How do you propose getting rid of the PSL? I don't see alternatives to having an authoritative publicly available list, unless we change the current standards somehow?

the PSL is available at https://publicsuffix.org/list/public_suffix_list.dat - as noted elsewhere in this tread it is also used by other browsers. I guess the one built into Firefox is just downloaded from there and cached? If so why would you want that over the other?

I do not have a concrete proposal. If I did I'd probably be too busy arguing about it with other people in that space to comment here.

If your extension is 10kB of Javascript and you typically update it once or twice a year to tweak things, it's crazy that now the total extension size is over twenty times bigger and you need updates every month or so at least because otherwise things might not work for some users.

If your extension wraps, say, the New York transit map, or Wikipedia's list of English monarchs then fine, there's no reason Firefox would know those, you need to ship or fetch the data. But the PSL is necessarily built-in to Firefox, they do have the data, you just can't access their copy.

I was thinking about downloading the data at runtime, not baking it into the extension source. Obviously I don't know what your extension does and maybe there are reasons why this is not possible (e.g. maybe that's not doable because you need offline support).
