Description from store
Tired of having videos buffer with slow internet speeds? Frustrated by a website's lack of accessibility features? This extension will replace videos on websites with a video player designed for your needs. Say goodbye to buffering and hello to a more accessible video experience!
1. Automatic fragmentation and parallel requests for up to 6x faster download speeds. Watch videos without interruptions by predownloading the video in the background.
2. Advanced subtitling features include: customizable subtitle appearance, built-in OpenSubtitles support to find subtitles on the internet, and an intuitive subtitle syncing tool to adjust subtitle timings on the fly.
3. Adjustable audio dynamics (equalizer, compressor, mixer, mono, volume booster), and video settings (brightness, contrast, hue, LMS daltonization for color blindness) for your unique audiovisual preferences.
4. 20+ remappable keybinds and accessible tool buttons for easy control of the player.
5. Available in multiple languages! Translated into Spanish, Japanese, Russian, and Malay by the FastStream community. Support for more languages is coming soon!
The player currently supports:
- MP4 videos (.mp4)
- HLS streams (.m3u8)
- DASH streams (.mpd)
- Youtube (download not supported on Chrome unless manually installed due to Web Store policy)
To use the player, simply:
1. Go to any website you want with a video and toggle the extension on. Any video it detects will be automatically replaced with the FastStream player.
2. Alternatively, you can also simply click on or navigate to a stream manifest file (m3u8/mpd) to begin playing.
3. Navigate to a new tab and press the extension icon to go to the player. Play sources detected on other tabs through the Sources Browser. You can also drag and drop video files from your computer.
Notes:
- We do not officially support Brave, or other Chromium based browsers besides Chrome. Please keep in mind that not all features may be available on those platforms.
- Livestreams are not supported. They will not be supported in the near future.
- This player will not function with DRM protected content. This is intended. Please be mindful of how you use this tool. FastStream should not be used to infringe copyright.
- This player is still a work-in-progress. Please report any bugs to the Github issue tracker here: https://github.com/Andrews54757/FastStream/issues
- For your privacy, this extension does not collect telemetry. Nor does it require additional resources from the internet to function. It will work fully offline. Feel free to browse the codebase on Github.
- We take accessibility concerns seriously! If you need accommodations not available in the latest version, please contact us and we will work on it ASAP. Also, please feel free to submit feature requests or suggestions on the Github issue tracker!
- The default maximum size for pre-buffering is 5GB. This can be changed in the settings page. Please be mindful of your computer's storage space when changing this setting. Browsers will offload data in the RAM to the SSD if the video is too large. Frequently pre-buffering large videos can reduce the lifespan of your SSD.

