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?

The pre-downloading feature helped me a lot especially with my country that has a very slow internet speed. It is one of my necessary extensions now, highly recommend trying this extension.

I really love it and appreciate your work. Really makes watching videos online pleasure

This extension makes videos load significantly faster for me! Highly recommended!

This addon is amazing. Fast or slow internet, open a webpage with a video, press the button and you get the best video player with so many options. It is imperative to try with any streaming site, also great if you want to share your screen to a tv. Open Subtitle support is amazing, allowing me to watch Jackie Chan movies with actually good subs. Thank you!

I have a fast internet connection, but have regular buffering problems on various movie streaming sites (some sites worse than others), even in the latest Firefox 146. Tried all the about:config tweaks, disabling extensions, etc etc. but nothing worked. The problem was instantly resolved with this extension. It also instantly resolved a persistent audio sync problem, even in netflix. Lip sync is absolutely perfect now. Can't get it to work properly on youtube, or at least its buggy, and I couldn't be bothered figuring out why, because i never have problems streaming youtube videos, even at ridiculous speeds (I use youtube enhancer).
One recommendation: by default, fastStream is set to "predownload the entire video in the background if possible". I think this is overkill, the extension works so well, you can easily turn this option off, with this option off it preloads movies about 4-5 minutes ahead, which is more than enough.

I love this addon, it's truly cream of the crop. I have iffy internet, I love the peace of mind knowing that I will be able to finish a video if I experience an outage.

There are also many other features that I've gotten lots of use out of, and the customizable hotkeys have made it easy to use.

Does not work for youtube anymore, need for fix update!

Wow... I normally don't write reviews, but this addon blows my mind. I was already happy with the streaming boost it delivers on every streaming site. But then I pressed the audio button... What the hell, a completely free, working equalizer.... Damn this thing delivers!

Fantastic addon for when you have problematic Wi-Fi!

You can't watch the series yet, except for the first episode. I'm sorry my very bad English

Youtube keeps breaking it, but it's not the extension's fault. Still annoying, but works very well when it's fixed.

Warning. After having issues with the player filed a bug report. I did this as I wanted to aid the developer with fixing issues with the player as it is a free addon. However after jumping through hoops to assist Andrew, I have come to the conclusion that he is very incompetent, and lacking. This does not bode well for FastStream.

It doesn't work with the addon Firefox Multi-Account Containers, the player loads underneath the default Youtube player.

So far so good, my only real complaint is that it doesn't work well with another extension: Sponsorblock

It's Worked on every site, and Increased video optimization and Browser player. Big Like
