Thanks for your report. This sounds not as a bug to me, but rather a support request.
As regards the first issue, please go to Settings -> Region & Language, click the cog wheel to the right of the Input Sources label, and make sure that "Use the same source for all windows" is selected. Since you have a Japanese keyboard, I think it may work smoother is you open the file /usr/share/ibus/component/mozc.xml for editing and replace <layout>default</layout> with <layout>jp</layout> Pls let us know if that helps. ** Changed in: mozc (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1973847 Title: Sometimes Firefox could not change mode from English to Japanese To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mozc/+bug/1973847/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
