  • (2021-04-08) Leep Loop: I feel like this would be pretty great if it actually worked. Doesn't matter what buttons I press or what number is displayed, the speed of the video remains unchanged.
  • (2021-04-08) Nash.: It's actually quite useful, it works with other websites too not just netflix which surprised me because i love to watch videos in 3x speed.
  • (2021-03-20) gaming 404: Do NOT Install this Chrome Extension - they use their extension to steal amazon link money from you
  • (2021-03-17) Grace Lasota: I love this app and it's ability to play up to 4x speed. One issue I haven't figured out yet is how to play one video at a normal speed on one tab and another video at a faster speed on a different tab. There is probably a way to do this I'm just not great at technology. Another issue I have is with videos with a built in speed feature and having this extension. The extension overrides the built in feature and it can get confusing when I don't realize I have it activated. TLDR: Overall a great extension, but not the most user friendly when trying to play multiple videos at once or videos with a built in speed function.
  • (2021-02-02) Create Great Life: Currently it is ok but I like Global Speed extension a lot because it has options like 2.5, 2.75 and higher speed also. There are buttons which increase and decrease speed like .1 and there are keyboard shortcuts also. Please add more features, currently that is making playback issues so I tried 10 others but these is the closest and best so looking forward for improvement.
  • (2021-01-08) Astrid Dewever: I've been using it for over 2 years and it works wonderful. I never had any complaints about it. Many friends of me use it now too.. Great extension, I recommend. Thanks!
  • (2020-12-30) Chetan Kumar: Works great, only wish the speed could be set for each site separately instead of a global setting. I watch everything at atleast 1.25x, but music sounds odd at that speed so have to change it back on any music streaming site.
  • (2020-12-20) Matheus Vitor: Em alguns sites a extensão está fazendo com que os vídeos iniciem várias reproduções sobrepondo a atual. Isso acontece se eu apenas deixar no 1.0x. Espero que corrija esse bug, porque faz até travar meu computador.
  • (2020-12-12) msm noor: good
  • (2020-12-02) baptiste boisset: Je viens de remarquer que cette extension modifiait les liens affilié sur Amazon, volant ainsi les distributeurs de contenu. De plus ceci est fait à votre insu
  • (2020-12-01) ziv kenet: Still app works great! Feedback: Keyboard shortcuts like cntrl-+ or <> would be very useful in full screen mode...
  • (2020-12-01) Teamo Eien Taiwan: Been using this extension for around 9 months now and i will say its easily the best helpful speedup extension. I like that it can go up to 4x instead of just 2x like many others which is a huge time saver especially for breezing through my online recorded lectures where some lecturer speaks slowly that even on 3x sounds normal. Been using 3x alot and did not notice any choppy issues like some stated. Might be because of their CPU/GPU/Hardisk configuration. I have a decent laptop (i5-8250u 8gb) and it works like a charm so should work perfectly on many devices out there except for very old devices
  • (2020-11-03) Can Gürdal: This is the useful thing ever. I'm watching everything in x2. I wish I can live x2. Thanx man for extension.
  • (2020-11-01) Anuk Arzum: Working well so far on Netflix, thanks for the extension!
  • (2020-10-30) Fabio Scafa: I've a question for developers, did you try to speedup netflix with a 5.1 audio track? It will reproduce bad audio, if I use stereo, all ok. Can you check ? :) thanks
  • (2020-10-22) Sofia Ouslis: Was amazing till it stopped working after a couple weeks, please try to fix this!!
  • (2020-10-16) sait yılmaz: en iyisi bu.
  • (2020-10-15) Rohan Panchal: A very good one. Worked for my player.
  • (2020-10-11) Forrest Behr: OMG, this is the most essential extension I've ever downloaded. Are you the "MTV generation"? --do you get stuff at twice the speed most people do? Then why watch videos at "slow people" speeds. I love 1.25, but often go to 1.5. There's just a certain freedom to intake media at your speed instead of the speed that some jerk editor, producer, or director decided they needed to spoon feed you at.
  • (2020-10-06) Griffin Betz: anoying pointless Online traing video.... Skipled love it, love everything about it
  • (2020-10-02) LD KonNick: the best choice !!!
  • (2020-09-25) Surya Duerre: works great but if you adjust speed inside video, it does not overwrite extension speed. second issue is that livestreams are also attempted to fast forward. i spend so long wondering what issue i was having till i realise the extension was attempting to fast forward my livestream too.
  • (2020-09-07) DOGGO MODE: I like it i can watch my shows faster now, it works on hulu too
  • (2020-08-21) Jahcica: It worked great for awhile but recently everything I've 2x has been really choppy. The audio is fine but the video just sort of skips frames very frequently. Maybe this is a problem on my end but just wanted to note it anyway in case it isn't.
  • (2020-08-20) Joanna: would've loved it if it had an option to not work on certain sites.
  • (2020-08-12) Vermithrax Omega: Excellent! Other speedup extensions don't work on prime video or netflix, but this works on all sites along with other sites like youtube in which other extensions work!
  • (2020-07-23) Just Some Guy Who Wants Your Bells: Replaces Amazon affiliate links with their own (which is against Amazon ToS) and also needs to read my browser history for some reason? Overall a pretty scummy way to steal affiliate links for money.
  • (2020-07-02) Hiz Hatt: Worked on Netflix Exactly what I need :D Thanks!
  • (2020-06-29) Maarten Labeeuw: App does what it says it does, so that’s a plus. A few questions/suggestions however: • Why does it need permission to “Read the browsing history”? • Why does it overrule speed settings in YouTube, even when site access for YouTube has not been explicitly allowed? • Keyboard shortcuts would be a nice bonus.
  • (2020-06-26) ⑤海牛丸: useful so happy i can finally speed up vids in netflix
  • (2020-06-23) RIPO HOMES International Turkey: Nice! I have been looking for this!
  • (2020-04-15) Greg Larsen: Very poor, no hotkeys and difficult to adjust speed. I don't recommend.
  • (2020-04-12) kingman ability: ممتاز
  • (2020-04-04) Edelyn Chiew: Works absolutely perfectly and is super easy to use!
  • (2020-03-23) Nelson Paarsmarkt: got this after the last extension had virus issues or something and this does the same job perfectly.
  • (2020-03-04) John Davis: He's stealing Amazon money!
  • (2020-03-03) Aberwock Leader: SpeedUp is a clone of my open source extension, but with an Amazon link hijacker. For proof, you can use an online CRX viewer to inspect their source code. The offending file is "content.js". My extension is available below. https://github.com/polywock/globalSpeed
  • (2020-01-30) Cedrsan cedrsan: Cette extension profite de votre ignorance pour ajouter un Tag d'affiliation chaque fois que vous visitez Amazon, et récupère une commission sur vos achats. En soi ça ne serait pas grave si c'était indiqué dans la description. Ici c'est fait a votre insu ! Désinstallée !!! This extension takes advantage of your ignorance to add an Affiliate Tag each time you visit Amazon, and earns a commission on your purchases. In itself it wouldn't matter if it was stated in the description. Here it is done without your knowledge! Uninstalled !!
  • (2019-11-05) seema subedi: This is for me !! Time saver when you wanna watch videos on amazon prime and other sites !!
  • (2019-06-17) Stephen K: why does an extension for video playback speed need my browsing history and location information?? Data merchants. Don't download!!
  • (2019-05-08) Disha Kukreja: Awesome extension! Works on all sites and is super easy to use. Would definitely recommend using this.
  • (2019-05-01) Sarneet Singh: This is a godsend when watching anime. Super helpful when watching videos on netflix and prime video
