Youtube keeps breaking it, but it's not the extension's fault. Still annoying, but works very well when it's fixed.

It's been quite comfortable to use. However, there are quite a few times when it fails to load videos initially and requires several reloads before starting. If it doesn't play, adding a feature like automatic reloading would make it even more comfortable.

Warning. After having issues with the player filed a bug report. I did this as I wanted to aid the developer with fixing issues with the player as it is a free addon. However after jumping through hoops to assist Andrew, I have come to the conclusion that he is very incompetent, and lacking. This does not bode well for FastStream.

It doesn't work with the addon Firefox Multi-Account Containers, the player loads underneath the default Youtube player.

So far so good, my only real complaint is that it doesn't work well with another extension: Sponsorblock

It's Worked on every site, and Increased video optimization and Browser player. Big Like

It works as advertised. The videos I've been trying to watch buffered endlessly, but not anymore.

Seems very fast. Needs an option to deactivate ALL KEYBOARDS and set the preload per file.

Fantastic and versatile extension!! I installed it mainly so I could continue watching videos while moving in/out of areas with slower wifi connection around my house. Not only has it worked perfectly for this purpose, it also offers an awesome array of accessibility features and customization options which anyone could benefit from. Highly recommend

Very good extension. Recommended

Kinda works...It will preload a video on youtube...I use firefox with win 10 desktop..problem is if you open a youtube video in new tab the extension is disabled....you need to physically enable extension button in order for the extension to engage/turn on...by this time the youtube player has already started..then once thats done and the extension takes over the audio keeps playing even when you pause video...could have been what I needed...will keep looking for another way to force buffer.
