and setup the Thunderbird Calendar to my Google Calendar with NO problems! EXCEPT: I just created a New Event and a Reminder for it, and to my chagrin, there is NO option to be notified by Email anymore !!! grrrrrr  😞 Please, I beg the developers to reinstate that option ! I use that for every event that I create! eg I take Prescription MEDS, and when I get the email reminder, I can delete the Email reminder to show myself that I've taken that prescription med at that time !!!! Please advise ! THANK YOU ... View more

reading the documentation it seems to me that the only way to bring a message filter from one account to others is to export the filter and import it into the desired account. It could be useful, when I decide to create a filter, to have the possibility to automatically spread it across all accounts ? I am referring in particular to the creation of filters on header "From, To, CC, Bcc" where in each account I have created a SPAM folder (with the same folder name) to trash messages.

When creating rules in mail rules, it would be good to add a '+' button to insert 'and/or' conditions for more detailed rule settings. Also, when using mail rules for auto-forwarding, there's an issue where image files in the email content don't load for the forwarded recipient, which should be fixed. Thank you. ... View more

One of Outlook's best features - and the whole point of threads IMHO - is the ability to quickly delete all emails in a thread that you don't actually need (because the text is all in the replies in the latest message). This tidies up your inbox in an instant and lets you see the wood for the trees instead of a forest of 'me too' replies to group messages. Any chance of something similar in Thunderbird now threads are pretty stable? Outlooks feature simply moves all the unneeded threads to a folder location (Deleted or other!) and you can protect flagged messages, unread, attachments etc from being 'cleaned'. Honestly, showing colleagues what happens when you press Ctrl-k in Outlook has often been the highlight of my week. The look of delight on their faces!!! ... View more

When I bring my Windows PC out of sleep, Thunderbird mindlessly slogs through all new emails one by one, even if they were deleted or opened using another device. For example, I have 10 new emails not in the local Thunderbird client - I have to sit though 10 slow notification popups one at a time, even if I have the client open or if the emails are deleted. It would be better to group them in one notification when there is a batch waiting to download, or implement some other more clever response. ... View more

Addresses with a "plus" element in the left hand side, a.k.a. sub-addresses, are effectively the same as the address without (the "naked" address), e.g. A.Non+Mozilla@example.com is equivalent to A.Non@example.com. Thunderbird should handle this intelligently, including some or all of associate any "plus" address with the corresponding account and/or contact, display the "plus" address as the "naked" address with a visually distinct label containing the "plus" element, reply to email sent to a "plus" address From that "plus" address, add an interface to simplify adding, removing or changing a "plus" element in the composer, and automate tagging and moving messages to folders based on the "plus" element. Handling replies may be tricky as senders will sometimes strip the name and change the case of the address. Ideally the address would be constructed as configured for the account with the addition of the plus element which can be easily edited in the composer. For instance, a reply to a.non+mozilla@example.com would be From: Another Non <A.Non+mozilla@example.com>  with the composer providing an easy method to change mozilla to Mozilla (or anything else). ...

Dear Thunderbird Team, I have been using Thunderbird for many months and greatly appreciate the free, open-source email software. Recently, I learned that only about 3% of users donate, and I wanted to contribute a small amount, such as €2. However, I noticed that the minimum donation is €20 for a one-time contribution or €9 monthly. I believe that many users, like myself, use Thunderbird because it’s free and often have limited financial resources. A minimum donation of €20 may be too high for some, discouraging them from donating at all. If you introduce the option to donate as little as €1, more users would likely be willing to contribute. A lower entry barrier would probably increase overall donation rates and bring in more support. I hope you consider this suggestion to further engage the community. Thank you for your excellent work on Thunderbird! Best regards Christer Haeberli ... View more

