- (2025-03-03) Exile Falcon kişiyim Chocobo NipponYume kurucusuyum: It is the extension that saved my life, because it can speed up everything including HTML5 videos. It saved my life while I was watching the question videos and solutions for university preparation. I AM ENDLESSLY THANKFUL TO YOU!!!
- (2024-11-05) Gordon Qian: awesome app that works well, even can go 5x speed for ads that are built into the videos
- (2024-11-03) Florian Djo.: fixed thanks
- (2024-10-13) TORLEY: SpeedUp doesn't work anymore with Chrome due to Manifest V3, enjoyed it a lot when it did. Hope it'll eventually be updated, but in the meantime, what's a worthwhile replacement for it?
- (2024-09-25) Akash: good but some time it CRASH
- (2024-08-22) J S: Works well. Alternatively you can use Trim. Then you can use keyboard to adjust playback speed on Netflix, PrimeVideo, Disney+, etc.
- (2024-08-02) Leah Garrison: awesome, works on netflix
- (2024-07-30) Charles Rosenberg: I love this extension. It's really great. I guess if I had to request one change it would be that I think it would be helpful if the slider at top moved to match any selection you might make below. It would make fine tuning the speed selection a little more intuitive. For instance, if you choose 2.25x at the bottom, it would be nice if the slider at top moved to the 2.25x position, so if you need to make it slightly faster or slightly slower with the slider, it would require less fiddling on the user's part. UPDATE: YOUTUBE SHORTS NOW ALWAYS CRASH WHEN YOU ARE HALFWAY THROUGH PLAYING THEM.

- (2024-01-01) Dropicz: works great for most services, but if you set it up its automatically applied for every website. you cant put a livestream on the left screen with normal speed and a video on the right screen with x2 for example. would be cool if you could set the speed separately for tab/domain/all amazon video player does not work

- (2023-05-18) Rehan Jinta: Amazing extension, works as intended. One suggestion tho, it will be a lot cooler if you added shortcuts because sometimes I need to quickly change the speed. Thnx!

- (2022-10-19) Fallaurac Live: This extension is super helpful and I love it works on a majority of websites but sometimes doesn't work with specific video players on certain websites. A feature someone else mentioned a long time ago that I've also thought would greatly improve this is the ability to block it from changing the speed on certain websites/pages sometimes I'll be watching a livestream at the same time as watching a sped up video for a homework assignment and then the livestream bugs out because its being played fast.

- (2022-08-08) Jorge Octavio Guzmán Sánchez: I LOVE IT BUT IT HASN'T THE BUTTON FOR 3x, 4x, etc. if i wana speed a video more than 2.25 then I need to guess en the slider the value and I waste time.

- (2022-07-06) Yan Sim: Great app! Curious if it's on the roadmap for the following: 1) Be able to choose/change the default speed buttons - I sometimes use 3X or 5X to breeze through instructional videos to find a spot in the video but it takes extra clicks to get to above 2.25X 2) Have a keyboard shortcut to quickly change speeds - Youtube has a shortcut and that's super helpful to quickly adjust speeds without clicking above to the extension Thanks!

- (2022-04-26) Matt Philie: I like it! I'd give it 5 stars if I could block it on certain websites. Example: I view my security camera from Nest but it's speeding it up because I'm watching something on another site at 2x. Same with Tweetdeck, speeding up GIFs and such. If I could simply block it from accessing certain domains, it'd be 100x better.

- (2022-02-18) Aaron Bell: Wonderful app. Would be 5 stars if I could set 1x for some sites/tabs (for music) and a different speed for other stuff. Why listen to both at once? 1) I don't; while the extension is set at 2x, it'd just prevent the music videos from starting out at 2x speed; or 2) if I did, the music'd be quiet background noise for a more "boring" speaker. Thanks for making this app.
