Best Firefox Extensions for Social Media in 2026

In 2009, the way to turn Firefox into a social networking powerhouse was a sidebar extension that pulled Facebook, Twitter, MySpace and FriendFeed into one place. Those all-in-one add-ons are long gone, but the right Firefox extensions for social media can still make posting, sharing and staying private much easier in 2026. Here are the ones worth installing, and what happened to the originals.

Quick answer: The most useful Firefox extensions for social media in 2026 are Facebook Container (keeps Meta from tracking you across the web), Firefox Multi-Account Containers (log in to several social accounts at once), Buffer (schedule posts to many networks), Pinterest Save Button and Grammarly (check posts before you publish). Yoono, Glue and Firestatus from the original 2009 list no longer exist.

Best Firefox extensions for social media in 2026

• Facebook Container: made by Mozilla. It opens Facebook, Instagram and Messenger in a separate container so Meta can’t follow you on other sites through like buttons and trackers.
• Firefox Multi-Account Containers: also from Mozilla. Give each social account its own coloured tab container, so you can be logged in to a personal and a brand account on X, LinkedIn or Instagram at the same time.
• Buffer: share the page you are reading to X, Facebook, LinkedIn, Instagram, Threads, Bluesky and Mastodon, or add it to your posting schedule. The modern take on the old Firestatus one-click update button.
• Pinterest Save Button: save images from any web page to your Pinterest boards with one click.
• Grammarly: checks spelling, grammar and tone as you type posts, comments and messages on any social site.

What happened to the 2009 extensions

• Yoono put Facebook, MySpace, Twitter, Flickr and several instant messengers in one Firefox sidebar, with a “discovery” widget for related links. It was discontinued years ago, and most of the services it supported have closed or locked down their APIs.
• Glue showed what your friends thought of the movie, book or product on the page you were viewing. It became GetGlue, then tvtag, and shut down at the start of 2015.
• Firestatus updated your Facebook, Twitter, FriendFeed, Delicious and Identi.ca status from the Firefox status bar. FriendFeed and Identi.ca are gone, and Firefox dropped the status bar and that type of extension.

Today, each network is best used in its own tab or app, and extensions focus on privacy, scheduling and saving rather than one giant social sidebar.

Tips for using social media in Firefox

• Pin your most-used social sites as pinned tabs so they stay open and take little space.
• Use Firefox’s built-in Enhanced Tracking Protection on Strict if you want to block more social trackers.
• If social sites eat your time, set limits with the tips in our guide to block Facebook, Twitter and email for a few hours a day.
• Bloggers can find more sharing and scheduling tools in our list of Twitter tools for bloggers, and keep their browser safe with these Firefox security add-ons.

FAQ

Is there a Firefox extension that shows all my social feeds in one place?

Not a good one any more. Networks restrict their APIs, so all-in-one feed readers like Yoono stopped working. Use a social media manager such as Buffer for posting, and each site’s own tab for reading.

Does Facebook Container block Facebook?

No. Facebook works normally inside the container. The extension only stops Facebook from seeing what you do on other sites.

Can I log in to two Instagram or X accounts in Firefox at once?

Yes. Install Multi-Account Containers and open each account in a different container tab.
