r/facebook on Reddit: mbasic is going away on 28 October 2024 - what's the alternative?
October 17, 2024 -

Apparently mbasic.facebook.com is going away on 28 October 2024.

Facebook are just saying it's to "enhance security and optimize the user experience", both of which are lies (unless they mean optimize from their point of view, not ours).

They say "on older versions of mobile browsers" and recommend using the latest Chrome or Firefox. Which is also a lie because the latest version of Firefox shows exactly the same warning.

So what's the alternative now?

Things I really like about mbasic - you can right click (or long press) on text and copy/paste it elsewhere, and you can open something in a new tab.
