『推荐』备份你的Firefox：Firefox Extension Backup Extension …

FEBE(Firefox Extension Backup Extension ) allows you to quickly and easily backup your Firefox extensions.  In fact, it goes beyond just backing up -- It will actually rebuild your extensions individually into installable .xpi files.  Now you can easily synchronize your office and home browsers.

FEBE  备份你的扩展、主题、和（可选）书签、preferences、cookies。

CLED(Compact Library Extension Organizer)is a Firefox extension that works with FEBE to package any number of extensions/themes into a single, installable .xpi file.

You may have a list of your favorite extensions/themes that you would like to share with others.  With CLEO, you can gather them all together into a single file (called, perhaps, "My favorite extensions.xpi") and post them on a webpage.  Others can install the whole batch with a just a couple of clicks!

效果如果？原来也有过这样的软件如mozbackup

最安全就是手动备份。
