JoshStrobl Hmm looks like what I was trying to convey was missed: I used to do what you say but I stopped. The distinct browser helps remind me that "I'm being watched". When I see a Firefox window "I feel safe" whereas when I see a Chrome-looking window "I feel like I'm being spied on".
Perhaps it's just me but oftentimes I'd forget and log into gmail in FF and stay logged in without realizing. Once I switched to the "completely segregated browser" approach I stopped making that mistake. In fact, I don't even care if it's Chrome or Chromium or even Vivaldi, as long as it's "something that's not Firefox".
P.S. One other less important thing: Citrix Workspace App only works with Chromium-based browsers; the FF plugin does not work as they have not updated it. So I use Chromium/Vivaldi to log into work as well and run the native ICA client.
