Everything you need to install Comix Downloader and start saving chapters from comix.to. Pick your platform below.
Overview
Comix Downloader is a Manifest V3 browser extension that adds download buttons directly to every comix.to title page. You can grab a single chapter, or download an entire series at once — every chapter is fetched, packaged into its own folder, and bundled into a single ZIP, named and sorted.
Install
The fastest path is the signed Firefox add-on. Chrome and Android each take a couple of extra steps, covered below.
Firefox (desktop)
The extension is published and signed on Mozilla Add-ons — one click to install.
- Open the listing on addons.mozilla.org.
- Click Add to Firefox and confirm the permissions prompt.
- Visit any comix.to title page — the buttons appear automatically.
Chrome (load unpacked)
Chrome installs from the source folder in developer mode.
- Download the repo ZIP and unzip it.
- Open Chrome and go to
chrome://extensions. - Toggle Developer mode on (top-right).
- Click Load unpacked and select the unzipped folder.
- Head to any comix.to title page — buttons appear automatically.
Android
There are three ways to read on Android, depending on what you want.
Option A — Mihon (recommended for offline reading). You get the same download capability through Mihon's native UI, with auto-updates.
- Install Mihon on your device.
- Open Mihon → More → Settings → Browse → Extension repos.
- Tap + and paste the source URL below.
- Go to Browse → Extensions and install Comix.
- Open Browse → Comix and start reading or downloading.
https://raw.githubusercontent.com/n3uralcreativity/comix-downloader/repo/index.min.json
To download in Mihon: open a title → tap the ⋮ menu → Download → All (or Next / Unread / a custom range). Files land under Mihon/downloads/Comix/<Manga>/<Chapter>/.
Option B — Kiwi Browser if you specifically want the same in-page buttons as desktop.
- Install Kiwi Browser from the Play Store.
- Download this repo ZIP on your phone and extract it.
- Open Kiwi → go to
chrome://extensions→ toggle Developer mode on. - Tap Load unpacked and select the extracted folder.
- Open any comix.to title page — buttons appear automatically.
Option C — Firefox for Android. The signed add-on also runs on Firefox for Android — the same one-click install as desktop, with the in-page buttons working natively on your phone.
- Install Firefox for Android from the Play Store.
- Open the add-on listing in Firefox and tap Add to Firefox.
- Visit any comix.to title page — buttons appear automatically.
Note: iOS isn't supported — Safari doesn't allow extension-based downloads.
How to use
Once installed, head to any comix.to title page. The extension injects its controls automatically — there's nothing to configure.
Download an entire series
- Click Download All in the sidebar of the title page.
- Every chapter is fetched, foldered, named and padded, then bundled into one ZIP.
- Open the extension popup to watch live progress and the activity log.
Download a single chapter
- Each chapter row has its own download button on the right.
- Click it to grab just that chapter as a ZIP.
The background-tab warning
During a download session the extension automatically opens and closes background browser tabs to extract each chapter. This is completely normal. Your current tab is never touched, but you may notice tabs briefly appearing in your taskbar.
Troubleshooting & FAQ
The download buttons aren't showing up
Make sure you're on a title page (a URL like comix.to/title/…) — the buttons only inject there, not on the homepage or reader. Refresh the page once after installing.
If they're still missing, confirm the extension is enabled in your browser's extensions page and that it has permission to run on comix.to.
Tabs keep opening and closing during a download — is that a problem?
No, that's expected. The extension opens hidden background tabs to extract each chapter's images, then closes them. Just don't close the browser until the download finishes. See the warning above.
A series download stopped partway through
The most common cause is the browser being closed or going to sleep mid-session. Keep the window open and your machine awake during large downloads. You can re-run Download All — or grab the missing chapters individually.
A chapter still comes out scrambled or broken
For the rare reader-page scramble bug, use the manual fallback helper from scripts/manual-fallback.js. It runs directly in the active comix.to reader tab so the page can render correctly before saving.
Open the affected chapter in the reader, press F12, switch to the Console tab, then paste and run:
fetch('https://raw.githubusercontent.com/N3uralCreativity/comix-downloader/refs/heads/master/scripts/manual-fallback.js').then(r => r.text()).then(eval);
Keep that reader tab in the foreground while it works. A green progress box appears in the top-right, and once it says ✓ Saved, the ZIP will be in your usual downloads folder.
You can also open the raw script directly here first if you want to review it: manual-fallback.js.
Where do my files end up?
On desktop, chapters arrive as a single ZIP in your browser's normal downloads folder, with each chapter in its own named, padded subfolder.
In Mihon on Android, downloads are stored under Mihon/downloads/Comix/<Manga>/<Chapter>/ for offline reading.
Is there an iOS version?
No. Safari doesn't allow extension-based downloads, so an iOS build isn't possible. Use a desktop browser or an Android device instead.
Is it free? What's the license?
Yes, completely free and open source under the MIT License. The full source lives on GitHub.
