Created attachment 364982 [details, diff] firefox-24.2.0.ebuild.diff This is more to show off working firefox-kde integration, but at the same time, firefox-24.2.0 sources appeared. In the end, getting the integration working wasn't as messy as expected. For just the bump, simply remove the KDE bits of the patch. I simply removed the upstreamed patches after unpacking, until there's a new firefox-patches tarball. (diff attached using kfiledialog already) ;)

Ebuild also depends on the not-in-tree-yet kde-misc/kmozillahelper.
Created attachment 364992 [details] snapshot of evidence (note: the shiny non-titlebar firefox window in the background is not what you get from this)
kde patch will not be accepted. It will need to land upstream before we add it to the gentoo patchset, you are more then welcome to keep it in your /etc/portage/patches/www-client/firefox and have epatch_user apply it. Bump will be made on security issue *** This bug has been marked as a duplicate of bug 493850 ***