Proposal: Account-Centric Semantic Interaction View for Thunderbird (v2.0 with Implementation Details) Background and Motivation Thunderbird currently organizes its email client interface around individual messages, primarily displaying them in chronological order. However, contemporary communication behavior increasingly aligns with the question: “Who am I interacting with, and what have we exchanged?” Our vision is to transform Thunderbird from a traditional “Santa’s inbox” model into a unified communication platform through a phased innovation strategy. Vision for Evolution: Two-Phase Implementation Strategy Phase 1: UI and Interaction Model Enhancement (Current Proposal) Redesign Thunderbird’s message viewing interface from a message-centric approach to an account-centric paradigm, inspired by the intuitive interaction patterns of modern messaging platforms. Phase 2: Unified Communication Platform Integration (Future Direction) Introduce real-time messaging capabilities within the same interface to enable a seamless, integrated communication experience—eliminating the need to switch between tools. Key Enhancements in Phase 1 1. Account-Centric Design Sender as Semantic Anchor Transition from date-based grouping to sender-based grouping using the “From:” email address All messages from a sender (including forwards, CCs, and replies) belong to the same semantic thread Email protocol structures are preserved; only the presentation layer reflects semantic aggregation Design Considerations Users care more about “who they’re speaking to” than “what they received” Avoid fragmentation due to multi-party interactions Technically simple: requires only parsing of “From:” field 2. Every Message as a Semantic Event Each message becomes an interactive unit: Inline reply Semantic tagging (e.g., task / notify / alert) Mute / block / personal notes Track message status (e.g., active / awaiting reply / resolved) Reply Behavior Design Default: reply to original sender Optional: include TO/CC recipients Support for “Reply All” 3. Semantic Thread View Aggregation Strategy Threads grouped by sender (“From:”) Forwarded/CC/Reply messages do not shift semantic context TO/CC/Reply-To information shown as inline annotations UI Characteristics Conversation-style view akin to LINE, Telegram, WeChat Retains full compliance with email standards (e.g., reply-to integrity) Supports multimedia preview and display Annotation Examples “You are the main recipient” “You were CC’d” “Sent as part of a group discussion” “John forwarded this email” “Also sent to A and B” 4. Semantic Behavior Operations Sender list displayed persistently on the left (like contact list in chat apps) Center panel shows message thread and semantic event log Right panel includes inline controls for reply/mute/notes Supports contact grouping and intelligent classification Expandable Message View Default: simplified summary (subject, preview, key actions) On click: expanded view reveals headers (TO/CC), attachments, and full content Designed for power users who require full email context Technical Feasibility Implementable as a new view layer; no core architecture change required Leverages existing Thunderbird tag/threadID infrastructure Left-pane UI modifiable similarly to Unified Folder Plugin Ideal for initial development as a plugin, with later integration into the core Phase 2: Real-Time Communication Integration Real-Time Protocol Layer Integration with open standards like XMPP or Matrix Seamless transition between email and instant messaging modes Typing indicators and read receipts supported Advanced Interaction Features Voice and video call integration Real-time document collaboration and file sharing Calendar sync and meeting scheduling Implementation Strategy Incremental Rollout Provide new view mode as optional alternative Include interactive onboarding tutorials Gather user feedback to continuously refine Technical Roadmap Phase 1: Develop as extension/plugin to validate concept Phase 2: Core integration and modular architecture refactoring Long-term: Platform modularization for broader communication protocol support Anticipated Impact Evolve Thunderbird from a passive message client to an active semantic interaction console Deliver unified, intuitive communication workflows for users Reinvent email as a relevant, competitive format in the real-time messaging era Lay the groundwork for AI assistant integration, cross-platform coherence, and future meta-communication layers Conclusion Thunderbird doesn’t just need a new interface—it needs a redefinition of what communication means. This proposal introduces not merely a UI change, but a paradigm shift: from “hundreds of messages sent to me” to “who I’m interacting with, and what we’ve exchanged.” This phased innovation strategy addresses both immediate user pain points and Thunderbird’s long-term evolution into a forward-facing, unified communication hub. 🎁 Optional Appendices Context Navigation & History Log View original message ID and semantic thread for any email Detect if similar messages appear in other contexts Support manual thread merging (e.g., “these are actually the same conversation”) Semantic Filtering & Search Filter by intent, status, or media type Search within a semantic thread context ...

Hello; I would really like it if the "Get Messages" button (on the folder pane) could swap positions with the options ellipsis. (see screen grab) Although I have several accounts, there is only one that I use as my main account. (The secondary secondary accounts I only check once or twice a day. I really like that the folder pane button only gets messages from the account in focus. This saves time over polling all my accounts. (It might seem a minor delay, but it gradually gets kinda annoying. Also, the button being an active element of the UI, is more efficient nearer the other active elements, and the menu ellipsis being to the side seems more appropriate to it's frequency of use.) Ideally, I'd like toolbar buttons that could be assigned to individual accounts, but just moving the existing button would suit me just dandy. Thanks! ... View more

Currently, there is no easy way to subscribe to updates of all subfolders in the mail client included into the "parent" folder. File -> Subscribe -> I have to click through all the subfolders one by one to renew my subscription. It's inconvenient and time-consuming. It is necessary to make sure that when you mark a subscription to new emails in the "parent" folder, the subscription to updates of all subfolders occurs automatically. #thunderbird ... View more

Thunderbird would be a great email client if it natively incorporated the snooze and send later options into its interface, rather than through third-party vendors. The extensions for both features or tools are horrible and have nothing to do with Thunderbird's graphic design. I love Thunderbird, but the only thing that keeps me from making the final jump is that these options aren't native to the email client, which makes me feel like an incomplete and frustrating experience when I have to use third-party functions. Only in this way can Thunderbird surpass Outlook and any other email client. I hope this becomes a reality soon. Best regards. ... View more
