New
• Classic image grid (Extras) — multi-image posts go back to a grid instead of X's side-scrolling carousel, so nothing is hidden off-screen.
• Extras is easier to find: a labelled row in the popup instead of a small sparkle icon, now grouped into Look and Timeline.
• X Dim Mode now runs on Firefox for Android as well as desktop.

Fixed
• Turning Dim off actually turns it off. The toggle used to leave the page dimmed until a reload, and the setting could switch itself back on.
• "Tweet, not Post" now also renames the big compose button in the sidebar — the most visible "Post" on the page, which it used to miss.
• The interface lays out right-to-left in Arabic.

Something broken? There's a "Report a problem" link in the popup.

Bug fixes

Bug fixes and improvements

New in Extras:
• Tweet, not Post — renames Post → Tweet and Repost → Retweet across the UI\
• Classic favicon — the blue bird returns to your tab, and it reads "Twitter" again
• Classic font — swaps X's Chirp back to the old Helvetica Neue look

Also new:
• Your theme and settings now sync across devices
• "Report a problem" link in the popup and Extras
• Join the newsletter right from the popup

Plus a more resilient theming engine and fixes for compose windows, Creator Studio, Premium cards, and the sidebar.

PWA title bar now matches your theme and reduced permissions.
