Chrome is powerful out of the box. It's also cluttered, tracker-riddled, and missing half the features you'd want for daily use. The good news: a well-chosen extension shelf turns Chrome into a much sharper tool without breaking anything.
We tested every popular extension category for 90 days across three machines. Here are the twelve worth installing this weekend — plus three we'd tell you to uninstall immediately.
1. uBlock Origin — the only ad-blocker you need
Free, open-source, blocks ads and trackers without selling your data to "acceptable ads" programs. Pages load faster, YouTube stops autoplaying, sponsored search results disappear.
If you install one extension from this list, install this. It's the single biggest performance and privacy upgrade you can make in five seconds.
Important note: in 2026, Chrome's Manifest V3 has restricted some ad-blockers. uBlock Origin Lite is the current version that works within the new rules. It's slightly less powerful than classic uBlock but still miles ahead of everything else.
2. Bitwarden — password autofill without the tears
If you followed our password managers guide, you're already using Bitwarden. The browser extension autofills logins, generates strong passwords, and syncs across every device.
Free forever for personal use. Installs in 30 seconds. Never memorise a password again.
3. Dark Reader — dark mode for the entire web
Every website, dark themed, automatically. Genuinely reduces eye strain during evening use, and the syntax highlighting for common sites (Gmail, GitHub, Google Docs) is impeccable.
Toggle per-site if a specific page breaks in dark mode. Set a schedule so it turns on at sunset. This is the extension our team gets asked about most often when someone sees our screens.
4. Bitwarden Send / Send Anywhere — no more email attachments
Both let you drop a file into your browser and get a temporary shareable link. No more "sorry, Gmail blocked my 25 MB attachment" or Dropbox account signups.
Bitwarden Send is bundled if you already pay Bitwarden Premium ($10/year). Send Anywhere is free with a device limit.
5. Grammarly (free tier) — catches embarrassing typos
The free tier catches spelling, obvious grammar mistakes, and awkward phrasings across every text field in Chrome — emails, forms, LinkedIn, everything. Skip the premium upsell; free is enough.
Alternative: LanguageTool is open-source, self-hostable if you're privacy-conscious, and comparable quality on the free tier.
6. OneTab — end tab hoarding forever
Click the OneTab icon → all your open tabs collapse into a single list you can restore later. Reduces memory usage by 90%+ during heavy browsing sessions.
Also useful for "I'll get back to this" tabs that would otherwise sit open for weeks slowing your machine down.
7. Save to Notion / Save to Obsidian — capture the article, not the tab
Whichever notes app you use, there's an official web-clipper. Instead of leaving 40 "read later" tabs open forever, one click saves the article, tagged and searchable, into your notes.
Alternative that plays nice with everything: Raindrop.io — free bookmarking with tags, screenshots, and search.
8. SponsorBlock for YouTube — skip the sponsor reads
Community-curated database of YouTube sponsor segments. Extension auto-skips them. Watch a 15-minute video in 12 minutes without hearing "and today's video is brought to you by..." for the thousandth time.
Categorised skips: sponsors, self-promotion, subscription reminders, outros. Toggle each independently.
9. Vimium — keyboard-navigate the web
For anyone who touch-types: Vimium lets you navigate the web without a mouse. Press f and every clickable link gets a two-letter shortcut. Press the letters, follow the link. Feels like a superpower after a week.
Steeper learning curve than the others on this list. Payoff is that mouse trips become optional.
10. StayFocusd — block time-wasters
Set daily time limits for specific sites (Reddit, Twitter/X, YouTube, whatever your poison). Once you hit the limit, the site is blocked for the rest of the day.
Won't solve willpower issues (you can uninstall the extension), but adds enough friction that most people cut their casual browsing by 40%+ in the first week.
Alternative: Freedom is subscription-based ($4/month) and syncs across all your devices, blocking apps too. Worth it if you're serious about focus.
11. Perplexity for Chrome — better answers from any page
Perplexity's browser extension gives you an "ask about this page" button — instant summary, follow-up questions, cited sources. Faster than switching tabs to Google or ChatGPT.
