If you have got a new PC/Laptop and you want to save your time, then its very important to import all your saved passwords from your old PC/Laptop because in this case you can directly login to any website whose password you previously saved.
Generally whenever you login to any website which needs authentication then most browsers ask you to either save the password or else never save the password, and in this post we are discussing about importing and exporting passwords in firefox browser.
These logins/passwords are generally stored in your browser files and you can anytime find them under Tools > Options > Security > Saved Passwords
You need to Export all your saved passwords along with the logins using a Firefox Plugin like Password Exporter
You need to install the Plugin, restart your browser and then go to Tools > Options to find out a new option which is ‘Import/Export Passwords’ where you need to click on Export Passwords option to get started.
Once you export it you will be given with a download file which you need to again import on your new PC/Laptop.
It will slowly start importing all your passwords along with a final report which can show you the result of your transfer process.
