Do Not Use. According to the developer, if you're experiencing a problem, NO YOU DIDN'T. Massive lag on whatever computer I run it on. And at this point, reading the developer responses, if they fixed it completely, I wouldn't touch the thing with a 10 foot pole. DO. NOT. USE. And do not support this developer.

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

Pretty outdated by 2026 (eg, Shorts still visible despite trying to hide them, Join buttons hide Improve YouTube options, generally pretty bloated with redundant optionality better covered by other apps or by YT updates enabling such options, etc.)

Unuseable.

Like some users after installing this extension the fan was overworked with noises. HOWEVER, on closer inspection the issue was likely caused by having the in extension adblocking feature turned on while another adblocker (e.g. uBO or Adguard) was already in use. Simply put, when it comes to - Youtube - adblocker, use either the one within this extension or uBO/AdGuard/Ghostery etc. but never both or more.

I wanted the comment section on the right side of the page next to the video and was able to get this done using this extension. Absolute slam dunk.

Caused widespread lag and high fan usage. Required uninstalling, multiple reboots, and a system restore to resolve.

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
