You first went to the browser and created a profile. Let’s call it profile 0.
You decided to pin it to the Windows taskbar. Everything is great
You have decided to create another profile. Let’s call it profile 1. You decided to pin it to the Windows taskbar. Everything is fine.
And you decide to click on your profile 0 in the taskbar. And this is where the problems begin. Now it will prompt you to choose which profile to open, and if you disable this feature, it will open the LAST used profile.
And if you want to pin 2 different ones to the Windows taskbar, then you will have to create another profile (2) and transfer all your data there.
Tested on Windows 7 & 10.
