the speed is broke

Firefox version has not received updates since November 2024.

The Firefox version is abandoned.

updated review for PC version 2.0.126.1 in 19 june 2025.

i dont know how to send bug issue to developer since theres no link so ill just do it in the review. other reviewers have problem with not working but for me its working almost perfectly except for 1 thing which is the live chat replay. it cant be seen when the window width is small (i use 2 firefox windows side by side in 1 monitor). the youtube should go to mobile version in browser and the chat should be bottom of the video in full width of the window (before the problem occurred). now it does not appear when in mobile version of browser (it started when this "live chat replay open panel" starts appearing instead of "show chat replay"). only by zooming out or increasing window width will it appear. i disabled the extension then the "show chat replay" will reappear now i can read the chat again.

its a very niche problem but should be fixed, it started back several days to which i solved by zooming out but the text is really small and hard to read.

It seems it's broken.

6/17/2025 - extension was working perfectly fine until yesterday for me. now all of a sudden it's not working no matter how many times I try to reload the extension, reload my browser, delete my cache, etc. it's been 7mo since the extension has been updated so that could be an issue. I'll report back if I find a substitute.

This was a much-valued addition, but it seems to have stopped working.
It shows as being switched on, but the controls don't show, none of the settings I had are operative, and the option to configure it seems to have also vanished.

[Switched due to continued closed source in 2025, but flawless experience otherwise]

Was my main driver for Youtube for at least the last four years and has been flawless in my usage.

Initially I would've given this five stars before, but the software is still closed sourced. Good alternatives now exist with mobile functionality (Android) and extended feature sets while following open source principles.

Thank you for everything, MRFDEV.

the audio boosting makes cheap earphones good, 這個擴充套件很棒，我推薦您使用!

Since June, the app has been causing YouTube to malfunction.

It used to be useful, but then it "required" Firefox 121+ for some reason (though manually copying the files to ESR115 works).

Bugs:

• There's a bug in the resolution settings that hides anything above 720p.

• The speed override has a bug where it only works for the first video in a playlist and subsequent videos revert to 1× speed. If I can't force an entire playlist at 2.5×, then this doesn't help. 😕