Free tier is generous. Pairs beautifully with the free tier of Claude for follow-up questions. See our 6 free AI tools guide for the full stack.
12. Privacy Badger — the second line of defence
From the EFF. Learns automatically which trackers follow you across sites and blocks them. Doesn't replace uBlock Origin — they cover different scopes and work well together.
Set-and-forget. No configuration needed. Genuinely makes the web less creepy.
The three extensions to uninstall right now
Any "coupon finder" extension (Honey, Coupert, etc.) — these hijack affiliate links, effectively stealing commissions from creators whose content you visited before shopping, and their coupon-finding is often no better than Google. They also have a long history of tracking every site you visit.
Any "PDF converter" or "screen recorder" from an unknown publisher — Chrome's extension store has a persistent problem with knock-offs that request excessive permissions. If it's not from a company you can name and verify, remove it.
Any "search suggest" or "shopping assistant" that got installed alongside another app — these are almost universally adware. Chrome's extensions page shows which are enabled; check quarterly and prune ruthlessly.
Rule of thumb: any browser extension you don't remember installing on purpose should be uninstalled today. Extension bloat is the single biggest cause of "Chrome feels slow" complaints we help with.
The 5-minute weekend setup
If you only do this once:
- Install uBlock Origin Lite — 30 seconds
- Install Bitwarden and import your passwords — 15 minutes
- Install Dark Reader — 30 seconds
- Install OneTab — 30 seconds
- Uninstall every extension you don't recognise — 5 minutes
Total under 25 minutes; permanent quality-of-life upgrade.
Frequently asked questions
Do extensions slow Chrome down?
A few well-written ones (uBlock Origin, Dark Reader, Bitwarden) actually make Chrome faster because they block resource-heavy trackers and ads. A dozen badly-written ones will drag the browser to a crawl. Audit quarterly.
Are these extensions safe?
Every extension in this list is either open-source or from a well-known company with a track record. The rule is simple: if the extension is free and asks for "read all your data on every website" permission, and it's not from a name you'd recognise, don't install it.
Do these work in Edge, Firefox, or Brave?
Most of them, yes — Chrome extensions install on Edge and Brave natively. Firefox has equivalent versions of everything on this list in its own store.
What about "AI browser sidebars" that promise to do everything?
Skip the paid ones (Sidekick, Arc's paid tier, Merlin AI). The free tier of Perplexity's extension plus Claude in a browser tab does 95% of what these promise, without a $10/month subscription.
Should I sync extensions across devices?
Chrome does this automatically if you sign into your Google account. It saves setup time but also means one compromised extension appears everywhere. If you value control, disable sync and install manually on each machine.
Still stuck?
Setting up a clean browser environment for a family member or non-technical colleague takes about 30 minutes. Book a session and we'll walk you through it live. From $29 flat.
How we tested these AI recommendations
Every AI tool and prompt in this guide was used in real work for at least 30 days by at least two members of the team — writing, coding, research, meeting summaries, spreadsheet work. Wherever we compared tools head-to-head (e.g., ChatGPT vs Claude for prose, Codeium vs Copilot for coding autocomplete), we ran the same prompts through both and had a third team member blind-rate the outputs.
AI is a fast-moving space and any specific tool comparison is a snapshot. We revisit these recommendations every 3-6 months and update where the ranking has genuinely changed. If you're reading this six months from publication, check the "Updated" date at the top — significant model releases may have shifted the recommendations.

Common AI questions we get
Which AI tool should I actually pay for?
For most people: none. The free tiers of Claude, ChatGPT, and Perplexity are enough. If you use AI daily for writing or coding, one paid subscription (Claude Pro at $20/month is our team's pick) covers most needs. Don't stack subscriptions.
Are AI tools safe to use for work data?
Depends on the tool. Consumer ChatGPT and Claude have modes that don't train on your data — enable them. For truly sensitive information (client contracts, PII), use the enterprise tier your company pays for or don't paste it in at all.
Will AI replace my job?
Probably not the whole job. Probably parts of your job that were already tedious. The people we see thriving are those who moved fastest to build AI into their workflow — not the ones waiting to see how it shakes out.
