User Reviews

曜日ごとの動画再生時間や、プラットフォーム横断で再生履歴が見られるのは面白いなと思う。
しかしニコ動とニコ生は対応が不完全らしくサムネイルが「No Image」となるほか、動画品質も測定されていませんでした。
YouTubeは動作してる模様。他は試していないので不明。

Is Web VideoMark Safe?
Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.
Web VideoMark requires a lot of sensitive permissions. Exercise caution before installing.

Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.
Web VideoMark is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
