StayFocusd – ウェブサイトブロッカー&フォーカスタイマー
Description from store

時間を浪費するウェブサイトに費やす時間を制限することで、生産性を高めましょう。

コンピュータの前に座り、生産性を上げると誓う。気がつけば12時間後。あなたはEメールをチェックし、Facebookのステータスを更新し、Redditを200ページ読み、Twitterフィードのすべての記事を読み、Wikipediaで好きなバンドを調べ、自分自身を虚栄心でググり、元彼をサイバーストーカーし、高校時代の片思いの相手のInstagramフィードをすべて閲覧し、オンラインポーカーで1週間分の給料を失った。

そして、オンラインポーカーで1週間分の給料を失った。

Long time user of this extension, I recently discoverd that since it was aquired it is scanning your traffic for god knows what. The embedded asset `youtube_hulu_vue.js` scans your traffic on site and reports back to mothership. An AI analysis of this codeblurb: This JavaScript file is a minified/bundled ad tracking and capture script designed to detect, extract, and report advertisements from streaming and social media platforms. Here's what it does: Purpose: This appears to be an ad intelligence/measurement tool - likely used for competitive analysis, brand safety monitoring, or ad verification. It's designed to run as a browser extension or injected script. Core Functionality Ad Detection Across Multiple Platforms: YouTube - Captures video ad data, ad IDs, and click-through URLs Hulu - Intercepts VAST/DASH manifest files to extract ad metadata Netflix - Monitors for pause-screen ads and video ad insertions TikTok - Captures sponsored content from the feed Twitter/X - Detects promoted tweets and extracts advertiser info VAST Ads - Parses VAST XML format used by many video ad systems Data Collection: Extracts ad dimensions, duration, source URLs, click-through links Computes MD5 hashes of ad content for deduplication Captures screenshots/canvas data from display ads Tracks advertiser IDs, brand names, and creative IDs Network Interception: Monkey-patches XMLHttpRequest.send() and fetch() to intercept API responses Monitors for playlist, manifest, and GraphQL responses containing ad data Cross-Frame Communication: Uses postMessage to communicate between iframes and parent windows Handles ads embedded in nested iframes Reporting: Bundles collected ad data into X (crawl data) objects Sends data via a sendData callback to an external collector Includes install IDs and crawl timestamps Key Classes b - Ad data model (dimensions, hash, URLs, platform-specific data) y - Source URL tracker (images, videos, iframes) X - Crawl session data container

Beyond W extension

Love this extension. It has quite literally changed my life. However, it has started to interfere with other sites that shouldn't be blocked. I think this happens when I move to another tab while the "Shouldn't you be working?" page loads. Recently (i.e. in the past few weeks), the loading of this page has been *incredibly* slow, particularly with loading the usage graph (e.g. 20-30 seconds minimum). I find that until the graph loads, I can't use any other tab or otherwise they will also get accidentally blocked. Once the graph loads, I can hit back on whatever tab was previously blocked and it's no longer an issue.

The plugin has a bug. When the timeout reaches it displays a message on the same page, but than if you switch to another page, a lot of times you would see that message on the other page. Not only that, it will be impossible to go back to the original page. A lot of times, this will happen again and again and again on different pages not even related to the original website which supposed to be blocked.

The extension is forcing you to grant it permissions to collect some data, even if you don't want to.

Amazing extension for boosting productivity and limiting your daily usage. this became part of my life and I can't surf the web without it so W for the developers. Only problwm is that with the new version of stayfree is kinda better and more polished so idk. I am using both rn

love the self-doubt it creates when you are cheating by trying to switch off the website!

The December 21st 2025 update has a glitch that causes me to not add any websites to the blocklist. The "add list" option doesn't work. I deleted and reinstalled the extension and the same problem came up. I then turned off a bunch of extensions and nothing changed. Chrome's updated to the newest version as I write this, so I dunno what to do. I may have to use another extension, which sucks as I've been consistently using this since late 2020.

Such a nice extension to stop yourself from roaming around websites and focus on your work ...also i really like the warning part where i was changing settings of my blocked websites and it was like "are u sure u wanna do this??" also "i'm telling your mom" ...i kinda like the warnings ..it's a fun to use this extension

This is just doing WAY too much. I hate it. And it just redirects you to a tab with a snarky comment saying "Shouldn't you be working?" thereby NEGATING THE WHOLE POINT of avoiding distractions. There is no way to disable this. This plugin SUCKS.

Greate extension, but when the time usage is exceed it should block sites from group, not all site (included working site)

Stay Focus is an incredible productivity tool that has truly transformed the way I work. The interface is clean and user-friendly, making it easy to organize tasks and stay on track throughout the day. I love the feature that allows me to set specific time limits for each task, helping me avoid distractions and work more efficiently. The notifications are gentle yet effective in reminding me to stay focused. Thanks to Stay Focus, I have seen a significant improvement in my productivity levels. I highly recommend this app to anyone looking to boost their focus and productivity.

Blocks nothing. Opens blocked sites left right and center and when I add them to the blocked list it says that i have already done that. So they should be blocked. But I am looking at an openend blocked site now and that one has also overlayed the site i was working on and now i can't get back to that site anymore. This extention is totally useless because this keeps happening.

Great app, almost impossible to disable.

When it is working, it is great... but it seems to break every month or two, and it has to be reinstalled. I don't know if it doesn't keep up with Chrome updates or what but it's frustrating to have to reinstall it regularly.
