Top 10 'Context-Switch-Crushing' Chrome Extensions to install for reclaiming your deep work hours in 2025 - Goh Ling Yong
It's 2:00 PM. You're in the zone. The code is compiling, the words are flowing, the design is finally clicking into place. This is it—that glorious, elusive state of "deep work" where productivity soars. Then, a tiny red dot appears on a browser tab. A new email. You think, "I'll just take a quick peek." Thirty minutes later, you're 17 tabs deep into a rabbit hole about the history of sourdough starters, and the memory of your deep work session is a distant, taunting ghost.
This, my friends, is the devastating cost of context switching. Every time you shift your attention from one task to another, you pay a mental tax. Your brain has to unload the context of the first task and load up the context of the new one. It's inefficient, exhausting, and the single biggest saboteur of focused work in our digital age. The biggest culprit? The very tool we need to do our work: the web browser.
But what if we could transform our browser from a chaotic vortex of distraction into a fortified sanctuary for focus? We can. The key lies in being intentional and equipping ourselves with the right tools. As we look ahead to 2025, it's time to stop letting our tools dictate our attention. Here on the Goh Ling Yong blog, we're all about reclaiming control. These ten "context-switch-crushing" Chrome extensions are your new front line in the battle for deep work.
1. Toby for Tabs: The Workspace Commander
Tab overload is a classic symptom of a fractured workflow. You have 15 tabs for "Project Alpha," 12 for "Q4 Report Research," and another 8 for "Things to Read Later." Finding anything is a nightmare, and the visual clutter alone is enough to spike your cortisol levels. OneTab is great for saving memory, but Toby for Tabs is about saving your sanity.
Toby transforms your new tab page into a highly organized, visual dashboard for your work. You can group related tabs into "collections" and open an entire set of websites with a single click. Instead of juggling dozens of individual tabs, you manage cohesive workspaces. Finished with the Q4 report for the day? Close the entire collection. Time to switch to Project Alpha? Click to open its dedicated collection of links, documents, and resources.
This isn't just about closing tabs; it's about fundamentally changing how you switch between projects. The mental cost of context switching is dramatically reduced when you can load and unload an entire project's context instantly.
Pro-Tip: Create collections for your routines. Have a "Morning Kickstart" collection with your email, calendar, and project management tool. Have an "End of Day" collection with your time tracker and reporting dashboard. This automates the administrative parts of your day, preserving your best mental energy for the work that matters.
2. LeechBlock NG: The Uncompromising Gatekeeper
Willpower is a finite resource. Relying on it to avoid Twitter, Reddit, or news sites during a deep work session is a losing strategy. LeechBlock NG (Next Generation) is the digital equivalent of putting a deadbolt on the door to your biggest time sinks. It’s a free, open-source, and ridiculously powerful site blocker.
What makes LeechBlock NG so effective is its granular control. You can block sites entirely during specific hours (e.g., no social media from 9 AM to 5 PM). Or, you can set a time limit—allow yourself 10 minutes of "distraction" sites per day, and once the timer is up, they're locked. My favorite feature is the "delaying" option, which makes you wait a few seconds before a distracting site loads, giving your rational brain a moment to ask, "Do I really need to be here right now?"
By outsourcing your discipline to an extension, you eliminate the constant internal negotiation about whether you should or shouldn't check a site. This frees up an incredible amount of mental bandwidth, making it easier to stay locked into your primary task. It crushes the context switch before it even has a chance to happen.
Pro-Tip: Set up a "Lockdown" profile in LeechBlock NG. Configure it to block everything except a few whitelisted sites essential for your current task (e.g., Google Docs, a specific research site). When you start a deep work session, activate Lockdown. This is your nuclear option for guaranteed focus.
3. Pocket: The "Read It Later" Valet
You're researching a topic for work and stumble upon a fascinating article about a completely unrelated subject. The temptation to click and read is immense. If you give in, you've just triggered a context switch. If you resist, you're left with a nagging "open loop" in your brain, wondering what you're missing out on.
Pocket solves this dilemma beautifully. With a single click, you can save any article, video, or link to your personal, clutter-free reading list. The content is stripped of ads and distractions, and it syncs across all your devices. The psychological effect is profound: you've captured the interesting thing without derailing your current task. Your brain can relax, knowing the content is safe and sound for later.
