What is the Difference Between m.Facebook and l.Facebook?

When accessing Facebook on a mobile browser, you may notice two similar looking URLs – m.facebook.com and l.facebook.com. What exactly is the difference between the m and l versions of Facebook’s mobile site?

In this guide, we’ll compare the m.facebook and l.facebook mobile interfaces and capabilities to understand the distinction between these two Facebook mobile offerings.

Facebook’s Mobile-Optimized Websites

To optimize the Facebook experience on mobile devices, Facebook offers:

  • m.facebook.com – Designed for older phones and basic mobile browsers
  • l.facebook.com – Made for modern smartphones with full features

The “m” and “l” denote mobile and lightweight versions of Facebook’s website specifically formatted for mobile screens.

M.facebook.com is Facebook’s original basic mobile site:

  • Launched in 2006 for early mobile phones
  • Stripped down version of desktop site
  • Focused on key features like News Feed

  • Enter Facebook email or username
  • Input password
  • Submit login credentials
  • Authentication works interchangeably

You remain logged into your one Facebook account regardless of visiting m vs l.

Posting is also nearly identical between the two:

  • Add stickers, apply filters, tag friends
  • Post visibility settings are the same

Any differences in posting are due to media limits for m.facebook.

Like the desktop site, privacy settings control who can see your posts:

  • Adjustable to Friends, Public, or a Custom list
  • Your posts don’t automatically become more public based on using m.facebook or l.facebook
  • Privacy settings carry between all interfaces

The version of mobile site does not change post visibility and privacy.

Accessing Messages and Notifications

Messages and notifications function similarly across both:

  • Notifications for reactions, comments, shares on your posts
  • Ability to read and respond to private messages
  • Notifications surfaced on both sites
  • No significant difference in messaging capability

You don’t miss notifications by using one versus the other.

Availability of Ads and Marketplace

Ads and Marketplace access varies slightly between the sites:

  • Both m.facebook and l.facebook display ads
  • Marketplace is available on l.facebook but absent from m.facebook
  • l.facebook may see more interactive ad formats
  • Ad performance metrics differ for the two sites

  • l.facebook supports facial recognition login
  • Both request notifications permissions
