One site, several accounts, at the same time.

Every tab runs in its own separate profile — for example, open two different Instagram accounts side by side. A tab closes only with ✕, and its sign-ins are erased when it closes; tabs are restored when you reopen the app. Incognito, a true desktop mode, a downloads manager (PDFs open straight in Office), save page as PDF, print, translate, find in page, night mode and text size.
