Most problems have a one-line fix. Start below — and if none of it helps, email us and a person will read it.
Troubleshooting
The toolbar doesn't appear in Gmail
Reload the Gmail tab. After installing or updating an extension, tabs that were already open are still running the old code and need a refresh.
If it still isn't there, check that the extension is enabled at
chrome://extensions, and that you are on
mail.google.com rather than the Google Workspace admin console or
the basic HTML view of Gmail, neither of which is supported.
Chrome says "Gmail Bulk Extractor started debugging this browser"
That banner is expected, and it is Chrome being transparent rather than a sign of
a problem. Chrome only exposes real PDF rendering through the DevTools Protocol,
so the extension needs the debugger permission to produce a PDF at
all. It uses it for a single printToPDF call on a background tab it
opened itself, and the banner clears as soon as the export finishes.
Nothing is being inspected, recorded, or sent anywhere. See the privacy policy for the full explanation.
A PDF export failed or produced an empty file
Try the same selection again — a background render can fail if the tab is closed or the machine sleeps mid-export.
If it fails consistently: make sure no other extension is using the debugger on the same tab (Chrome only allows one attachment at a time), and check that Chrome's download location is writable. Very large selections are best done in batches of twenty or thirty.
Some attachments didn't download
Inline images that are part of the message body are captured in the email content rather than saved as separate files. Attachments Gmail itself blocks — executables, for instance — cannot be retrieved by any extension.
If a normal file is missing, open that email directly and confirm the attachment still downloads through Gmail's own button, then let us know.
My files have odd or shortened names
File names are derived from each email's subject, with characters your operating
system forbids in file names removed and long names truncated. On Pro you can
set your own naming templates from the extension popup using
{date}, {sender}, {subject} and
{index}.
The extension stopped responding after an update
Reload the Gmail tab. When Chrome updates or reloads an extension, content scripts in already-open tabs are disconnected and report an "extension context invalidated" error until the page is refreshed.
Trials, Pro and billing
How does the trial work?
Every install starts with a full-featured 7-day Pro trial — no card and no account required. When it ends the extension carries on working on the Free tier: PDF and Attachments stay available up to 100 emails a week, while ZIP, Merge and custom naming become Pro features. Nothing you already exported is affected.
I paid, but the extension still shows Free
Open the extension popup and use Restore purchase, then sign in with the email address you paid with. Licences are tied to that address rather than to a particular machine, which is also how you move Pro to a new computer.
If it still shows Free after restoring, email us from the address you paid with and we will sort it out.
How do I cancel or change my subscription?
Open the extension popup and choose Manage subscription. That takes you to ExtensionPay, our payment provider, where you can update your card, switch plan, or cancel. Cancelling leaves Pro active until the end of the period you have already paid for.
Can I use Pro on more than one computer?
Yes. Install the extension on the other machine, open the popup, choose Restore purchase, and sign in with the same email address.
Refunds
If the extension doesn't do what this site says it does, email us within 30 days of purchase and we will refund you. Please tell us what went wrong — it is usually something we can fix.
