Firefox not importing bookmarks after 26.05 update

Help
1

I use Home Manager to configure Firefox, including importing bookmarks from a separate bookmarks.nix file. This setup worked on 25.11.
After updating from 25.11 to 26.05, Firefox suddenly stopped importing any of my bookmarks and it acted as fresh install. The fresh install isn’t a problem(it is Nix), but i seek help with the bookmarks

programs.firefox = {
  enable = true;

  profiles.default = {
    isDefault = true;
    settings = { };
    bookmarks = {
      force = true;
      settings = [
        {
          name = "Bookmarks Toolbar";
          toolbar = true;
          bookmarks = import ./bookmarks.nix;
        }
        {
          name = "NixOS Search";
          url = "https://search.nixos.org/";
        }
      ];
    };
  };
};

bookmarks.nix
[
{ name = "YouTube"; url = "https://www.youtube.com"; }
]

Whoops, just dont change the versions in home.nix and configuration.nix :hugs: and it will work.

I am having the same issue. In addition, extensions also have their configurations cleared, and the multi-account container plugin I use has lost all the containers I defined as well.

In ~/.mozilla/firefox/ you should find profiles.ini. This file points to your default profile, with a path, relative to the previous directory.

Not sure why, but the profiles.inipath now points to a new profile directory which is indeed a “fresh install” profile without all bookmarks and extension settings.

If you force copy the contents from the correct profile over to the new profile, you get the settings as intended.

This isn’t a fix of course, as it still doesn’t deploy the home-manager config to this profile. Just shows that for whatever reason a new profile is being created and set in the profiles.ini under the path property.
