I'm a long time iOS app user and was delighted to find out that one sec also exists for Firefox. It works just as well! Maybe advertise it in the app, I didn't take it for granted that there would be a Firefox add-on.

Useful, it increased my productivity.

Works so well! Serves to dissuade you from going on distracting websites, but doesn't completely prevent you if you actually need to watch a quick youtube video or look at a reddit post, so you don't end up disabling it in annoyance.

Recommend the 1 second delay, perfect amount for me.

I stumbled upon this extension watching Ali Abdal video on time management. Despite its simplicity, it's a great extension. Just adds enough resistance to something you do automatically without any thinking. Which makes you think for a second "Do I really want to do this right now? or Is it just muscle memory and bad habits that brought me here?". Totally recommend for anyone struggling to decrease their usage for time wasting website and be more mindful on what you spend your time on. There's an app as well for those who don't know, available for both Android and iOS.

works great

Original review (4 stars). Not as fully featured as the iOS app, but still helpful

2024-05-06 update: Version 1.0.0 greatly improves the interface and brings it closer in feature parity to mobile! No complaints. 5 stars.

I absolutely hate this addon because it does its job. I recommend it!

Works as described and I've found it much more effective than simply blocking a website and it breaks the autopilot of visiting a site when distracted.
