FileFast: File Transfer & Gmail door Primoz

FileFast turns the Firefox sidebar into a secure file-transfer workspace. Select multiple files or a folder, preserve folder paths, choose link or email delivery, set expiry and access, and follow combined upload progress without leaving your browser.

When the transfer is ready, copy one FileFast link or insert it into a visible Gmail draft. FileFast never presses Send and does not read your inbox or contacts.

Uploads use your FileFast account, plan limits, safety checks and resumable multipart transfer service. Interrupted multipart uploads can continue after you safely reselect the same local files.

The extension supports light and dark appearance. It stores only the signed-in session and short-lived resume checkpoints in restricted extension storage. Signing out clears both.
