It doesn't update actively running application containers.

You don't actually need to stop it before running “snap refresh” though, it'll just be out of date as long as it is kept open. Once the application stops running, next time it is run the updated image will be used.

[caveat: I'm not a snap user myself currently, so my information may be inaccurate, take with a pinch of your favourite condiment]

Interesting. On Arch, Firefox just refuses to keep working after I've updated and requests me to restart it.

That is Firefox standalone behavior when it detects its files have been changed and differ from the ones loaded by the current instance. In theory, what snap is doing avoid changing files from a program while it is running.

Yeah, that makes sense.

Now, I don't know how your setup looks like, but I don't think anything is distributed as snaps by default on Arch. At least AFAIK its mostly an Ubuntu & derivatives thing.

Well, it was more broken in more interesting ways before they implemented the forced restart

[guerrilla]

Yeah, I remember. That was fun. haha
