Review summary

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.

2026-02-22	Fi*****	Well, I just came by so that i could say I do truly wish and hope it's a very fun, good, happy time of day/night. Plus, beyond with all of, my mind, heart, soul, and everything else of myself, I do really wish to see you happy. I'm so happy.with the addon/webapp . so im here to fully express and show my gratefulness to this web app and its dev who came up with it so we can possibly ever run. it in the first place i just love what is done all just for all the many of us who may need it from all the different nations will be using in in millions its much more than just good it's great,if I'm honest. i cant use a pc browser if i dont have it im sure it can run on firefox mobile and its different variants based on it which means it could get mozillas attention.and will probably add it on the list of few supported addons which its not few as most will run on firefox mobile and likewise apps your web is also unique as most users had wished for a web app just like it with the concept of replacing any built in native player of a site and especially on, YouTube. Since it has rules and laws,a nothing else can do all this non ever can replace a site's built in player and muchless if its youtube anything else just runs videos if its downloaded only by uploading it with a add on than run videos on a site directly but all i wish for is it if it could always be active always run unless or untill you ever turn it off im sure it has a filter list which lets you add sites you always want it running on but it is not dependable for me and try to make it not stutery if on youtube it must be a bad/too much latency thing if i can tell i think it only has stutering which is a problems but anything can be fixed with the power of a update and i prefer you naming it quick-stream so it can show respect to windows quicktime player a media/video file playing app from in the days

2026-02-11	Re*****	работает нормально, я понимаю, что это ранний доступ, но у меня есть несколько притензий. Качество видео не всегда можно поставить, даже если принудительно выстовить 1080р, всё равно видео может работать в качестве ниже. Я не понял как выбрать озвучку (аудиодорожку), или же ещё нет такого функционала. На некоторых сайтах расширение вообще не работает. И к предыдущему пункту скажу, что расширение не перехватывает плеер Kodik. Надеюсь, что в скором времени расширение станет ещё лучше

2026-01-18	Fi*****	Die Beschreibung ist missverständich, denn das Addon lässt das Buffern nicht weg - das würde alles nur deutlich verschlimmern. Stattdessen sorgt es nur dafür, dass der Buffer nicht erst 5-10s betragen muss, damit das Video fortgesetzt werden kann. Deshalb kommt es bei ausgelasteter Leitung seltener zu Rucklern. Man muss FastStream aktivieren und dann den passenden Stream auswählen, sonst wird womöglich eine zu hohe Qualität gewählt und es kommt mit dem Laden gar nicht hinterher... Es ist ein guter Video Player, allerdings wäre es schön, wenn man alle Stufen im Menü Videoqualität anzeigen würde, statt manchmal die verschiedenen Quellen wechseln zu müssen. Was mich allerdings am meisten stört, ist der Soundbereich. Wie deaktiviere ich die Audioeinstellungen komplett und nutze den Standard?