Using Pocket religiously is like hiring a valet for your curiosity. You hand off interesting distractions to be dealt with at a more appropriate time—during your lunch break, on your commute, or in the evening. This simple habit keeps your primary work session clean and protects your focus from being hijacked by serendipitous discoveries.
Pro-Tip: Schedule a specific "Pocket Time" in your calendar once or twice a week. This dedicated time to go through your saved articles turns a potential source of distraction into a structured and enjoyable learning habit.
4. Notion Web Clipper: The Second Brain's Scribe
Ideas, insights, and important bits of information are everywhere. The problem is that capturing them often requires opening a new tab, finding your note-taking app, and breaking your flow. The Notion Web Clipper is an elegant solution that integrates directly with your existing "second brain" in Notion.
Whether you're saving an entire article for research, clipping a specific paragraph for inspiration, or snagging a screenshot of a design you like, this clipper makes it seamless. You can choose the exact Notion database and page where you want to save the content, and even add tags and properties right from the extension pop-up.
This dramatically lowers the friction of knowledge capture. You no longer have to choose between losing an idea and losing your focus. You capture the information into a trusted, organized system in seconds and immediately return to your task. It’s a critical tool for anyone who, like myself at Goh Ling Yong's agency, believes in building a robust personal knowledge management system.
Pro-Tip: Before starting a research-heavy project, create a dedicated database in Notion for it. Then, as you browse, use the clipper to send all relevant articles, code snippets, and resources directly to that database. You'll end up with a perfectly organized repository of information without ever having to manually copy and paste a thing.
5. Marinara: Pomodoro Assistant: The Timeboxing Coach
Deep work isn't about sprinting for eight hours straight; it's about managing your energy in focused bursts. The Pomodoro Technique—working in 25-minute focused intervals with 5-minute breaks—is a time-tested method for this. Marinara is the simplest, most unobtrusive Chrome extension for implementing it.
It lives as a tiny tomato icon in your toolbar. Click it, and a 25-minute timer starts. That's it. There are no fancy bells and whistles to distract you. It provides a subtle countdown, and a notification when it's time for a break. The psychological power of a visible timer is immense; it creates a sense of urgency and a clear finish line for your focus sprint.
Knowing you only have to maintain intense focus for a short, defined period makes the task less daunting. It also systemizes breaks, ensuring you step away to recharge before you burn out. This rhythmic cycle of focus and rest prevents the mental fatigue that leads to mindless browsing and costly context switches.
Pro-Tip: Use your short 5-minute breaks to do something completely non-digital. Stand up, stretch, grab a glass of water, or look out the window. This physical context switch helps your brain reset more effectively than switching to a different digital task.
6. uBlock Origin: The Serenity Filter
The modern web is visually LOUD. Auto-playing videos, flashing banner ads, pop-ups, and tracking scripts aren't just annoying; they're a direct assault on your attention. Each one is a potential micro-distraction, a tiny context switch that cumulatively drains your cognitive resources.
uBlock Origin is widely regarded as the best-in-class ad and tracker blocker. It's incredibly lightweight, so it won't slow your browser down, but it's ruthlessly effective at decluttering web pages. Visiting a site with uBlock Origin enabled after browsing without it is like stepping out of a noisy casino into a quiet library. The difference is palpable.
By filtering out this digital noise, uBlock Origin creates a calmer, more focused browsing environment. You can read articles and consume content without having to constantly dodge visual landmines. This preemptively eliminates a whole category of context switches you didn't even know you were making.
Pro-Tip: uBlock Origin can do more than just block ads. Use its "element picker" mode to permanently hide annoying, non-ad elements on sites you visit frequently. You can hide "trending" sidebars, "related posts" widgets, or comment sections to create a truly bespoke, distraction-free version of your favorite sites.
7. Checker Plus for Gmail: The Inbox Sentry
Email is the original context-switching culprit. The urge to check your inbox is a powerful, conditioned reflex. But opening that Gmail tab is a trap; it pulls you into a world of other people's priorities. Checker Plus for Gmail allows you to manage your email without ever leaving your current tab.
