works great, so many populated presets already

Literal god-send. On Linux trying to get Windows .iso files for VM and because I'm on a desktop computer Microsoft in it's infinite need to control users does not allow the download of .iso files or even make it an option... unless you change the user-agent of course, then it's not a problem any longer. Saved me having to actually use my phone to do it again like last time. Nice work people!

Super ten jest switcher do przeglądarki: "Mozilia Firefox"

Perfect extension that does exactly what it's supposed to do and what I need it to do, which is make YT work with FF and UBO without grossly slowing down actions due to Google's anti-competitive tomfoolery.

Unsure why so many people rate it so low. I assume they can't follow simple instructions to set it up or just didn't restart browsers after installed.

Works like a charm. My very high end PC (to watch videos on Youtube anyway) was suffering on YouTube and my suffering only gotten worse over time because Google was trying Firefox users to switch to their browser. Noticeable difference right after installing the extension. Recommended to all.

Amazing, fixed a myriad of youtube playback issues using the developers guide.
