有用chrome.css改界面的人要注意一下 这个版有些会失效 我升上去不能用 降版说可能破坏profiles 不给用 害我搞了好久

要降版本Firefox要求你要建立新的设定档时备份Profiles 执行firefox.exe -allow-downgrade或者删除Profiles里面的compatibility.ini刚好v133改了urlbar让很多样式爆炸一些作者已经有提前更新FlexFox 1.0.0目前看起来到明年2月4号的v135都没有问题

我是把compatibility.ini档案里的LastVersion后面的数字改小然后到`about:profile理去重新把他设为default 只是很多台电脑笔电弄很久 请问一下要去哪里才能知道 哪一个版会大改这些东西造成css界面修改不相容啊？ 这次一下浪费好多时间

不要第一时间升上去 让子弹飞一下(误)beta或nightly版本应该会有人讨论?音量图示怎么好像又改了? 听到大家的心声了吗? XD

autohide_sidebar看到讨论才注意到失效，更新了

侧边栏怎样取消，多那条真的很不舒服

晚一点更新确实是好方法XDD

我的TST写好的自动隐藏侧边栏的css也失效了，换成Y大的FlexFox了

所以我都自己写 https://old.reddit.com/r/FirefoxCSS/有变动这里通常都会有人讨论 像最近很哀号特别多然后新的侧边拦可以改sidebar.revamp切换

@bajiqa 斗鱼好像正常了 Orz 莫名其妙就好了！

没有，我开一个直播间放著去看B站，突然卡了，果然连其他分页也全部无法读取，不知斗鱼是是怎么回事

ig、threads跟fb怎么常常要重登 meta在搞? 有人也是如此吗?

IG Threads 我也常常要重登入 FB倒没问题

是这一版之后才这样 现在连google也偶尔发作 其他都没事ˊˋ然后还有跳出fb ig帐号连结windows live帐号的讯息 ˊˋ 会不会是windows defender antivirus搞的鬼?
