User Reviews

User reviews praise faster loading, reduced buffering, reliable preloading, and strong subtitle and audio controls across many sites. Recurrent drawbacks focus on YouTube compatibility, conflicts with some extensions, and inconsistent quality selection on certain sites.

Pros

Significantly faster loading and reduced buffering across many streaming sites, even on slower connections.
Pre-download/preload features improve reliability and smooth playback during outages.
Robust subtitle support with customizable options, including anime sites and foreign-language videos.
Integrated audio controls and an equalizer provide better sound quality and lip-sync.
Works across a wide range of sites, delivering a generally smoother playback experience.

Cons

YouTube compatibility issues: the extension does not work well with YouTube and can break there.
Conflicts with other extensions (e.g., Firefox Multi-Account Containers and SponsorBlock) causing the player to fail or load behind the site.
Quality/stream selection can be confusing or insufficient: not all quality levels are shown and auto-selection can pick too high a quality, leading to loading problems.

Recent reviews

The app states i cant play videos that require YouTube Login. So what use is it? Uninstalling.

It WOULD not download the caption even though it could see it as I was able to use the CC button to enable it. Makes it a useless application.

Works as intended, even lets you customize subtitles on anime websites

Is FastStream Video Player 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.

FastStream Video Player 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.

FastStream Video Player may not be trust-worthy. Avoid installing if possible unless you really trust this publisher.
