I've been using Librewolf on my Linux box for years, but my work PC had Firefox portable on it. I want to make the switch there, but FF isn't listed on the browsers to import from.

I could copy the profile folder, but I'm afraid of overwriting the sane LW defaults with less private FF settings.

How can I solve this? Is there a way to import stuff (plugins, history, etc) without overwriting privacy and security settings? Or perhaps a way to reset privacy and security settings without losing the rest of the preferences?

Edit: I also asked this on LW's official Matrix support channel, and it looks like my fears are mostly unfounded. Thanks to any1here who answered this, and is the Setting Maintainer for the project and overall chill chihuahua.

-- You would only be copying over user prefs, which are things you explicitly set in Firefox, not the Firefox default settings

-- When I create a profile, my user prefs are blank, the defaults are not copied over to the profile at creation? So the only thing that is written there are the prefs I change away from defaults?

-- Basically yes. There are a few things that get written by itself, but nothing important
