Is Thunder Download Support Pro safe?

Low risk

Thunder Download Support Pro sends the current page URL to Xunlei's stats server when remote stats are enabled.

Its all-sites content script reads the current page URL and sends an xl_stat message when the remote isStatGlobal flag is enabled. The background script adds the active tab URL and sends those values to stat.download.xunlei.com over cleartext HTTP; child frames can also request the page title, but no fixed external recipient is shown for that lower-severity path.
