Firefox 48 啟動後不到一分鐘就崩潰了。即使沒有任何用戶輸入，它也會崩潰。它正在向 Mozilla 發送自己的崩潰報告，而 Ubuntu 沒有收到崩潰訊息。
從命令列啟動 Firefox，輸出如下：
$ firefox

關於如何解決這個問題有任何提示嗎？
更新一：在安全模式下執行 Firefox 沒有任何改變，它仍然在啟動幾分鐘後崩潰。使用該--debug標誌只會彈出 gdb 提示符號：

更新二：我已使用訪客使用者登入並在該會話中嘗試使用 Firefox。那裡也經常發生崩潰。
答案1
訊息：
sdk/widget在資源://gre/modules/commonjs/sdk/widget.js 處找不到模組
意味著您有一個不適合此版本的 Firefox 的插件或插件。上面那條線...
console.error: irc-client:
指向插件或插件。該軟體中有一個require("sdk/widget");或類似的東西，並且模組“小部件”不存在。
請參閱這篇 MDN 文章：「小部件」在 FF38 中被刪除並且這是現在應該的樣子: require("sdk/ui");。
- 可能的修復：清除（因此所有插件也被刪除）ff 48 並從系統中安裝 49。我的就像一個魅力。

如果您最終出現 gdb 提示符，請輸入跑步然後按回車，程式就會運行，到了某個時候會崩潰，然後就可以運行了BT獲得回溯。這就是使用 gdb 進行調試的基礎知識。
