I get backup from my filrefox such as :

cp -rv ~/.mozilla/firefox/* /mnt/my_external_hdd_mounted/myfirefox/

In new linux I did the following steps:

1. rm -rf .mozilla/firefox/* 2. cp -rv /mnt/my_external_hdd_mounted/myfirefox/* ~/.mozilla/firefox/ 3. chown mohsen.mohsen -R ~/.mozilla/firefox/

By the way, both of them are version 91.

But after run of firefox, I get the error of attached picture.

Ok, don't worry.

You have firefox-esr in new linux-box and your old firefox was firefox. You need to remove firefox-esr and install firefox. Then copy your backup.
