Comment # 2 on bug 1227486 from Fabian Vogt

kmozillahelper provides dialogs for open+save file selection and some other
miscellaneous integration. It is legacy and meant to be dropped as soon as
possible, it's just waiting for Firefox:

> I noticed this when clicking URLs where often they won't even reach firefox because kmozillahelper already looked them up.

I cannot follow there - kmozillahelper does nothing on its own, it's started
and managed by firefox and only does whatever FF tells it to. I'm not aware of
any command that causes kmozillahelper to receive an URL and "look it up".
