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

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

i like this addon its a must to keep old laptop usefull

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.

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

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

It works as advertised. The videos I've been trying to watch buffered endlessly, but not anymore.

Seems very fast. Needs an option to deactivate ALL KEYBOARDS and set the preload per file.

Fantastic and versatile extension!! I installed it mainly so I could continue watching videos while moving in/out of areas with slower wifi connection around my house. Not only has it worked perfectly for this purpose, it also offers an awesome array of accessibility features and customization options which anyone could benefit from. Highly recommend
