Issue description

Okay, so, I'm trying to import a lot of bookmarks into Firefox. Works fine with something like this:

    programs.firefox = {
      enable = true;

      profiles.username = {
        settings = {
          "browser.bookmarks.file" = "${config.home.homeDirectory}/.dotfiles/nixos/modules/home-manager/firefox/bookmarks.html";
          "browser.places.importBookmarksHTML" = true;
        };
      };
    };

But, if I change the path to a, well path, instead of a string, no matter if relative or full, the resulting user.js contains the following:

user_pref("browser.bookmarks.file", "\"/nix/store/3rbwiydh7hwykzwiyq3wsf34n4zhyvni-bookmarks.html\"");

Notice the escaped quotation marks inside the quotation marks, Firefox will fail to import that file. Works fine if it's a string though, but it has the full path to my dotfiles-folder, not the Nix store, which feels very.. un-Nixy.

Not sure if this is maybe a Nix-issue, path to string conversion or something? I've tried looking in home-manager/modules/programs/firefox.nix but I'm so new to this whole ecosystem/language I couldn't quite figure out where the error was.

Late to this, but just ran across some issues here myself. If you use string interpolation with a relative path, it should work. consider this:

    programs.firefox = {
      enable = true;

      profiles.username = {
        settings = {
          "browser.bookmarks.file" = "${./bookmarks.html}";
          "browser.places.importBookmarksHTML" = true;
        };
      };
    };

This assumes your .nix file and your bookmarks.html are in the same directory, of course. Adjust as necessary.

Here's my implementation: https://github.com/alyraffauf/nixcfg/blob/e829a2d4f85651d9fcf6fc9c884caf5c3a4523d1/homes/aly/firefox/default.nix#L22
