Works perfectly. Only request would be the addition of 1.75x speed option.
Works as described! I wonder why we can't control a BlackBoard recording to begin with honestly, this extension really helps me sit and focus through long lectures compared to when they were normal speed. I also enjoy how the extension has the same speed ranges as a YouTube video (0.25x - 2x) instead of just making videos faster, really helpful for when I need to slow down what my professors say.