This extension provides detailed notifications and allows you to read, reply to, archive, or delete emails directly from a pop-up window. You can get the gist of a new message without the full, distracting immersion of the Gmail interface. It gives you the power to triage your inbox on your own terms.
This is a game-changer. You can quickly deal with an urgent message and immediately get back to what you were doing. For non-urgent messages, you can simply mark them as read or archive them, clearing the notification without breaking your stride. You stay in control, processing email when it suits you, not when the red dot demands it.
Pro-Tip: Customize the notifications heavily. Turn off sound alerts and set the extension to only notify you for emails from specific people or those marked as important. This turns it from a reactive tool into a proactive filter for what truly needs your attention.
8. Video Speed Controller: The Time-Bender
From tutorials and webinars to meeting recordings, video is an essential part of modern work. However, most people speak much slower than we can comprehend. Sitting through a 60-minute recording to find the 5 minutes of information you need is a massive time sink and a huge drain on your momentum.
Video Speed Controller is a beautifully simple extension that gives you granular control over the playback speed of any HTML5 video. Using simple keyboard shortcuts, you can speed up, slow down, or rewind video content on the fly. Listening to a tutorial at 1.5x or 1.8x speed can save you an incredible amount of time without sacrificing comprehension.
By consuming necessary video content more efficiently, you can extract the information you need and get back to your deep work faster. It reduces the "time away" from your core task, minimizing the negative impact of the context switch required to watch the video in the first place.
Pro-Tip: Use the "S" and "D" keys by default to speed up and slow down playback by 0.1 increments. Find your personal "sweet spot" for comprehension—for many, it's between 1.5x and 2.0x. Use the "R" key to reset to normal speed for complex sections.
9. Momentum: The Intentional New Tab
What's the first thing you do when you have a fleeting, unfocused moment? You open a new tab. That blank page with a search bar is a gateway to distraction. Momentum replaces that void with a beautiful photo, an inspiring quote, and, most importantly, a single, clear question: "What is your main focus for today?"
Every time you reflexively open a new tab, you are gently reminded of your primary objective. This small but consistent prompt is incredibly powerful for re-centering your attention. It transforms a moment of potential distraction into a moment of intentional refocusing.
Instead of typing "reddit.com" into the search bar, you see your stated goal and are more likely to close the tab and get back to work. It helps you build the crucial meta-skill of awareness—noticing when you're about to get off track and consciously choosing to return to your priorities.
Pro-Tip: Be specific with your daily focus. Instead of "Work on project," write "Draft the first section of the Q4 report." A clear, actionable goal is much more effective at pulling your attention back than a vague one.
10. Clipboard History Pro: The Unsung Workflow Hero
Think about how often you copy and paste. You copy a name from an email, switch to a CRM, and paste it. You copy a line of code from a forum, switch back to your editor, and paste it. Each "switch" is a small context switch. If you need to copy multiple items, you're forced into a frustrating back-and-forth dance between tabs.
Clipboard History Pro gives your computer a memory. It saves a list of everything you've recently copied. When you need to paste something, you can use a keyboard shortcut to bring up a list of your recent clips and select the one you need. No more toggling between source and destination.
This might seem like a small optimization, but the cumulative effect is huge. It smooths out countless micro-frictions in your daily workflow. By eliminating the need for repetitive tab switching for simple data transfer, it helps you stay in the flow state of a single application or task for longer.
Pro-Tip: "Favorite" snippets of text you use all the time, like your email address, specific hex codes, or canned email responses. Clipboard History Pro will keep these at the top of your list, turning it into a powerful text expansion tool.
Your Browser, Your Fortress
Your browser doesn't have to be a battlefield for your attention. By being intentional and leveraging the right tools, you can transform it from your biggest source of distraction into your most powerful asset for focused work. These extensions aren't magic bullets, but they are powerful allies that help build better habits, reduce mental friction, and protect your most valuable resource: your time and attention.
Don't try to install all ten at once. Pick one or two this week that address your biggest pain points. Is it tab overload? Start with Toby. Is it the lure of social media? Install LeechBlock NG. Make the change, feel the difference, and start reclaiming those precious hours of deep work you've been losing.
