Excellent Addon, still works, while quite a few others have stopped working over the time! :)

Only minor note: in the last days, it stopped hiding the video length on youtube feeds or channels - it did that before.

Great addon, i have only one small request if possible, on youtube i don't even want to see how much time as elapsed, as that can spoil too if you already have an expectation how long certain videos last due to past experience, but otherwise it's fantastic :3
