## Description

Auto Fullscreen is a simple Firefox extension designed to automatically open all browser windows in fullscreen mode, including those opened after the initial launch. Unlike the original Auto Fullscreen add-on which only makes the initial window fullscreen, this fork ensures every window, even those created when opening tabs in separate windows, adopts fullscreen. This is perfect for users who prefer an immersive browsing experience across multiple windows. Additionally, users seeking to view bookmarks in fullscreen mode can follow provided guidelines (handling at your own risk). For bug reports or feature requests, contributions can be made via its GitHub issues page.

## Review summary

Users praise the add-on for reliably enabling automatic fullscreen across platforms (Linux and Windows) and for working especially well when combined with full-screen-api.ignore-widgets. Multiple reviewers requested additional features or fixes: bookmarks toolbar compatibility, per-site control, and a taskbar auto-show behavior in fullscreen.

### Pros

- Reliable and does what it promises—multiple users report it solved their fullscreen issues
- Cross-platform: users report it works on Linux and Windows
- Works especially well when used with the full-screen-api.ignore-widgets setting for a borderless/PWA experience

### Cons

- Missing some UI/feature integrations reported by several users (requests include making the Windows taskbar appear on hover in fullscreen)
- Bookmarks toolbar incompatibility reported by users
- No per-site control option (users requested the ability to limit fullscreen to specific sites)
