Be careful with old versions! These versions are displayed for testing and reference purposes.You should always use the latest version of an add-on.
Latest version
Version 3.15.55
Released Sep 10, 2026 - 370.97 KB
Works with firefox 140.0 and later
Same code base as 3.15.54 (approved). Changes in this version: (1) the per-contact notes feature ships enabled by default again (it was disabled while we investigated an unrelated session issue, now fixed); (2) the daily recap prompt asks for a final "agreed items" block; (3) the popup lists the notes written today, read from chrome.storage.local only — notes are never sent to any server, as stated in our privacy policy. No new requests, no new permissions, no new hosts.

BUILD (reproducible; the source package ZapVox-v3.15.55-SOURCE.zip is uploaded with this version and contains README-BUILD.md with the same steps):
- Node.js v22.23.2, npm 10. No other tools.
- npm ci (at the package root)
- cd apps/extension && npm run build:firefox
- Output: apps/extension/dist-firefox/ — matches the submitted zip byte for byte (manifest = manifest.firefox.json). node scripts/guarda-zip-release.js performs that comparison.
- Bundler: Vite 5. No remote code is loaded at runtime; no minified file is treated as source (all TypeScript is in apps/extension/src/).

The extension requires a ZapVox account (login). We do not publish shared credentials; if you need a dedicated test account for review, please request it and we will provision one.

Version diagnostics: the extension now tells the server which version is installed, alongside a request it already made. That lets us see whether an update has reached everyone and react faster when it hasn't.

Version 3.15.39
Released Sep 8, 2026 - 367.37 KB
Works with firefox 140.0 and later
Transcripts of GROUP audio now find their way back to the right conversation: if you switch conversations while the AI transcribes, delivery opens the originating group, checks the destination and posts it there, the same behaviour direct chats already had. The speaker is identified by WhatsApp itself, from the message record rather than from reading the screen, so in a group the author of that audio is the one shown and your own audio shows as yours. Opening the right conversation is faster and sturdier. If auto-send cannot complete, the message box is left clean instead of holding text you did not send, and a second write attempt is made in the already verified conversation. Per-contact notes remain paused for maintenance; the switch in Settings explains why, and everything already written stays stored on your computer.

Version 3.15.37
Released Sep 7, 2026 - 366.91 KB
Works with firefox 140.0 and later
- Auto-send delivers the transcript to the conversation the audio came from: it waits for a free moment instead of giving up, and if it cannot complete, the message box is left clean rather than holding text you did not send. - The on-screen notice names the conversation the audio came from, not whichever chat happens to be open. - Per-contact notes are paused for maintenance in this release. The switch in Settings explains why when you try to turn it on, and everything already written stays stored on your computer, untouched.

Version 3.15.30
Released Sep 7, 2026 - 366.23 KB
Works with firefox 140.0 and later
• Three features now ship turned off, temporarily: per-contact notes, chat names in transcription and the stuck-message notice. All three stay whole and come back with one click in Settings; whatever was written in the notes is still stored, waiting.

• Connection diagnostics get sharper: every internal report now records which features were active at the time, with the exact place where any of our readings met something unexpected.

Version 3.15.28
Released Sep 7, 2026 - 365.7 KB
Works with firefox 140.0 and later
• Per-chat settings ship turned off, temporarily. The feature stays whole and comes back with one click in Settings -> "Per-chat settings". Whatever was chosen in each chat is still stored, waiting. In the meantime, language, translation, sending and automatic transcription follow the general setting, as before.

• Internal scans now have a time budget. Every routine that walks the message list is timed in a real browser, on a large account, before any release. None may hold the page's processing beyond the ceiling, so WhatsApp keeps responding while ZapVox works.

Version 3.15.26
Released Sep 7, 2026 - 364.92 KB
Works with firefox 140.0 and later
Each chat note now has a colour — yellow, green or red — chosen from three dots on the note toolbar; the colour is kept per chat and applies to the pinned square too. Internal sweeps (deleted messages, audios, chats) now walk the message list in short pieces and hand processing back to the page in between, so the tab stays responsive on accounts with many messages loaded. The button that moves the note to the other side joined the toolbar next to the text-size controls.

Released Sep 6, 2026 - 363.83 KB

Automatic sending is more resilient: the check that guards against a cut-off message now looks at whether every character reached the message box, list markers in summaries are sent as bullet characters so the editor does not reformat them, and the message box is emptied through a path that also works while the tab sits in the background. When the box cannot take the text, delivery is retried through the internal dispatcher instead of stopping.

Released Sep 6, 2026 - 363.02 KB
Works with firefox 140.0 and later
Anonymous diagnostics now also record when automatic sending holds a transcript back because the chat of origin could not be confirmed: only the reason and whether it was a group or a direct chat. No text, chat name or phone number is ever sent, and nothing is sent unless the user turned anonymous diagnostics on.

Version 3.15.23
Released Sep 6, 2026 - 362.93 KB
Works with firefox 140.0 and later
Automatic sending confirms the chat first: before the transcript goes into the message box, ZapVox asks WhatsApp which chat that audio belongs to and compares it with the chat currently on screen. If it is the same chat, the text is typed there. If it is a different one, the text is delivered inside the chat the audio came from. Without that confirmation the extension stops and tells the user on screen, and the transcript stays in the ZapVox card with a Copy button.

