Dec 2025: Retiring the Fallen London extension whitelist
In the early days of Fallen London we maintained a whitelist of browser extensions which people found useful and which tweaked the game in ways we weren’t planning on including in the game proper.
Over the years, many of the functions they performed were superseded by game updates or otherwise rendered unnecessary or unusable. Most of the extensions on the whitelist are no longer maintained, and the most popular extensions in current use have never been whitelisted.
As of today, the whitelist no longer stands: we will no longer be adding anything to it, and the designation of ‘whitelisted’ no longer exists. You can keep using existing extensions if you want, providing they don’t break the terms of service; we will still come down on the use or development of any extensions which make API calls or otherwise break the terms of service.
The above supersedes any information about whitelisted extensions you may have seen elsewhere.
Our position on extensions
There are fan-made extensions for Fallen London which are designed to tweak the game in ways we don’t plan to ourselves. Our current position on extensions:
Extensions are third party. There is no official support for them, your mileage may vary and you use them at your own risk.
If you encounter problems with them (or any aspect of the game while you have them enabled) please remove the extension(s) and try again before contacting support.
Updates to the game may break extensions, and the responsibility for updating the extensions falls to the individual who created them.
*We will not add these functions to the game. They are optional extras, so don’t ask. :)
We reserve the right to remove this post or change our position on this at any time.

Public service post: if you have any of these (or other) FL extensions installed, your first move should probably be to disable them as soon as strange things start happening while using the new site.
I suspect none of the extensions will even try to run on the new site. As I understand it, extensions activate based on domain name, so the change from storynexus.com to fallenlondon.com should mean they don’t recognize the new site at all.
[quote=Zarremgregarrok]A big warning to anyone using Stylish as a method of delivery of their Fallen London extension.
The extension is no longer considered safe. (Sends all your browsing data to extension owner’s server) Use extension Stylus instead. https://arstechnica.com/information-technology/2018/07/stylish-extension-with-2m-downloads-banished-for-tracking-every-site-visit/ edited by Zarremgregarrok on 7/28/2018[/quote]
Aided by an anonymous benefactor (OK, it was Tuxi) who redid all the item IDs for me, the overhauled Winking Isle Indicator 2018 is now up on Stylish, and as far as I can tell, it works (note that I have not got a full inventory of the most esoteric items in the game to check).
The Winking Isle Indicator thread does encourage the use of it with Stylus, not Stylish, but perhaps I should hint more strongly that there is no downside to Stylus AFAIK, whereas there is plenty to Stylish.

I would not worry too much. Stylish was removed from Google Play Store, so it is impossible to download it.
I’ve written a option/opportunity protector style for the FL redesign. It basically combines Gazzien’s and fallingkitten’s old styles + a few more options (e.g. accidentally ditching acquaintances or overcapping as a PP). The style has been officially whitelisted by Failbetter.
I know that a number of other players have also written similar styles, but none are listed here. So I thought I’d post a link.
(I’m recommending using Stylus over Stylish because of the tracking issues with the later.)
I’ve updated the style a couple of times over the past weeks due to changes to the FL code. Let me know if anything isn’t working correctly and I’ll take a look.
