The whole idea behind Manjero’s update scheme is just generally a landmine. LTS releases typically work by maintaining a older branch that gets updates. In this way you delay features not patches. If you run Firefox on such a system it will be Firefox LTS with this week’s patches (this is kinda important for security reasons). Manjaro doesn’t do this instead it just holds everything back artificially one or two weeks.

Bluntly doing this with a browser or other security critical software should be a crime.

Manjero just generally feels very amaturish and its history of taking down Arch’s servers is not helping here.
