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

This extension is pretty buggy and has some bizarre delays. "Force Theater Mode" takes 1 second to activate, I sometimes start moving my mouse to the theater button and then it suddenly activates it. Could've done it myself if it takes this long. Same thing happens with "Shorts: Force to use the standard player", it plays the video for 5 seconds and then reloads the page to the standard player, starting the video from 0:00 again. "Pause while I watch a 2nd video" only works sometimes. Most of the time I have to switch tabs and pause myself. Tried this extension out because it's at the top right now but I got annoyed enough to uninstall and rate it. And no mr. developer, I will not file bug reports for this.

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).

YouTube Tab keps lagging. Not usable

This extension works but seems to make the site laggy

Great replacement for the defunct "Enhancer for YouTube" extension

Is this extension now working or still hanging whole YT?

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.

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.
