--- Comment #44 from Andrew Church achurch+wine@achurch.org --- I've rebased the ff14-launcher-9.x branch on wine-9.9 and confirmed that it works correctly as modified. wine-9.10 includes changes in dlls/mshtml which conflict with some of these changes and which go deeper than my current knowledge of mshtml allows me to correct for, so I'll have to stop here. (Replacing dlls/{jscript,mshtml} in wine-9.10 with the versions from this branch still gives a working launcher in the resulting 9.10.)
