firefox-38.6 套件實例

緣由：firefox v38.0.1 某些網頁會當掉。
v38.6 有 firefox hello 視訊 (video+audio)，但沒有文字聊天室。

[dywang@dywnb ~]$ cd rpmbuild
[dywang@dywnb rpmbuild]$ wget ftp://ftp.pbone.net/mirror/ftp.redhat.com/pub\
/redhat/linux/enterprise/6Workstation/en/os/SRPMS/firefox-38.6.1-1.el6_7.src.rpm

安裝 SRPM 套件

[dywang@dywnb rpmbuild]$ rpm -ivh firefox-38.6.1-1.el6_7.src.rpm

解壓縮原始碼 tarball，產生 mozilla-esr38 目錄，存放原始碼。
```
[dywang@dywnb SOURCES]$ tar jxvf firefox-38.6.1esr.source.tar.bz2
```

建立 RPM 二進位檔，出現相依套件問題，不同的建立環境缺的套件不會相同，必須把缺的套件都安裝起來。

安裝 firefox 開發相依套件。

再同時建立 RPM 及 SRPM 二進位檔字，還需要 libc.so.6 及 libc.so 函式，經查為 glibc.i686 套件提供，再安裝此套件。

再同時建立 RPM 及 SRPM 二進位檔字，firefox RPM 建立要 1 小時以上，要耐心等候。成功建立的訊息最後幾行，看到產生 firefox firefox-debuginfo 二個 RPM 檔及一個 firefox SRPM 檔。

更新 nss-* 套件，解決上述問題。還是無法解決，關閉所有分頁瀏覽，重新開啟網頁，暫時不崩潰。
```
