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.

This addon claims there are filter rules. There are no filter rules that I could see. Searching the menu for "filter" reveals nothing. At best, you can "block" channels and videos, a feature youtube already has.

Also, installing this caused all of my firefox tabs on youtube to stop responding, forcing me to close and reopen each.

It's weird to me how strongly they are marketing this addon, too, and the uninstall page vaguely tries to guilt trip you for removing the plugin. I realize this is recommended by mozilla, but it's tripping a lot of sus metrics for me, and I can't recommend it.

Edit: Further review of the developer's responses on low scoring reviews make me even more certain this isn't a good idea. 1) The developers respond to claims the plugin slows users' browser down with "nuh uh no it doesn't" and "yeah well why don't you measure the milliseconds with dev tools?", and 2) The devs claim that voting less than 5 stars is "voting against the project". Why does that matter? Why does your score on your open source, free project matter? It's almost like you're pushing for popularity on your plugin for some other reason. It's incredibly suspicious, and that type of language is couched in incredibly manipulative undertones. *Don't install this.* This thing is full of red flags.

cool addon but how do I block certain channel? I don't see any button to do that.

Can't make it block shorts or playables, which is all I want the extension to do. I have every option enabled to block shorts and they still appear on YouTube mobile in my browser. What am I doing wrong?

On Android versions Firefox The extension does not work

Very slow (even by youtube standards), whatever what the dev will say: sometimes takes almost a minute to load a youtube video, and often will fail to load the full page, with the comments.

Very buggy: again, often failing to load a page fully, the mini-player suddenly not appearing anymore when scrolling down, or among many others, the limiting to H.264 not working reliably (to be fair, it only reliably works with enhanced-h264ify, whichever main youtube extension I use). Even the menu is buggy: the search bar will always cover the link to go back in the menu (so one has to close that search bar again and again), and if used in the extension panel (as opposed to using it pinned), it won't even fit the window properly, lol!

Fortunately, I discovered a little used extension (Tweaks for youtube: only about 3k users, which is baffling), that is great where Improve youtube isn't at all. I tested them all, and that's the only one I'll keep.

was working for a period of time but in the last month any settings used would lag youtube; back button and pause taking forever.
removed extension and youtube stared working again, unfortunate as it was a good addition :/

Please add customize for short video.
