[Solved] No more notifications in v3 with firefox

I use mattermost at home on linux with direct access and at work on windows behind a proxy.
in v2.1.0, I had desktop notifications with the 2 configurations but since I upgraded mattermost to v3.0.2, I don’t have them anymore.

Did something change between the two versions regarding notifications?

Thanks!

With a fresh firefox profile, notifications work properly.

Sorry for the noise
