Is TeraBox Download Assistant safe?

Low risk

TeraBox Download Assistant injects its extension ID into every page's DOM, allowing any website to detect that the extension is installed.

The extension's two content scripts run on all URLs and insert a hidden div element containing the extension's runtime ID into each page. This allows any website to read the element and confirm the extension's presence without any network request. The extension's primary function is to facilitate downloading files from TeraBox cloud storage.
