Is HTML5 Video Everywhere safe?

Low risk

HTML5 Video Everywhere reports supported-site injection counters to api.admin.tik.tn after version changes.

When its content scripts run on supported video sites, the extension stores per-module injection counters in local browser storage. After the extension version changes, it sends each module name, count, extension version, and a moz-extension URL for that module to api.admin.tik.tn unless Do Not Track is enabled.

Where it sends data

Destinations our analysis observed HTML5 Video Everywhere contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.

  • api.admin.tik.tn
