Basically unusable, as it slowed my browser nearly to a halt, especially when on Youtube.

Changing settings are slow.

On MOBILE doesn't work at all. No matter which of the options I toogled on or off. Firefox v152.

While watching videos on YouTube, playback occasionally stops on its own. I am aware that the website has a feature that stops playback after 15 minutes of inactivity, but this seems to be a different issue.

In addition, videos sometimes stop playing when I switch to another browser tab. In those cases, playback resumes as soon as I return to the YouTube tab. The behavior is somewhat similar to the YouTube mobile app, where playback may stop when the screen or app is switched.

Both issues tend to occur near the beginning of a video rather than throughout the entire playback session.

I did not experience these problems while the add-on was disabled, so I suspect there may be some compatibility issue between the add-on and a web service or browser feature.

Half of the options not working
For example auto scroll shorts

The settings will not be retained. Every new page load is unchanged even though the settings are listed as active.

While the features this addon provides are great, I am unable to use any of them because every time I attempt to install this extension, my computer becomes unusably laggy regardless of whether youtube is active or not. My computer gets so laggy that youtube videos are no longer able to play. Am not sure if this is an issue on my end or on the developer's end but this extension is completely unusable for me.

For the past few days, some YouTube pages in Firefox have been experiencing terrible page freezes. The built-in manager shows a load of 100% or even 200+%. When the add-on is disabled and the page is reopened, everything returns to normal.

Worked well until it started crashing both my Zen browser and my wife's Waterfox with memory exhaustion.

Does not shuffle playlists on Firefox mobile. This is the only extension I could find that claimed to do this, but I was very dissapointed when the option was enabled and the playlist continued in order.

Works fine for the most part, but completely removes the recorded live chat for ALL videos with no options to turn it back on.

Great to begin with, but if you start going through your subscriptions it will bog down and break. And it turns out that the developer doesn't understand that not everyone who installs the extension is not their personal bug report.

Add on makes youtube unusably laggy.

And yes developer this is what reviews are for. They're for leaving information for others about the experience of using the app. "Makes the website it's for unusably slow" is useful information for other users. This isn't a technical or bug support request. It's a review of the functionality of the app.

Too bad, the options are very relevant, but this extension makes YT unusable: depending on the chosen options, the YT window freezes. Calculation, settings, or others, we don't know what's happening. I don't quite understand the number of positive reviews, as I don't have such an exotic setup (FF 146.0.1 + YT Anti-Translate + Privacy Badger + Ublock Origin + Emoji CheatSet on W11x64).

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.

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

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.
