升级firefox到3.0之后，为什么···

三翻领

不是的，这个和xulrunner一点关系也没有。
元凶是mplayerplug-in，它只能和ff2系列一起工作。
楼主如果想验证，可以在package.mask里面mask掉小于等于2.0.0.14的ff，然后emerge -pvuDN world，会出现：

1. !!! All ebuilds that could satisfy "=www-client/mozilla-firefox-2*" have been masked.
2. !!! One of the following masked packages is required to complete your request:
3. - www-client/mozilla-firefox-2.0.0.14 (masked by: package.mask)
4. /etc/portage/package.mask:
5. #<sys-libs/glibc-2.5
6. #>app-emulation/wine-0.9.55
7. #>net-fs/samba-3.0.27a
9. - www-client/mozilla-firefox-2.0.0.11 (masked by: package.mask)
11. For more information, see the MASKED PACKAGES section in the emerge
12. man page or refer to the Gentoo Handbook.
13. (dependency required by "net-www/mplayerplug-in-3.50" [ebuild])

复制代码

因此，删掉mplayerplug-in后，依赖关系就顺了。

net-www/mplayerplug-in-3.50启用xulrunner就会依赖=net-libs/xulrunner-1.8*，不再依赖=www-client/mozilla-firefox-2* 了。

那看来是我错了

net-www/mplayerplug-in-3.50 以前是没有 xulrunner 这个 use 的。你应该没错，呵呵。

Fix xulrunner depends, bug #217160

都是最近改的，为了支持 Firefox 3……

那再改，我没错，哈哈

汇总一下USE为firefox和xulrunner的各自依赖：

1. ~ $ equery d mozilla-firefox
   
2. [ Searching for packages depending on mozilla-firefox... ]
   
3. dev-java/swt-3.4_pre6-r1 (firefox & !xulrunner? =www-client/mozilla-firefox-2*)
   
4. dev-python/gnome-python-extras-2.19.1-r1 (!xulrunner & firefox? =www-client/mozilla-firefox-2*)
   
5. gnome-extra/yelp-2.22.1-r1 (!xulrunner? =www-client/mozilla-firefox-2*)
   
6. media-video/totem-2.22.2-r1 (nsplugin & !xulrunner & !seamonkey? =www-client/mozilla-firefox-2*)
   
7. net-www/mplayerplug-in-3.50 (!xulrunner & firefox? =www-client/mozilla-firefox-2*)

复制代码

1. ~ $ equery d xulrunner
   
2. [ Searching for packages depending on xulrunner... ]
   
3. dev-java/swt-3.4_pre6-r1 (xulrunner? net-libs/xulrunner:1.8)
   
4. dev-python/gnome-python-extras-2.19.1-r1 (xulrunner? =net-libs/xulrunner-1.8*)
   
5. gnome-extra/yelp-2.22.1-r1 (xulrunner? =net-libs/xulrunner-1.8*)
   
6. media-video/totem-2.22.2-r1 (nsplugin & xulrunner? =net-libs/xulrunner-1.8*)
   
7. net-www/mplayerplug-in-3.50 (xulrunner? =net-libs/xulrunner-1.8*)
   
8. www-client/epiphany-2.22.2-r10 (=net-libs/xulrunner-1.9*)

用xulrunner替换firefox确实可行！不过xulrunner会出现两个slot并存，为了个firefox…………2变成3…………显然不划算。观望……

亞利艾爾

按版主说法就是 SLOT 就是拿来并存的……

怪不得安装firefox3后，还要安装2。
