I would like to manage Firefox extensions in the same way as configuration option programs.chromium.extensions for chromium. Is there anything like that?
I would be very interested in this for the firefox module in Home Manager. I’ve briefly looked at this at some point but haven’t really found any great solution. From what I can tell it is sometimes possible to put the XPI file somewhere and Firefox will pick it up on the next restart but I would really like some nice and simple explanation.
