I use profiles on desktop, but also use multiple browsers, and multiple versions of browsers, especially on mobile, for different purposes: - Firefox Focus as default browser when clicking links from native apps to always open it with an empty cookie jar - Brave Android as default manual browser, and for watching videos (audio only) with screen turned off - the only browser to support it, behind a pref - Opera Android when I need to zoom & have text to reflow (it's the only browser which supports this, behind a pref) - Separate browser only for social media, to not mix history with default browser. I used to use Firefox profiles long time ago on desktop, but as it required command line flag, and was not first-class UI supported, I started instead using Firefox Stable / Dev / Nightly.
