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).

This extension works but seems to make the site laggy

Great replacement for the defunct "Enhancer for YouTube" extension

Finally, an extension to block those pesky and pointless shorts and member only content that actually works. Thank you creators, you truly made YouTube usable again. Love all of the customization as well.

Finally something that just works and have what I want!

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.

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.
