Not the most intuitive addon out there but it works well.

прекрасная программа, очень помогает

Thank you for this extension I can now watch Youtube videos without wattling forever for the video player to show up. I use windows 11 home supported on my hp pavilion laptop 32gb of ram intel core I7 8gen Firefox nightly 12864bit.

It works. I use the whitelist mode for specific websites. The user interface throughout the extension could use some bells and whistles.

I don't know why there's so many people saying this doesn't work and I barely understand this thing, but I used this to make YouTube load faster. Spoofing as Chrome, the site loads in half the time than it would take without this extension. Unfortunately it does seem to break some captchas, like cloudflare, as in after pressing "I'm human" or whatever; it just loads and the the captcha gets refreshed, so it never proceeds to the site.

Thanks to the author.

It's really useful!
