Do Chrome extensions slow down browsing?▾
Yes, some do — particularly extensions that run on every page load or inject JavaScript. Extensions like ad blockers (uBlock Origin) actually speed up browsing by blocking resource-heavy ads and trackers. To identify slow extensions, use Chrome's Task Manager (Shift+Esc) to see memory and CPU usage per extension.
Are Chrome extensions safe to install?▾
Extensions from the Chrome Web Store go through automated security scans, but malicious extensions do occasionally pass review. Best practices: only install extensions with many reviews and a reputable developer, check requested permissions before installing, and regularly audit your installed extensions removing ones you no longer use.
What are the most useful productivity Chrome extensions?▾
uBlock Origin (ad blocking), Bitwarden (password manager), Grammarly (writing), Notion Web Clipper (saving content), Dark Reader (dark mode), and a tab manager like OneTab are consistently rated among the most useful productivity extensions. AI-powered extensions like Sider and Merlin bring ChatGPT-style AI to any webpage.
Will Chrome extensions work in other Chromium browsers?▾
Most Chrome extensions work in any Chromium-based browser — Edge, Brave, Arc, Opera, and Vivaldi all support Chrome extensions directly through their own extension stores or by enabling developer mode. Firefox has its own extension ecosystem (some overlapping extensions, many the same ones with a Firefox version available).
