I had the same problem. en-US is the default GNOME language, the default returned by "locale", and even the "preferred language for displaying pages." But the en-GB dictionary was the spell-checking default.
This is easily fixed in the preference settings (right-click in a textbox, choose a setting from "Languages"), but a little strange. Also, the fix is not immediately obvious, because language settings are displayed in many separate parts of the Firefox UI. For example, there is no en-US module listed in the "Add-Ons -> Languages" tab, so I thought I might have to go download one at first, but it turns out this panel is not really relevant to the question at hand---it's not an exhaustive list of installed language modules, only of "add-on" modules (whatever that means). It seems also that the dictionary setting is *only* available via a right-click in a textbox, and not through the Preferences UI. This is hardly intuitive. I realize these UI infelicities aren't properly reported here. I mention them as support for the notion that the firefox package ought to set the right defaults---fixing the setting can be confusing. -- Firefox spellchecker is not honoring the native language support specified in the Firefox configuration https://bugs.launchpad.net/bugs/320266 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
