Description from store
⏩ Skips (or fast-forwards) silent parts in videos in real time and completely automatically.
🌐 Supports YouTube, Coursera, Twitch, local files, and (almost) any other website.
Useful for watching 👨🏫 lectures,🔴 stream recordings (VODs), 🎙️ podcasts, webinars, 📞 call & audio recordings, and other unedited videos where the speakers spend a portion of time on things other than talking.
But even if the video is tightly packed, it can also save a bit of time, so it's generally fine to keep it always on.
🕵️🚫 Fully offline and local. Does not track you or send your data anywhere.
🔃 Easy to turn on and off, without having to reload the page (it's there to save time after all!).
⚙️ Has a lot of different settings, but generally you won't have to constantly tune them or touch them at all.
⌨️ Has a lot of handy shortcuts (hotkeys): control video playback and extension settings without using a mouse (or eyes).
🆓🍺 Completely free, both as in "freedom" and as in "free beer" (at least for now):

- (2025-04-22) Billy: а х**и нельзя сделать скорость 1.1? вот мне быстро 1.25 А вообще хорошо. Upd.: Thanks for the update! Now I can do 1.1! Yay!
- (2023-11-08) David Katsina: заикания
- (2023-08-30) Jason Walls: This is absolutely phenomenal, perfect for watching unscripted YouTube webshows that have lots of pauses. My favorite use for it is for watching Critical Role - it makes watching that show 10x better and can cut out a good 10% or more of boring silence at times. If I could give the creator one suggestion, it would be to add a whitelist feature with wildcard support, so that one could make this extension only work on certain YouTube playlist urls, for example. A blacklist feature would be nice too. Those would just be luxuries, as the hotkey to toggle the extension does work fine already (as long as I remember to hit it when I switch between videos I want to speed up and those I don't.)
- (2023-08-28) Timofey Danilevskiy: Идея - мое почтение. Немного допилить алгоритм чтоб не было заиканий звука и будет вообще пушка! Удачи в разработке!

- (2022-05-24) Luis DLC: Funciona pero en archivos locales a cada rato se pausa el video y reanuda automaticamente, lo pueden corregir eso.
- (2022-05-24) À: Cuando funciona es excelente, pero solo consigo usarlo en archivos locales. en Youtube y otros, no funciona :(
- (2022-05-21) Daniel L Moreno: Excelente
- (2022-05-17) Ömer GÜZEL: This is wonderful. working with local file is also great. However, I decrese one star because the voice is distorted when I gave a margin.
- (2022-05-11) Eugenio Borzone: good
- (2022-05-07) Антон М: Невероятно, что расширение так хорошо работает с потоковыми видео!

- (2021-12-25) Amin Soheyli: It saves me lots of disk space and time, Because it works in realtime!
- (2021-12-18) Mohammad Hadi Morakabi: very useful because you can play local videos on your computer with this extension and skip silent parts
- (2021-12-05) Emil Steiner: I only watch recorded lectures while using this plugin. it's better than the commercial solution by cary for that job because it changes the speed on the fly. no need to recut anything
- (2021-12-04) D K: Working as it suppose to be! No issues so far, working great with offline files. 5+
- (2021-08-20) Pradhyun: Dude everything works fine but please add feature to silent the audio instead of speeding it up.....speeding it up creates a disturbing noise pls tell a solution for that
- (2021-05-18) Troy Nall: people should consider donating to this developer. this is a wonderful tool.
- (2021-05-04) chinpokomon_: Thank you! It is awesome
- (2021-03-26) Supercalifragilistic expialidocious: Best extension I found recently. Thank you so much!!
- (2021-03-20) Felis Catus: awesome extension that I use it everyday
- (2021-03-12) will free: This extension is wonderful. Very well-developed. with cookie and interface. However, there is one issue. The sound will be distorted when speed up. It would be great if u can fix this issue.
- (2021-02-27) Denis Duchev: Saved me so much time in youtube and lectures. If you want control over how you watch you need this. Id even fast forwards ads, if you don't like using ad blocker. Only probem is that sometimes video and audio mismatch, if there is a lot of silenced parts, but a quick five second reverse can fix that
- (2020-12-16) Alireza Ebrahimi: i love very very much this extension very very powerful can forward backward video remove client part of video and very powerful for lms videos. I Loved it .... thanks.
- (2020-12-16) Cheung Tyrone: This a wonderful extension. I came across jumpcutter (from carykh) a while ago but that program is just too cumbersome which cannot process long videos efficiently and this on-the-fly version is way better. Seems that carykh has diviated from the original purpose of jumping through silence part and instead positions his project as a creative vlog editing tool. One sugguestion that I have for this extension is that I gess it's better to allow the user to set a pattern to match the websites that he wants to run jumpcutter on. I guess people can do this with some other extensions like NooBoss but I personally only uses this for local files, and I cannot disable the extension when I am not on that page because otherwise I just cannot access the page anymore.
- (2020-11-22) Susanne Moseid Bryhni: On normal videos it kinda has this glitchy sound effect when suddenly speeding up. ive tried messing with the setting but it still happens. Might have to go back to just playing all videos at double speed :/
- (2020-10-17) mark ifi: while "Skip Silence" by vantezzen is a good extension, this is better.
- (2020-08-26) Sampath Eaty: This is great for skipping past and speeding up lecture videos, especially when the lecturer hesitates a lot.
