Working good so far, has all the features I want. Thanks!

The performance is very bad and the developer doesn't seem to be willing to fix it. Furthermore some features are missing and the ones that do exist don't work reliable, probably because of the very bad performance.

This extension doesn’t perform as advertised! I’m not sure what people like about it or why it receives high reviews, but it fails to fulfill the primary purpose for which I downloaded it. I wanted it to remove “Shorts” from my search results and home page. While it does partially remove them from my home page, it does nothing to improve my search results. Regardless of which toggles I activate, every search is completely filled with “Shorts,” rendering this extension useless for my needs.

As of today Youtube changed the right side sidebar design. Now it has huge thumbnails. 3x less information density.

Unfortunately the only thing i can do within the addon is simply to hide the sidebar as none of the other settings like displaying only the titles etc no longer work. Likely due to code changes by YouTube.

Hope you get it working again in the coming weeks so i can go back to 10 suggested videos, instead of 3.

Loop not working on mobile view (m.youtube.com/.....)

It simply doesn't work for the mobile YouTube site, only the desktop site which is unfortunate

In general, a nice add-on.
But: It's not actually "light weight", it slows the browser down and sometime prevents videos from playing. Besides that it will kind of switch off Adblock Plus and uBlock Origin if "allow ads" is turned on.
I was only looking for an add-on that presets video quality and playback speed, this is kind of an overkill for that purpose.

basically has many many features. worth it

Hi. There's a problem when opening YouTube videos that have chat. When I enable the "Appearance, Sidebar, Live chat, Hidden" option in Improve YouTube, instead of hiding the chat, half the video remains with a black box. Previously, when I enabled this option, the chat disappeared completely, and the video didn't have half the screen with a black box.
Could you please resolve this issue?
Regards.

I use this add-on primarily for removing shorts from Youtube. It works perfectly and saves me from brainrot. Soon after Youtube added the AI descriptions, an absolute disgrace of a feature, this add-on added the option to remove them too. Amazing work!

I just want a button to reverse a playlist. It's great when it works, but most of the time it just does not show up even though it's absolutely checked in the settings (other stuff works fine, I can change the themes easily, but the entire playlist section just does nothing)

With this extension you still can't like or dislike a song on youtube music website with any other window in focus. It's 2025. Youtube music website is 10 years old and you still have to alt tab and manually point and click like/dislike button. Unbelievable.

Last version is BUGGY, very high cpu usage causes Youtube tab to crash. Fix it

I want to like this extension so badly. It seems so promising. It's free and made by volunteers and open source.

But I've been trying it off and on for months now, and during that time I've tried it on 4 different browsers and 3 different operating systems (two desktop, one mobile), and it's always broken in multiple ways, and it always absolutely murders Firefox's performance.

Yes, I tried disabling other youtube and adblock extensions. And I tried running Improve Youtube alone and in private mode, with no other extensions. No dice.

And no, my computer is not a potato (nor is my phone). And this is the only addon that's been causing me problems like this.

This extension is just extremely broken, all the time, always. It feels like a super early alpha release, not a finished addon.

You can report issues on github, but even *if* that leads to the issue getting fixed in a halfway timely manner, there are always additional issues occuring at the same time.

There's no predicting which options in the settings menu will work, or which will break even more things, and seemingly aaaaaaall of them tank the browser's performance.

I genuinely don't understand how this addon is getting good reviews. I can imagine it might become an incredible addon eventually, if the tsunami of problems is ever overcome, and I really hope it does, but for right now... Don't waste your time, like I did. There are alternatives to this addon that actually work, and reliably so.

I'd only recommend installing this addon if you're wanting to get involved in developing it, by way of a hobby project.

very high cpu usage now. wasnt a problem until a few days ago.

Could you add the following features:
1) **an option to save the various options selected.** So that we can easily import these chosen saved options back again whenever we want.

2) **Add a stop button** to stop the video at its very start. Sometimes it is useful to check again what was the original starting image of the video. Or when you want to repeat from the very start.

3) In the theater mode, there is an extremely annoying "More videos" option that appears and it is impossible to see below this "More videos" option the comments.
I could very well be a BUG.
Add **an option to get rid completely of this "More videos" option in this theater mode and replace it by allowing instead to be able to see the comments normally** instead of this very annoying "More videos" set of video links.
---Remark: Strangely, this problem seems specific to Firefox because it does not appear when using Microsoft Edge with this same addon improve youtube.

4) Below the description, there is now (sometimes but not always) a summary section that is created automatically. **Allow us to chose, for this summary section, the option expanded** like it is available also for the Description.

---One issue:
**Under the section Player, Pause while I watch a 2nd video.** It does not work if you watch a 2nd video that is a short video; in such a case, the first video will NOT pause while the second short video will keep running and the sound of the first video will interfere with the sound of the second short video!
It does not work even for any video that you watch first! Very annoying.
This is a serious BUG.

Thanks to the developer for this addon.

The extension offers a lot of useful features, but it severely affected my Firefox performance immediately after installation. The browser became noticeably slower, and C.P.U. usage spiked by ~35%. From what I’ve seen in other reviews, the developer tends to dismiss, and deny these performance issues rather than investigating, or assisting affected users; replying with responses in denial, instead of looking into the issue. Unfortunately, due to these problems and the lack of constructive support, I cannot recommend this extension.

It's works fine on PC but not on mobile. Blacklist does not work at all and even freezes the browser.

Abandoned by Enhancer (for YouTube) and, looking for a replacement, switched to this one. I hardly miss Enhancer at all. The only thing I really miss in the change of extension is the comments of youtube, sorted by most recent by default. It seems to me that this extension can't do that. Other than that, everything looks great.
