Every feature, explained
Two extensions. Every feature explained. Zero telemetry.
SuperchargePerformance
Speed up Chrome. Free RAM. Block ads and trackers.
Tab Suspender — Free Chrome Extension
Unloads inactive tabs using Chrome's native API to free memory. Pinned tabs, audio tabs, and whitelisted sites are always protected.
Ad Blocker — Block Ads and Trackers in Chrome
Blocks ads, trackers, analytics, and malware/phishing at three coverage levels. All rules ship with the extension — no external list fetching, ever.
Script Blocker — Block Third-Party Scripts
Blocks third-party scripts loaded from external domains — social widgets, analytics, and trackers — while leaving login and payment flows untouched at PRO level.
Font Optimizer — Use System Fonts for Speed
Blocks web font downloads and substitutes system fonts, reducing page weight and improving load speed. Three levels let you choose how aggressively fonts are replaced.
Lazy Loading — Prioritize Visible Content
Defers loading of below-the-fold images, iframes, and off-screen resources so the content you can see loads first. Three levels of coverage available.
Link Preloading — Instant Page Navigation
Starts loading likely next pages in the background before you click, so navigation feels instant. Two levels: same-site only or all domains, both free.
Stop Autoplay — Block Video Autoplay
Stops videos from autoplaying across the web. Choose between blocking everything or allowing major video platforms and conferencing tools while stopping the rest.
Safe Mode — Auto-Recover Broken Pages
Detects when a page has been broken by SuperchargePerformance's features and automatically disables them on that page. A safety net for aggressive settings.
Site Whitelist — Per-Feature Domain Exemptions
Exempt any domain from specific SuperchargePerformance features. Block ads on everything except your banking site. Keep Spotify active while still blocking its ads.
SuperchargeNavigation
Vertical tabs. Persistent workspaces. Tab search.
Vertical Tabs for Chrome — Side Panel Tab Manager
A persistent vertical tab list in Chrome's native side panel. See all open tabs, groups, and pinned tabs at a glance — drag to reorder, multi-select for bulk actions.
Browser Workspaces — Save and Switch Tab Sessions
Save any set of tabs as a named workspace and switch back in one click. Tab groups, pinned tabs, mute states, and group colors are all preserved. No cloud account required.
Session Time Travel — Auto Tab Snapshots
Auto-snapshots your tabs every 5 minutes. Rewind to any point and restore as a new workspace — a safety net no other extension offers.
Tab Search — Command Palette for Chrome
Alt+K opens a full-page Spotlight-style search across open tabs, bookmarks, and browsing history. No match? It falls through to a web search automatically. Your Arc command palette, in Chrome.
Smart Tab Grouping — Auto-Group by Domain
Alt+G groups all open tabs by domain in one keystroke. Inactive groups auto-collapse to reduce clutter. Alt+Shift+G undoes all grouping instantly.
Glance Peek — Preview Links Without a Tab
Shift+Click any link to preview its content in a full-screen overlay without opening a new tab. Read what you need, then dismiss or promote it to a real tab. Arc's Peek, for Chrome.
Super Drag — Open Links by Drag Direction
Drag any link up to open it in a background tab, or drag it down to open it in the foreground. Drag selected text to launch a search. Automatically disabled on web apps like Google Docs and ChatGPT.
Tab Deduplication — No More Duplicate Tabs
SuperchargeNavigation detects when you open a page that's already in your browser and prompts you to switch to the existing tab rather than creating a duplicate. Enabled by default.
