Today's release brings innovative functionality, improvements to core browser
performance, and more proof that we’re committed to making Firefox better
than ever. New features include support for WebVR, making Firefox the first
Windows desktop browser to support VR experiences. Performance changes
include significantly faster startup times when restoring lots of tabs and
settings that let users take greater control of our new multi-process
architecture. We’ve also upgraded the address bar to make finding what you
want easier, with search suggestions and the integration of our one-click
search feature, and safer, by prioritizing the secure - https - version of
sites when possible. Read what Nick Nguyen (VP, Firefox Product) has to say
about Firefox 55, get historical perspective on the development of WebVR from

还是退回到54.0.1了，刚刚试了55、56、57，右上角的X钮没用，无法关闭，只能进装置管理员；Tab-Mix的Session manager也没用，按下无法回复上次开启的分页，超不方便。

锁定分页没作 用

lawlietfox还真的比官方版还稳定的说

回楼上 → 装开发版就可以了~

所以是 内建https everywhere?

不知道放进推送频道了没，之前55.0/55.1的时候我的54.1版按关于fx都说最新的

直接抓M社FTP的安装档来安装最好，不会有这种问题

这次真的很迷 一周了没推送 虽然有马上释出小修正版可能是因为这版开始标记那些套件是传统的所以官方不主动

noscript今天是不是怪怪的? 原本设定好的网页今天全回复到默认状态 导致现在开网页都要重新设定

不清楚 前两个更新都自动的 今天的是我手机版有更新 所以自己按更新的

有人知道pcx是怎么了都没更新耶，还停在53

pcx多久才更新一次 谁敢用阿......我还不如拿tete的来用

55.0跟55.1都没推送，55.2就推了＠＠..

上次看到PCX说要顾小孩..应该是很忙才没更新的

不如用lawlietfox PCX的更新速度...

旧版附加元件就有显示问题了，现在55.02还给我全关光我都不知道要去找新欢还是等旧爱了

感觉还是继续用54似乎比较好些

要停留的话52ESR比较好 只少半年内可收到安全性更新至

现在有tmemutil.dll功能的还是只有pcx和tete吗 t有x64了吗
