Logging in to multiple Facebook accounts
If you’re a Google Chrome user, you can use the script directly but if you are on some other browser, make sure it has the necessary add-ons before you proceed.
Once you have everything in place, install the “Facebook Switch Accounts” script in your browser and restart it.
If you log in to your Facebook account, you will see a new section at the top right panel named Switch Accounts. That’s the control panel that allows you to go from one account to the other.
Click on “Add Accounts” under the Switch Account menu and add all the accounts you work on simultaneously.
Now all you have to do in order to switch accounts is simply click the Switch account button and select the nickname of the account you want to switch to.
