Mozilla Firefox will be enabling a profile management feature from 14 October 2025. The new profile manager lets users separate browsing activities easily.
The last time I tried it, it was a whole different manager that kept its own database of profiles, and didn’t work with parameters. So if you had a dock shortcut with a menu to open different profiles (as in GNOME), or used a custom system-wide keyboard shortcut or mouse gesture to open different profiles, this didn’t work because it needed to run firefox -P "profile" and it opened a whole different profile.
The article here doesn’t specify if this is still a problem, and instead talks as if Firefox never had a profile manager. 🤷🏻♂️
I’m on beta 145 with the new PM disabled, so hopefully we’ll still get the option to use the old school PM.
As far as I know you’ll still be able to use the old one. Presumably it won’t see much love, but I don’t think it hasn’t seen much love for years anyway.
That said, you probably won’t see those old profiles in the new profile manager, but if you’re happy with your current setup that doesn’t sound like much of a problem.
