Hello.
Firefox Portable 115.17.0esr 64 bit, Windows 7 x64.
If you install the Firefox flag as a default browser...
Then, when opening the link, for example, from the postal program, the browser opens a new window, while it uses the default settings. I think he does not see his main profile.
Can I fix it?
Can you make so that a new tab opens, not a window?
Thanks.
