Bookmarks and history never mix
Chrome's profile feature lets you fully separate your work and personal browsing environments, so bookmarks and saved logins from one never bleed into the other. Each profile behaves like an entirely independent browser.
Juggling multiple accounts elsewhere too?
If you also manage several email accounts and want to switch between them quickly, it's worth checking whether your email provider offers a similar quick-switch feature between accounts within a single window, separate from Chrome's own profile system.
Frequently Asked Questions
Can each profile have different extensions?
Yes. Each profile is a fully independent environment, so extensions, themes, and settings can all be configured differently per profile.
If I delete a profile, is its data gone too?
Deleting a profile also deletes the bookmarks, history, and other data stored in it, so back up anything you need beforehand.
