Are you an admin of any Facebook Page or Group? Then, still, you can officially switch back to the basic version of Facebook. And even, if you’re not an admin of any Facebook page or group. Then, you can create a new Facebook Page and get the option. Or, you can check out the rest solutions.
Open Facebook Page or Group of which you’re Admin.
On the right side of the Manage Page section, under your page name, you will see a “Switch now” option. Click on it.


Or, you can just click on Skip. And, classic Facebook will get open instantly.

Well, as per written by Facebook, this option can give you old Facebook Access for only 48 hours. So, If this “Switch Now” option gets vanished after 48 hours, then you can try the next method.
A Facebook user “Tarun Alex” posted a JavaScript in “Coders of XDA OFF-TOPIC GROUP!” to switch back to the Classic version of Facebook. And, I have tested it, and it works like charm. To use this JavaScript, we’re going to create a bookmarklet in Chrome. If you’re not aware, a bookmarklet is a bookmark stored in a browser that contains JavaScript commands. Usually, Bookmarklets are used to add new features to the browser. Or, we can simply call Bookmarklets a JavaScript program. So, here’s how, you can create a classic Facebook Bookmarklets, and use it.
First, do press Ctrl + Shift + B Keyboard Shortcut to show Bookmark Bar in Chrome. (If that’s already visible, then no need to press this shortcut.)
Right-Click on Bookmark Bar and then click on “Add Page…”.

And, in the URL section, copy and paste the following script and click on Save.
