mandalo.it
Send large files with Firefox
With the mandalo.it add-on you upload files from Firefox and get a download link with expiry, on EU infrastructure.
- Toolbar button for Firefox 140+
- Secure link on EU infrastructure
- Mandalo account: email + password (also if you use Google)
The problem we solve
Attaching large files in email or chat is awkward. From the mandalo.it button in Firefox you upload to the Italian service and copy a download link: the recipient downloads when they want, without bounced mail and without 10–25 MB limits.
Installation
The zip also includes ISTRUZIONI.txt. Firefox still requires loading it as a temporary add-on (not yet on addons.mozilla.org).
- Download the mandalo.it Firefox zip from the button on this page (or from Integrations in your account).
- In Firefox open about:debugging#/runtime/this-firefox
- Choose “This Firefox” → “Load Temporary Add-on…” and select the zip (or the unzipped manifest.json).
- Click the mandalo.it icon in the toolbar.
- Enter your Mandalo email and password → Sign in. If you only use Google, set a Mandalo password in Account first.
- Pick files, choose expiry, create the link and copy it wherever you need.
Download integrity
Verify the zip against the SHA-256 below. There is no addons.mozilla.org signature yet—this hash authenticates the file served by mandalo.it.
Package SHA-256
8453b839dc9f6db39a5fb961a429310b93fa1e67261314da54e85a0b9ba185d7
When the add-on is signed on addons.mozilla.org we will publish that signature too. Until then use SHA-256 + HTTPS from www.mandalo.it.
FAQ
Do I need a mandalo.it account?
Yes. You need a Mandalo password to create the API token. If you only use Google Login, set a password on the Account page first.
Does the add-on stay installed after restart?
As a temporary add-on, Firefox removes it on restart. That is expected until we publish on addons.mozilla.org.
Can I also use Thunderbird or Outlook?
Yes: there are dedicated Thunderbird (Filelink) and Outlook integrations. See those pages and Account → Integrations.
Where do the files go?
On mandalo.it servers (Italian operator, EU infrastructure), with expiry links like transfers from the website.
Is this a WeTransfer alternative for Firefox?
Yes: large files via link, Italian operator. See also the Italian alternative to WeTransfer page.
