## Description

Progressive Web Apps for Firefox lets you install websites as standalone, app-like experiences by creating a custom Firefox runtime. The project provides a browser extension and a console tool to install, manage, and launch PWAs (site-specific browsers), enabling native-like behavior for cross-platform web apps using existing web APIs and progressive enhancement.

The extension is open-source and privacy-aware: communication with the native messaging host is limited to local install actions (manifest and site URLs) and stored locally. See the documentation and GitHub repository for installation instructions, source code, and active discussions to suggest improvements or request features.

## Review summary

Overall, users praise the extension as reliable and well-executed when it works, with strong Linux support and useful cross-profile syncing (e.g., Bitwarden, uBlock). It’s seen as a valuable bridge until Firefox gets native PWA support. Recurrent drawbacks center on cross-platform installation/setup issues and login persistence with separate profiles, plus occasional UI quirks and minor post-update regressions. Despite hiccups, many feel it significantly improves PWA workflow.

### Pros

- Reliable and well-executed when it works.
- Supports multiple profiles and cross-app syncing (e.g., uBlock, Bitwarden) across Firefox apps.
- Good Linux compatibility across distros (Debian, Fedora, Gentoo).
- Reimplements missing PWA functionality, bridging the gap until native Firefox support.

### Cons

- Installation and setup issues across platforms, including Windows Connector Installation problems and Ubuntu Snap packaging.
- Login persistence and forced separate profiles cause repeated logins and setup friction.
