Mozilla has begun using a new method for identifying browser installations. Identifiers known as dltoken, unique to each download, are embedded in the builds distributed from the official website, which are provided in the form of exe files for the Windows platform. Consequently, performing multiple downloads of the installation archive for the same platform results in downloading files with different checksums, as the identifiers are directly added to the downloaded file. <\/p>\n

The effect is only noticeable when downloading exe files from a Windows environment. When attempting to download from a browser or command line in Linux, the exe files are always the same. Archives that are not in executable formats also remain unchanged. It is claimed that disabling the dltoken tracking can be done by turning off telemetry in the browser, but it is unclear how managing telemetry in Firefox will help during the initial installation and affect data substitution during file downloads (the issue also occurs when downloading from Google Chrome). server<\/a>, which takes place during the downloading of files from the website (the problem also occurs when downloading from Google Chrome). As a workaround to obtain Firefox installation files without identifiers, one can initiate the download directly from ftp.mozilla.org. <\/p>\n

The reason for embedding the dltoken identifier is said to be the desire to link first installations, existing telemetry, and Google Analytics identifiers with actual browser downloads. In particular, this makes it possible to assess the reasons for deviations in the number of downloads and installations, and to understand which installations were prompted by specific downloads (for example, it can be determined that one downloaded file was used to install multiple instances of the browser, explaining why an unusually high number of installations was recorded in one day that did not correspond with the number of downloads).
