These are the Chrome extensions I currently use. My favorite ones are boldfaced.

• Application Launcher for Drive. Open Drive files directly from your browser in compatible applications installed on your computer.
• Bitly. URL shortener.
• BuiltWith Technology Profiler. Find out what the website you are visiting is built with.
• Bypass Paywalls. See paywalled content from all the major media outlets (e.g. Financial Times, The Economist, etc.) as well as other sites.
• Browserpass. Browser extension for pass, the standard Unix password manager.
• CLUT: Cycle Last Used Tab. Toggle between your current and last used tab with a keyboard shortcut. I use this extension hundreds of times per day.
• Contact Out. Find a person’s email, as long as they have a LinkedIn account.
• Dark Reader. Dark mode for every website. My personal settings are here.
• Don’t add custom search engines. Prevent Chrome from auto-adding custom search engines.
• Get RSS Feed URL. Adds one-click subscription to Chrome’s toolbar.
• Ghost Text. In combination with Atomic Chrome, this extension lets me enter text (e.g. writing a comment or editing a Wikipedia article) directly from Emacs.
• Google Docs Offline.
• Grammarly. Spell checker and more.
• I still don’t care about cookies. Do you like clicking a consent button every damned time you visit a new website? Then why are you not using this extension? [Mostly relevant for EU residents.]
• Keyboard Shortcuts for Google Translate. Provides keyboard shortcuts on the Google Translate page.
• My IMDb. Highlights the movies you’ve already seen (voted for) when searching IMDb or displaying actor/director pages.
• Print Friendly & PDF. Improves the print version of a web page by removing ads and fixing broken layout.
• Return YouTube dislike. For inexplicable reasons, although YouTube still lets users dislike videos, it no longer displays the number of video dislikes. This extension restores the dislike count.
• ReviewMeta.com Review Analyzer. Adjusts Amazon’s ratings to exclude fake reviews.
• Shut up. “If you’ve ever gone to a website and read its comments section, you’ll have seen that it’s just a vitriolic, idiotic wasteland. Why subject yourself to that?”
• Tag Assistant. Helps troubleshoot installation of various Google tags including Google Analytics, Google Tag Manager and more.
• uBlacklist. Blocks specific sites from appearing in Google search results. My list of blocked sites is here.
• uBlock Origin. A fast, potent, and lean ad-blocker. I shared some customizations here.
• Unhook. Hides YouTube related videos, comments, shorts tab, suggestions wall, homepage recommendations, trending, and other distractions. I set it to replace the home feed with my subscriptions.
• Vimium. Provides keyboard shortcuts for navigation and control in the spirit of Vim. My settings are here.
• Wayback Machine. Reduce annoying 404 pages by automatically checking for an archived copy in the Wayback Machine.
