what is a focus extension, and which kind actually helps?

a focus extension is a browser add-on that helps you stay on what you meant to do by changing how distracting sites behave. some stop the sites loading at all, some make you wait or answer a question first, and some make the sites duller so they stop holding your attention. they all live in the browser, right where the distracting sites are.

the three approaches are worth understanding separately, because they suit different people and different problems.

blocking: the site doesn’t load

the most familiar approach. you keep a list of sites, and during the hours you choose, or after a daily time limit, the browser refuses to open them. some tools go further, blocking whole categories, apps on the computer, or the entire internet apart from an allowlist, and some can lock a block so it can’t be lifted until it ends.

where it shines: a hard deadline, an exam, a day when there is nothing on those sites you need. a block removes the choice, and when you can’t be trusted with the choice, that’s exactly right.

where it struggles: most of us need some of those sites some of the time, for messages, a work account, a video a friend sent. each legitimate need is a reason to lift the block, and a lifted block has a way of staying lifted. there’s also a rebound effect: when the block ends, the pent-up urge arrives all at once.

friction: the site loads, but not instantly

instead of saying no, these tools make you wait. a countdown before the page appears, a breathing exercise, a question about what you came for, or a few seconds where the only big button leads back to what you were doing.

where it shines: habits that run on autopilot. much of distracted browsing isn’t a decision; your hands type the address while your mind is elsewhere. a pause hands the decision back to you, and often the answer is “actually, no”.

where it struggles: if you really are determined to go, you’ll wait out the pause. friction changes the default, not the outcome, which is its strength and its limit.

dulling: the site loads, but it’s less rewarding

a third approach changes the site itself. turning it gray, slowing its videos, hiding its recommendation feeds, making scrolling take more effort. the site stays usable for the thing you came for, but the parts designed to keep you there lose their grip.

where it shines: sites you can’t or don’t want to block, like Instagram for messages or YouTube for tutorials. dulling keeps the useful part and takes away the pull. our guide to grayscale extensions explains why something as simple as removing color makes such a difference.

where it struggles: on its own, you can get used to it. gray stops feeling strange after a while, so dulling works best combined with some friction.

choosing a focus extension

a few questions sort out which kind you need:

• do you ever need the site? if never, during work, block it. if sometimes, prefer friction and dulling, which leave a way in.
• is the problem starting, or stopping? if you open sites without meaning to, friction helps most. if you open them on purpose and can’t leave, dulling helps more.
• will you switch it off? be honest. a tool you disable on day three does nothing. the best one is the one you’ll still be running in a month.
• what does it need access to? check the permissions. a tool that only needs the sites you choose sees far less than one that reads every page you visit.
• does anyone else know? tools that bring in another person, a friend who hears if you slip, add a kind of motivation no setting can.

where dimmer fits

dimmer is a Chrome extension built on friction and dulling, with accountability on top. nothing is ever blocked. on the sites you choose, it puts a short pause before they open that grows each time you continue in a day, turns them gray from the first frame, hides their feeds and tucks their results away on Google. with pro it also slows their videos, makes scrolling sluggish and asks a short question every few minutes. a friend you choose can hear if you break the promise you set.

the free plan puts the pause in front of two sites and turns every site you dim gray, and dimmer only ever asks Chrome for access to the sites you add, one at a time. if a hard block is what you need, read when a blocker is the right call first. if Instagram is the site, how to make Instagram boring is a good place to start, and how to stop doomscrolling on a laptop covers the broader habit.
