  mozilla-nss     openSUSE -> obs://build.opensuse.org/mozilla


3 packages to upgrade, 2 new, 2 to remove, 3  to change vendor.
Overall download size: 67.5 MiB. Already cached: 0 B. After the operation, additional
23.1 MiB will be used.
Continue? [y/n/...? shows all options] (y)

why removing two apps “java-1_8_0-openjdk-headless-1.8.0.121-3.3.x86_64” and “java-1_8_0-openjdk-1.8.0.121-3.3.x86_64”?
Thanks

This is not an update, but an installation of a specific version. And it even needs a vendor change.

Where (which repo) should that version come from? Apparently from another repo then the one you used until now.

If choose 3 (Solution 3: break MozillaFirefox-53.0-6.8.x86_64 by ignoring some of its dependencies) Whether it will be successfully installed? or Or should I choose option 1 to install

That is NOT an answer to my questions.

I want to installing Firefox 53 in the repo Mozilla
but show error post 1

I mentioned in my first post
repo mozilla

Hi
Latest is not the greatest… See https://lists.opensuse.org/opensuse-factory/2017-04/msg00925.html on the current status and move to ESR version.
