I can't define default options for the extension. The only apparent way to be able to copy configurations over to other machines is to download the backup JSON file from the extension's configuration page and then manually restore using that file.

uBlock supports configuration through policies, and I was wondering if I'm doing something wrong or if this isn't currently possible with Vimium. There's even a GitHub page by Mozilla using uBlock as an example.

I should note that I am using Home Manager, though it works just fine for uBlock and other policy configurations.

To Reproduce

1. Try to define policy with contents of backed up vimium-options.json file, or even just a single option like scrollStepSize (either through Nix or normally).
2. Vimium does not load the configuration.

See "3rdparty".Extensions; the other options are unimportant:
