Best Firefox Extensions for Twitter (X) in 2026
Looking for Firefox extensions for Twitter, now X? In 2009 a guest writer here listed ten favourites: TwitterFox for notifications, TwitBin and TwitKit sidebars, TwitterBar for posting from the address bar, Power Twitter, Twitzer for long tweets and more. Every one of them has stopped working, killed by Firefox’s 2017 add-on overhaul and by X’s paid API. A few new extensions have taken their place. Here’s what works for X in Firefox in 2026.
Quick answer: The most useful Firefox extension for X in 2026 is Control Panel for Twitter, which keeps you on the chronological Following feed and hides clutter and algorithmic content. For everything else, use Firefox itself: pin x.com as a tab, share pages with a one-click bookmarklet, and use Firefox’s own notifications and container tabs to manage multiple accounts.

Firefox extensions for X that work in 2026
- Control Panel for Twitter: actively maintained; defaults your Home to the Following feed, hides For you, lets you hide or move reposts and quote posts, removes engagement counts and tidies up promoted and distracting elements.
- Firefox Multi-Account Containers: Mozilla’s own extension for staying signed in to several X accounts at once, each in its own colour-coded tab.
- uBlock Origin: blocks ads and lets you hide any element on x.com with its element picker.
Before installing any X extension, check that it was updated recently and read its permissions; extensions that access every site can see everything you do. Here’s how to manage Firefox extensions.
Do it without an extension
Post any page to X
TwitterBar once let you post from the address bar. Today a bookmarklet does the same in one click: see how to share any page on X.
Keep X open in a pinned tab
Right-click the x.com tab and choose Pin Tab. It stays small, loads at startup and shows a dot when there’s new activity, like the old notifier extensions.
Get notifications
Allow notifications for x.com when X asks, or in Firefox Settings > Privacy & Security > Permissions > Notifications. You’ll get alerts even when the tab is in the background.
Long posts and link previews
Twitzer let you post past 140 characters. Free X accounts now get 280 characters, and Premium subscribers can write much longer posts. Shortened links are expanded by X itself.
What happened to the 2009 extensions?
TwitterFox, TwitBin, TwitKit, TwitterBar, Power Twitter, Twitzer, StockTwits, Song.ly and TwittyTunes were built for Firefox’s old XUL add-on system and Twitter’s free API. Firefox 57 (2017) dropped legacy add-ons, and Twitter shut its old API versions, so none of them can be installed or work today.

FAQ
Is there an official X extension for Firefox?
No. X doesn’t publish an official browser extension; use x.com directly.
Can I use X’s old layout in Firefox?
Not fully. Extensions like Control Panel for Twitter can restore a simpler, chronological feed and hide many newer elements.
Are X extensions safe?
Stick to well-reviewed extensions on addons.mozilla.org that are updated regularly, and avoid any that ask for your X password.

is my favorite Firefox twitter addon by far. It doesn’t stall like the others and has a really cool retweet and mutual friends function… AND it has added functionality that will let you post to facebook and foursquare as well!
Please use #hashtags for easy theme monitoring by twitter search.
Hello,

Would prefer something that allows me to click a button for a retweet….
