User Reviews

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

Requires following advice from other commenters and applying some elbow grease to make this addon working, but after doing that, it works perfectly like how it is in Google Chrome. This should really be a core feature that should be included in Firefox.

Is Profile Switcher for Firefox Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Profile Switcher for Firefox requires a few sensitive permissions. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.
