How to access few Facebook accounts on the same PC or device

Did you ever have trouble to access more Facebook accounts at the same time? Yes I did, when I tried to access another account then the previous account will be logged out automatically. 

Since last year I found the way to access many Facebook account on the same device (PC, tablet or Smart phone), first you have to download and set up internet browsers more than one on your PC or Smart phone, one browser for one account. For example: you access one account with Internet Explorer (IE), access the second one with Firefox browser, access the third one with Google Crome. 

If you use smart phone, you can access one account with Facebook app and more other accounts with default browser or download more browser such as Operamini.
