## Description

**Profile Switcher for Firefox** is a powerful extension designed to streamline your browsing experience. It allows you to create, edit, delete, and set your default Firefox profiles effortlessly.

## Review summary

Most reviews say the extension can be very useful and works well once the external helper and a manual config.json are set up. However, many users report a fragile installation process, unresponsive profile switching, and compatibility problems with certain Firefox builds or packagings. Additional concerns include extra privileges requested by the helper, incomplete uninstalls, and apparent lack of active maintenance.

### Pros

- Works reliably after performing the documented workaround/connector setup
- Convenient way to switch profiles (easier than using about:profiles) — many users call it very useful or professional
- Has working integrations on some platforms (Arch Linux/AUR, macOS) when configured properly

### Cons

- Requires an external helper/connector and manual config (e.g. creating config.json with browser\_binary)
- Initial setup is fragile — many users report it doesn’t work immediately or buttons are unresponsive
- Compatibility problems with some Firefox builds/packaging (Flatpak, Dev, forks, Zen browser)
- Helper may request extra privileges and there are concerns about security/privilege requests and incomplete uninstalls
- Perceived lack of maintenance (last update long ago) and intermittent developer support
