Mozilla rolled out Firefox 150 on April 20, 2026, with binaries hitting its FTP servers ahead of the official site launch the next day. Users on Windows and macOS saw in-app updates soon after. Linux fans grabbed it via Snap on Ubuntu or Flatpak from Flathub. This monthly drop packs practical tweaks that power users will notice right away.
Split View steps up big time. Right-click any link now to open it alongside your current tab. Want to flip them? Context menu handles that. Search your open tabs when starting a new split, too—pick exactly what pairs best. It’s these details that make multitasking smoother without extra extensions.
Tab handling gets smarter. Shift-click multiple tabs, right-click the bunch, and share all their URLs at once. Copy {$num} links, as Firefox labels it, ready for pasting into notes or chats. A new setting under Tabs lets you turn off accidental drag-and-drop grouping. No more surprise clusters.
PDF editing expands. Reorder pages. Copy and paste them between documents. Delete what you don’t need. Export just the ones you want. Drag a local PDF into the browser to start—simple as that. OMG! Ubuntu flagged this as a standout for quick document fixes.
Translations go private. Type ‘tra’ in the URL bar, hit the translate chip, and land on about:translations. Paste text, pick languages, watch real-time results—no cloud involved. On-device processing keeps your words off servers.
URL bar does math now. Punch in ‘1000 mph to km/h’ for instant conversion. Click to copy. Small? Sure. But try it during a meeting. Saves seconds that add up.
Security tightens across the board. Local network access demands permission from every site, not just Strict mode users. Websites can’t poke your printer or smart fridge without asking. This rolls out gradually to all. Firefox Beta notes previewed the shift back in March.
Linux users: Ctrl + . triggers the native GTK emoji picker in text fields. No more clunky workarounds. RPM packages join the download page for Fedora, openSUSE, Red Hat crowds—standalone, no distro repos needed. 9to5Linux called out the emoji win first thing.
Windows tweaks include profile manager and backups for versions 10 and 11. Microsoft Store installs gain web apps. Practical for IT admins juggling setups.
Developers feast here. New AriaNotify API pushes accessibility alerts. Pseudo-classes :playing and :paused style media elements by state—muted, stalled, you name it. highlightsFromPoint() grabs focused items. light-dark() mixes image colors for themes. Lazy-loading images auto-size via srcset. DevTools adds a pseudo-class toggle panel. MDN’s Firefox 150 developer notes lists them in beta detail; they stuck for stable.
Phoronix zeroed in on Linux emoji and media pseudo-classes, tying them to Mozilla’s open-source push amid AI browser hype. No flashy experiments this round. Just steady gains.
And the rollout? Smooth. FTP drops Monday, full site Tuesday. Beta hit March 25, per Firefox train schedules. ESR buddies 140.10 and 115.35.0 tag along. Security patches fill the notes, live post-release.
Neowin captured the buzz: improved Split View, beefier PDF tools, tab sharing. Their roundup matches on-the-ground tests. X chatter echoed it fast—posts from @9to5linux and @NeowinFeed lit up feeds April 20.
Firefox keeps its cadence: features monthly, stability first. Power users get tools that stick. Casual ones? Faster PDFs, quicker splits, safer nets. No bloat. Mozilla bets on that formula as Chromium forks chase flashier paths.
Grab it from Mozilla FTP. Updates push soon. Full notes pending at release page.