- (2025-07-16) Denny Lenselink: This is an amazing extension. Videos used to be stuttering on my old hardware but now they play fluently. Thanks for your work. One thing though. I love the player to support Chromecast but it's not a big deal.
- (2025-07-10) Works on Twitch, now i can watch VOD's at 2.5x speed without it buffering every 2 seconds.
- (2025-07-10) FuckingRandomInternetShit “FuckingRandomInternetShit”: Works great!
- (2025-07-09) Maja Misak: very efficient and amazing addon, and helps with buffering but it stopped working on youtube for me in last few months. EDIT: my mistake I updated to latest version and it works now :)
- (2025-07-07) Garence Jones: nice
- (2025-06-30) CLINTON CANN: Doesn't play drm protected videos meaning i can't watch most streaming services on starlink.
- (2025-06-23) Yasink21: it's a great tool for improving efficiency with video streaming, I hope it'll get livestreaming features soon so that I can always use it on youtube, without having to start it manually.
- (2025-06-22) Frank Viggo Adsen: The best app i have found here. video buffering problems gone, if you have slow buffering whit this app its a server side problem. MAX score from me. Anime streaming have never been this good.
- (2025-06-16) Jarek Tyszkiewicz (NET/forceTECH.KEY): Something like this would be useful. connected to this player https://chromewebstore.google.com/detail/czytnik-napis%C3%B3w-youtube/nplkdkbfnfheognggghkckpgngbjkahe
- (2025-06-11) JOJI: ABSOLUTELY AMAZING, LOVE THE EXTENSION!!! PLS DON'T END THIS PROJECT EVER FR!
- (2025-06-11) Colton Burnette: The GOAT I wish you could zoom the video with keyboard shortcuts, though.
- (2025-06-11) Spooky Calla: the loop doesn't work properly, I always set it to skip intros and outros of music but it still plays them no matter how i set the time on the loop. Also it amplifies the bass to DEAFENING levels and I can't adjust that any way.
- (2025-06-09) Trader UMR: greatest of all
- (2025-06-07) Louis Polge: everything you need
- (2025-05-30) Martnie Viojan: hack foor slow pc
- (2025-05-29) radcowboy: I've been using this plugin for a long time, maybe a year now, but i just used it earlier and some buttons like the fullscreen and x buttons to close menus would open up external links/ads/shady websites unrelated to faststream (despite also having adblock on) which makes me believe at this current time the extension is unsafe and compromised. It was never like this before, so be wary when downloading this before its next update. I wouldve rated this 4 or 5 stars because this extension was my go-to for streaming videos because of its convenient and thoughtful features, but i can't give it the same rating anymore purely for this major issue that could put users at risk.
- (2025-05-28) The Batman: please solve the problem video is not playing and please improve ui design of video player.
- (2025-05-28) Kip Hackman: Love, love, love this extension. I do wish that the included skip back and forward 10s buttons used the custom keyboard keybind intervals, though. I do also wish that more of the popout menus had close buttons on them too. Sometimes I have to think for a second to figure out if I have to click the button again to close them, click outside of the menu to close them, or something else. Still, this extension is worth its weight in gold.
- (2025-05-28) Patrick Lancuba: It is extraordinarily effective and eliminates 99% of the buffer times. I am very impressed
- (2025-05-23) Rendy Swift: good!
- (2025-05-11) MrMadHatter TV: Sometimes the autoplay doesn't work on every site but i still give it 5 stars because i feel that's more of an interface issue. It can make websites with too low of a sound go to 300% which i love, and the download speeds are so much faster than normal websites download and it gets rid of lag especially on odd 3rd party streaming websites that are bogged down for obvious reasons.
- (2025-05-11) Halo: MyFav ❤️
- (2025-05-04) Ernest Gert: Great application, replaces slow-seeding video players on various sites easily and does a remarkable job at loading videos quickly.

- (2025-04-10) Nash Michael-Lohs: 100/10 ily dev
- (2025-04-10) Trung Le: Amazing extension. This is somehow too good to be true but it is.
- (2025-04-09) James Jones: Ridiculously good and feature rich for a free extension. It's so good that you may feel guilty taking advantage of a young developer who should probably be charging for this version as the premium version.
- (2025-04-07) NewFanboy 1: Tbh, wonderful extetnion, ive only used it on a few vids but stilll, Only thing is that if i reload my video it doesnt save the exact time of what it was at before, and subtitles, but other than those 2 things, beutiful, I can watch my media at higher quaility without having to Worry about buffering, Would be a 5/5 star thing if those 2 things hadnt been a problem, also it redowns if i reload the page, so it takes a lil time but not much
- (2025-03-29) Samson Wong: Amazing extension. Gave new life to my old computer which was struggling to stream Youtube. I can now play on higher resolution and much less noise than before!
- (2025-03-27) Martin Moncada: its almost perfect, it has a quota on downloading subtitles, why does it even has that?
- (2025-03-18) parv: great player but how to change the screen ratio

- (2025-03-04) Tiago Paim: Amazing. A big upgrade compared the lackluster vanilla youtube player for my use case
- (2025-03-01) Cody Conder: Thus far the product has performed excellently; Is there a way to better support the maintainer of this project? I didn't see any opportunities on Github in my limited cursory glance for a "buy me a coffee" or other similar methods for direct support.
- (2025-02-25) Eric Thomas 2: WOW!00

- (2025-02-16) Ahmad Shbeeb: great
