Install Thunderbird from a package manager. On Fedora I suppose that's DNF or RPM now, but it used to be yum or RPM. Some analogous folders between Windows and Linux (the File Hierarchy Standard): System-wide binaries (.exe) for userland software on Windows: C:\Program Files (x86)\ C:\Program Files\ System-wide binaries for userland software on Linux: /usr/bin/ /usr/local/bin/ System-wide configuration files on Windows: C:\Program Data\ System-wide configuration files on Linux: /etc/ Per-user binaries (.exe) on Windows: C:\Users\JillS\AppData\Local\ C:\Users\JillS\AppData\Local\Programs\ Per-user binaries on Linux: /home/jills/.local/bin/ (also various user-specified locations under /home/jills/) Per-user configuration files on Windows: C:\Users\JillS\ C:\Users\JillS\AppData\Roaming\ Per-user configuration files on Linux: /home/jills/.config/ (A different location can be specified on most Linux desktop setups (i.e., those that use the X Window System) by changing environment variable $XDG_CONFIG_HOME to equal the desired location) Admin (root) binaries on Windows: C:\Windows\ Root (admin) binaries on Linux: /bin/ /sbin/ The environment variable PATH works the same in principle on both Windows and Linux. On Windows you change PATH in the GUI "Edit environment variables for your account". On Linux you typically use a text editor to open one of the standard "dot" files in /home/jills/, such as .profile or .bashrc, and specify PATH in there. EDIT: It would help if you knew where Fedora's Thunderbird packagers put your Thunderbird email files. I think it's typically /home/multicomp/.thunderbird/ If that's true in your case, then just find your `x1y2z3.default` folders on Windows and copy them to that Linux directory. Not sure if the `.ini` files matter, but copying those shouldn't hurt.