Released Sep 6, 2026 - 362.39 KB
Works with firefox 140.0 and later
One automatic send per audio: transcribing the same audio again refreshes the ZapVox card so you can read it once more, without repeating the message in the chat; a discreet notice tells you the text for that audio has already gone out.

Also in this line of releases: your own audio is left alone until WhatsApp confirms it was sent, transcription/summary/translation go out on separate lines, the note picks a side (⇄), and a text-free local diagnostic log of connection states.

Version 3.15.20
Released Sep 6, 2026 - 361.78 KB
Works with firefox 140.0 and later
Your own audio: the text goes out after the audio. Transcription of an audio you recorded starts only once WhatsApp confirms it was sent; until then an ⏳ hourglass shows, and the automatic sending of a transcription or translation always happens after the audio has reached the server.

The note picks a side (⇄ button), transcription/summary/translation on separate lines, WhatsApp session watch with reconnect-then-notice, and a text-free local diagnostic log (connection states, timestamps, and the send stages of your own audio) that is sent to the ZapVox team under the same anonymous opt-in diagnostics when something gets stuck.

Version 3.15.19
Released Sep 6, 2026 - 361.24 KB
Works with firefox 140.0 and later
The note picks a side: the ⇄ button in the note header moves the yellow paper to the left of the chat (below the name at the top of the chat) or back to the right; the pinned square follows, and the choice is saved.

Transcription, summary and translation go out on separate lines in the automatically sent message.

WhatsApp session watch: if this tab's connection drops and does not come back within 30 seconds, ZapVox asks WhatsApp itself to reconnect, without reloading; only after one minute does the notice with the reload button appear — including when WhatsApp was opened in another tab that has since closed. A text-free diagnostic log (connection states and timestamps only) is kept in browser storage and, when the notice appears, is sent to the ZapVox team under the same anonymous opt-in diagnostics.

While WhatsApp is still uploading an audio message you recorded, ZapVox requests no download of it.

Works with firefox 140.0 and later
Transcription, summary and translation now go out on separate lines in the automatically sent message, exactly as shown in the ZapVox card.

WhatsApp session watch: if this tab's connection drops and does not come back within 30 seconds, ZapVox asks WhatsApp itself to reconnect, without reloading. Only if it is still down after one minute does the notice with the reload button appear. A local, text-free diagnostic log (connection states and timestamps only) is kept in browser storage and survives a page reload.

While WhatsApp is still uploading an audio message you recorded, ZapVox requests no download of it; transcription uses the local file.

Works with firefox 140.0 and later
New in this version:
- The pinned note is now a small square: the same yellow paper and handwriting as the note, in a small size, floating in the corner of the chat. It shows the whole text and scrolls when there is more below. Clicking it opens the note for editing; while the note is open, it steps aside.
- Pin a note from inside it with the 📍 Pin button; Pin again removes the square (the note stays saved).
- Hover the 📝 pin in the chat header and read the beginning of the note without opening it.
- Audio you just recorded: while WhatsApp finishes sending it, the transcribe button shows an hourglass and returns to normal on its own.
- When WhatsApp Web loses its message session in a tab, ZapVox tells you on screen and offers a button that unlocks and reloads the tab.

Works with firefox 140.0 and later
New in this version:
- Pin a note to the chat header. Inside a note, the new 📍 Pin button keeps a one-line summary of it next to the 📝 in the chat header, so you know who this is as soon as you open the conversation. Clicking the summary opens the note for editing; Pin again removes the summary (the note stays saved).
- Hover the 📝 pin and read the beginning of the note without opening it.
- Audio you just recorded: while WhatsApp finishes sending it, the transcribe button shows an hourglass and returns to normal on its own; the transcription comes on the next click.
- When WhatsApp Web loses its message session in a tab (the page looks normal but nothing you send is delivered), ZapVox now tells you on screen and offers a button that unlocks and reloads the tab. Scheduled messages are postponed instead of being sent into that state.

Bug fix release.
- When WhatsApp Web loses its message session in a tab, you now get told. In that state the page still looks normal, but nothing you send reaches the other person and reloading may not respond. ZapVox recognises it, says so on screen and offers a button that unlocks and reloads the tab.
- A scheduled message is no longer dispatched into a tab in that state: it waits for the next minute instead.
- The "stuck message" notice no longer appears when a message is simply queued by WhatsApp.
- Internal diagnostics now record the message-stream state, not only the socket state.

3.15.9 — The whole message: before sending a transcription through the internal path (when you have already switched chats), ZapVox checks that the complete text is in the box — and long texts fit in full.

3.15.9 — Mensagem inteira: antes de enviar uma transcrição pelo envio interno (quando você já trocou de conversa), o ZapVox confere que o texto completo está na caixa — e textos longos cabem por inteiro.

v3.15.8 — Ainda mais leve: o ZapVox lembra quais mensagens já avaliou, mesmo quando o WhatsApp redesenha a tela. Aba do WhatsApp mais leve (a varredura só acorda com linha ou áudio novo).

Ajustes por conversa completos, com painel em cascata; Free até 10 conversas com ajuste; ao atualizar, a versão antiga sai de cena sozinha.

v3.15.8 — Lighter still: ZapVox remembers which messages it has already evaluated, even when WhatsApp redraws the screen. Lighter WhatsApp tab (the scan only wakes for a new row or voice note). Main-thread watchdog and a one-time welcome at the first login. Complete per-chat settings with a cascading panel; Free up to 10 chats with custom settings; after an update, the old version steps aside on its own.
