Find the message or situation below. For your first download, start with Quick Start.

The chapter list won't load

1. Check that you're on a supported page. Most sites need the series or book page; Shonen Jump+ (少年ジャンプ＋) uses an episode page.
2. Check Options → Site Integrations to make sure the site is enabled. MangaDex also needs you to accept Chrome's site-access request and save the change.
3. If the panel shows Couldn't load this series, click Retry series.

If the problem remains, open the page normally and check whether the site itself is available. Chapter access can also depend on your account or region.

What do the save results mean?

Result	Meaning
Saved	Tako received confirmation that Chrome finished saving the required files
Saved to folder	All required files were saved to the selected folder
Previously processed	A record of earlier processing exists, but final saving was not confirmed
Failed / Partial	The task ended before all requested output was saved; check the task's error and chapter results
Skipped	That chapter was not processed, for example after cancellation or a folder-save failure

Saved records the result at the time of saving. Check Chrome Downloads or the task’s folder for its current location; files may have been moved or deleted afterward.

Tako is waiting for Chrome Downloads

Open Chrome Downloads and look for a paused transfer or a save dialog that needs your response. Tako waits for Chrome's final result before marking the chapter saved.

If Tako says saving could not be confirmed, check Chrome Downloads and your save folder before retrying. A file may already exist. The retry or restart action warns that it may create duplicates.

Folder access was lost

1. Find the failed task in the Side Panel or Options → Activity & History.
2. Open its folder actions and choose Grant access again.
3. After access is restored, choose Retry failed chapters or Restart task.

Granting access restores permission for that task’s original folder.

If its original destination is unavailable, choose a folder in Options → Storage & Files, click Save Changes, and create a new task. Existing tasks keep their original save location.

A download failed or saved only some files

Tako retries download failures according to your retry settings. If a task still fails, check the reported error before trying again.

• Retry failed chapters, when available, keeps completed chapters and tries failed, partially saved, and eligible skipped chapters again. A partially saved chapter starts from the beginning.
• Restart task tries every chapter again.

Both actions keep the task's filenames and save location. Existing files are handled using the task's file-conflict setting, so review partial output before retrying.

A folder-save error ends the task and skips the remaining chapters. Already saved files stay on disk. The optional Use Chrome Downloads if the folder is unavailable setting must be enabled before creating a task; it can switch destinations only before that task first attempts to write to its folder.

Work was interrupted by a browser restart

Tako restores queue and history records when it starts and checks work that may still be running. After a full browser restart, unfinished images and archives need to be downloaded again. Use Retry failed chapters for unfinished chapters or Restart task to try the full selection again.

If saving is unconfirmed, check for existing files first to avoid duplicates.

Canceling didn't stop a Chrome transfer

Canceling a task stops Tako's remaining processing and future chapters. Downloads Chrome has already accepted continue. Pause or cancel those transfers in Chrome Downloads. Files already saved remain on disk.

Clear history without deleting files

In Options → Activity & History, use Clear task history to remove finished, failed, and canceled task records. Use Clear chapter history to remove chapter records for all series.

The controls work independently: clearing task history preserves chapter history, and both leave downloaded files on disk.

Report a problem

Open a bug report with your Tako version, Chrome version, site, a public series URL, the visible message, and the steps that led to it. Leave out account credentials and private download links.
