Consider making Add-on settings container-specific
From https://discourse.mozilla-community.org/t/add-on-settings/14084
Example of addon that should be aware of containers: Self-Destructing Cookies This addon must have container settings separation - it is removing cookies after close tab. Unfortunately version 0.4.11 is not "container aware" - settings are shared on all containers (so it will remove cookies in "private" and "leave_cookies" containers).
I think that there should be a way to configure it separately for every addon. For example FlashStopper or Mozilla Archive Format settings probably should be shared on every container, but it could be good to have option to change it.
One or two others I can think of are NoScript and Ghostery: You do not want amazon to be able to track you everywhere via their for instance, but when you are on the amazon site you need to enable javascript for the site.
Another addon which would work nicely with this feature would be uMatrix. E.g. it would be nice to have a container called "google" where uMatrix allows google.com and related domains to set cookies while within other containers, these domains wouldn't be able to do set cookies. That would be fantastic!
AFAICS, at the moment it's only possible to achieve what I described through multiple profiles which not only need their own windows but also are hard to maintain as you have to install your addons in each profile etc.
Not sure if this is the right place: I'd like to enable work related extensions in the work-container only. And privacy related extensions in my private-container only.
Another use case: enabling VPN or proxy plugin only for specific container.
as far as i understand, multi-account-containers uses the contextual-identity API which neither explicitily does nor doesn't support the separation of configurations of add-ons. that's why a enhancement was requested for firefox.
I use Firefox as my default browser, and for the lack of this feature have been using chrome *shudder* to segment my professional/work usage largely for the ability to create a specific profile which contains all passwords, specific add-ons, etc.
I tried to do the same with FF today, got partly there until adding 1password add-on, which now basically overrides my default firefox logins.
No me gusta 🙄. It would be useful to add container specific permissions to the addons.
Please reconsider working on this feature!
