Is StreamSpeed safe?

Clean risk

StreamSpeed can disable Russian-language pages and play looping remote audio after its toolbar button is clicked.

When the toolbar button is clicked on matching .ru, .su, .by, or .xn--p1ai pages, StreamSpeed injects bundled scripts into the active tab. For Russian-language browsers, after a per-site three-day delay, the injected code disables page pointer events and appends looping audio loaded from a remote MP3 URL.
