'addon' and 'onboard' are being shown as spelling errors as I type this. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/894085 Title: On newly installed Firefox, spell checking is enabled but no language is selected To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/894085/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
