Yes, I'd like to use the same account on both of my profiles. I understand that for some users, this may be confusing. In my case, the only reason for different profiles is that I need to use a Proxy Server for some websites, and no proxy for other websites. Manually switching proxy settings is painful, and doing so causes traffic for my other tabs/windows to go to the proxy, which I do not want. I have a main (set of) windows (and its tabs) going straight to the internet, then I have a separate window (and its tabs) configured to go through a proxy (SOCKS5 in this case). I want all other settings, bookmarks, passwords, etc. to be identical to both. I end up having to logout of my main profile, log into the other profile to sync settings, log out of there, and log back into my main profile. Is there a valid technical reason why an account on the same FireFox installation cannot be shared between two profiles? I can do this on multiple computers (same account, different computers/profile), seems odd it is restricted to not allow on the same computer. I have an alternative solution: Install FireFox natively, then install FireFox as AUR or FlatPak, but not sure this will collide as this both uses the same profile directory. Hum... Wayne
