AFAIR many years ago (in firefox 1.x days) Pango was already the cause of many people's slowdowns, it was also slower the more fonts you had installed on your system. Back then, you could disable Pango at runtime by doing: export MOZ_DISABLE_PANGO=1 Maybe it still works.

Unfortunately by now I have already forgotten why I was even removing pango in the first place, so I think I'll re-enable it. Pango is used for rendering non-Latin characters, e.g. Japanese and Chinese glyphs. It does slow things down somewhat and it's not necessary if you're only using Latin-type characters (i.e. US, Canada, and western Europe). At one time, there was a moznopango USE flag, but that seems to have disappeared. -- Walter Dnes waltd...@waltdnes.org

I think I'll try building manually and see what happens. Sorry, I went after the wrong eclass. Apparently www-client/firefox compiles just a shell of an application (front-end, mostly written in XUL and JS?) when the real stuff is in net-libs/xulrunner. And xulrunner's ebuilds use mozconfig-3.eclass instead. Another thing I noticed about mozilla's build system is that one *must* remove the enabling from the eclass(es) due to the way mozilla's configure checks for these settings. If you have both --enable-pango and --disable-pango in .mozconfig then enable will override. And since Gentoo moz* eclasses will automatically force several enabling lines into .mozconfig, it's useless to add --disable-foo later on (e.g., in the ebuild). The change has to be made in the eclass(es).

If you referring to a USE flag, I don't see it anywhere. Must be obsolete.
OK, I'll have to modify that. Wonder why the Gentoo ebuild maintainer
dropped it.

--enable-oji
Open JVM Integration: it enables support for the java plugin named
libjavaplugin_oji.so
Since I don't bother with Java, I may as well disable this.
