## Summary
Mozilla has released several Firefox improvements alongside an updated public development roadmap. Recent changes include a PDF viewer that launches up to 45% faster on desktop, optional bottom-positioned tab bars on Android, faster video seeking on desktop, persistent custom wallpaper collections on New Tab, and a Smart Window beta in the U.S. and Canada that can fill forms using information from open tabs and monitor pages for changes like price drops.

The updated roadmap outlines six features in active development: Mini Window for floating page fragments, text-to-speech reading on desktop and Android, offline article saving on Android, on-device speech recognition for desktop websites, per-site VPN rules, and a toolbar button for clearing browsing data in Classic Window. Mozilla notes these are being developed in the open with contributor involvement, with release timing to be announced as features mature.

## What changed in Firefox and what's coming next
- **PDF viewer performance:** The built-in PDF viewer now starts up to 45% faster on desktop, reducing latency when opening documents in-browser without external application dependencies.
- **Android UI customization:** Users can now relocate the tab bar to the bottom of the screen via Settings > Customize, addressing ergonomic preferences on mobile devices.
- **On-device speech recognition (roadmap):** Firefox will download a local speech recognition model to enable voice input and captions on desktop without server-side audio transmission, with offline transcription capability after initial model download.
- **Per-site VPN rules (roadmap):** Building on the free built-in VPN already available on desktop and Android, users will be able to configure site-specific VPN behavior rather than applying a global toggle.

## Why it matters
The on-device speech recognition and per-site VPN controls represent a privacy-oriented alternative to cloud-dependent browser features, potentially establishing patterns other open-source browsers could adopt. For Linux users and system administrators managing Firefox deployments, the roadmap's emphasis on offline functionality and local processing aligns with growing requirements for air-gapped or privacy-sensitive environments, while the public roadmap process itself offers unusual visibility into a major browser's prioritization compared to closed competitors.
