Mozilla Firefox 45.0.1 今晨发布，作为一个修正版，主要修复了一些45版本正式发布后使用上出现的问题，例如搜索引擎和地址栏设置丢失的问题，并没有增加新的功能，45版用户可以通过软件内的升级功能自行升级，也可以直接从FTP下载安装包。
Version 45.0.2, first offered to Release channel users on April 11, 2016
We'd also like to extend a special thank you to all of the new Mozillians who contributed to this release of Firefox!
