Regarding profiles creation, I suggest adding an option to password-protect each profile. This would be much better than (about: Profiles), which is also a password-free profile.
You can protect your entire computer User Account by using a password to logon to user account. Thunderbird runs in the User Account, so you would need to know the password to user account just to start Thunderbird in that account. this is already available.
However, if you allow people access to your computer AND allow them acess to your User Account, you can set up a 'Master Password' to operate on your Profile.
In that instance it will not stop people seeing emails but it will stop them from seeing any stored passwords. No master password - no access to stored passwords.
A 'Profile' can contain many mail accounts - do not confuse the difference between a mail account and a profile.
If people are sharing same computer and all have access to same user account, then different people should have their own profile to contain their own mail accounts. When you start up Thundrebird, the shortcut should be configured to open the 'Profile Manager' where the desired 'profile name' can be selected. If all users have own 'Profile', they can already set up the 'Master Password' to operate on their entire profile protecting the various stored passwords to their mail accounts.
Obviously the best approach is for each user on same computer to have their own User Account login with own password. Then no one sees each others emails as Profiles are stored specifically within a computer User Account.
You just have to click on “Cancel” to bypass the master password protection… not very secure. I would like this protection to prevent Firefox from being used with my profile. My computer is shared with other users, with whom company data is shared without any issue. I simply want to protect my personal browsing profile.
Profile anlegen für Familienmitglieder und diese dann auch mit Passwort schützen, so das sie nicht geöffnet werden können, das würd ich mir wüschen für sicherheit. Wenn meine Kinder am pc sind, haben sie ihr eigenes profil und dort sind auch sehr viele seiten gesperrt. leider haben sie auch die möglichkeit mein profil zu öffnen und dort ist natürlich alles freigeschaltet und sie können jede seite öffnen. darum würd ich mir wünschen, das man profile mit passwort schützen kann. mozilla ist das egal was wir nutzer wollen, die ziehen einfach ihr ding durch, was ich schade finde, sieht man auch am vpn. nicht mal ein paar vpn server sind gratis, soviel zum thema sicherheit. opera browser hat eingebauten vpn dort sind 5 server gratis, auch die profile kann man schützen mit passwort, da ist noch viel luft nach oben für mozilla. ich nutze mozilla, weil es einfach übersichtlier ist und mehr addon gibt.
Password for individual profiles to open.
Creating profiles for family members and then protecting them with a password so that they cannot be opened is what I would like for security. When my children are on the PC, they have their own profile and many pages are blocked there. Unfortunately you also have the option to open my profile and of course everything is unlocked there and you can open every page. That's why I would like to be able to protect profiles with a password. Mozilla doesn't care what we users want, they just do their thing, which I think is a shame, you can also see it on the VPN. Not even a few VPN servers are free, so much for security. opera browser has built-in VPN there are 5 servers for free, the profiles can also be protected with a password, there is still a lot of room for improvement for Mozilla. I use Mozilla because it is clearer and has more add-ons.
