The "seek bar" is the bar at the bottom of a video that progresses as you play the video, and that you can click on or drag to skip around. Why companies ever thought it was a good idea to get rid of this I don't know, but I find it infuriating, so I decided to add it back for myself and thought others might like it too.
ReelControl adds a progress bar and seeking capabilities to videos on Instagram, YouTube Shorts, and Facebook Reels.
I do sometimes enjoy watching short-form content and I've found that with this extension enabled I can be more mindful about it and get sucked in way less. I'm also on my phone less because I tend to favor the web versions of these platforms now.
