The operation of the Firefox Send service was suspended in early July due to its involvement in the distribution of malware, the storage of components used in various attacks, and the transfer of data intercepted as a result of malware or compromised user systems. The work was planned to be restored after the implementation of the possibility of submitting complaints about the placement of problematic content and the creation of a rapid response service, but, ultimately, it was decided to completely close the service.
Recall that Firefox Send allowed you to upload a file to the storage on Mozilla servers, up to 1 GB in size in anonymous mode and 2.5 GB when creating a registered account. On the browser side, the file was encrypted and transferred to the server in encrypted form. After downloading the file, the user was provided with a link that was generated on the client side and included an identifier and a decryption key. Using the provided link, the recipient could download the file and decrypt it on their side. The sender had the opportunity to determine the number of downloads, after which the file was deleted from the Mozilla repository, as well as the lifetime of the file (from one hour to 7 days).
Firefox Notes evolved as an experiment to create new methods for synchronizing encrypted data. Users were asked mobile app for Android and addition for a desktop browser that allowed you to create notes while browsing the web, and work with a single database of notes from different devices. In November, the Android application and servers serving the service will be decommissioned. The browser add-on will remain available to existing users of the service and will include an option to export all notes to HTML format. For new installations, the add-on will no longer be available.
