有用chrome.css改界面的人要注意一下 這個版有些會失效 我升上去不能用 降版說可能破壞profiles 不給用 害我搞了好久

要降版本Firefox要求你要建立新的設定檔時備份Profiles 執行firefox.exe -allow-downgrade或者刪除Profiles裡面的compatibility.ini剛好v133改了urlbar讓很多樣式爆炸一些作者已經有提前更新FlexFox 1.0.0目前看起來到明年2月4號的v135都沒有問題

我是把compatibility.ini檔案裡的LastVersion後面的數字改小然後到`about:profile理去重新把他設為default 只是很多台電腦筆電弄很久 請問一下要去哪裡才能知道 哪一個版會大改這些東西造成css界面修改不相容啊？ 這次一下浪費好多時間

不要第一時間升上去 讓子彈飛一下(誤)beta或nightly版本應該會有人討論?音量圖示怎麼好像又改了? 聽到大家的心聲了嗎? XD

autohide_sidebar看到討論才注意到失效，更新了

側邊欄怎樣取消，多那條真的很不舒服

晚一點更新確實是好方法XDD

我的TST寫好的自動隱藏側邊欄的css也失效了，換成Y大的FlexFox了

所以我都自己寫 https://old.reddit.com/r/FirefoxCSS/有變動這裡通常都會有人討論 像最近很哀號特別多然後新的側邊攔可以改sidebar.revamp切換

@bajiqa 斗魚好像正常了 Orz 莫名其妙就好了！

沒有，我開一個直播間放著去看B站，突然卡了，果然連其他分頁也全部無法讀取，不知斗魚是是怎麼回事

ig、threads跟fb怎麼常常要重登 meta在搞? 有人也是如此嗎?

IG Threads 我也常常要重登入 FB倒沒問題

是這一版之後才這樣 現在連google也偶爾發作 其他都沒事ˊˋ然後還有跳出fb ig帳號連結windows live帳號的訊息 ˊˋ 會不會是windows defender antivirus搞的鬼?
