我之前有閃過一次 後來就沒有了
你要不要重建配置試試看？？？ :agree:

在excel online 按右鍵時firefox選單會擋到excle的選單
youtube也會
本以爲是某插件影響，結果全插件移除還是一樣

原因是什麼？

重建配置也碰到那種閃退狀況
連移除重新安裝也無解

後來選項設定裡關閉硬體加速那個功能，目前暫時沒再發生

先觀察看看

更新到58後目前用兩天是還OK，沒遇到多大問題

但是這兩天一直覺的桌面怪怪的

剛剛才發現.......更新後會把原來icon下Mozilla Firefox改成Firefox

難怪覺得少了什麼 :stupefy:

Firefox 59 將引入一系列新 WebExtensions API

Firefox 57 淘汰了舊的擴展，正式轉向了 WebExtensions 擴展架構，但目前 WebExtensions 提供的功能相比舊擴展架構要少許多，導致很多流行的擴展難以移植到新架構。Mozilla 官方博客宣佈下一個版本 Firefox 59 將會引入一系列新的 WebExtensions API 和改進，包括：標籤隱藏，browserSettings.openBookmarksInNewTabs() API，browserSettings.openSearchResultsInNewTabs() API，tabs.captureTab()，更多主題 API，改進 webRequest API，改進 browserAction 和 pageAction，增強擴展對 cookies 的控制，改進代理設置， 等等。此外 Firefox 59 還將支持去中心化協議 Dat Project (dat://)，IPFS (dweb:// ipfs:// ipns://)，Secure Scuttlebutt (ssb://)。

高手有事做 56可以亡了？？？∼∼:D :D :D :D :D

看來等Firefox更新到6字頭後，再來進行版本升級評估好了 :shy:

既然如此那就可以跳過57跟58不看
等59出來再來看看套件究竟有沒有更新再說

Tab Mix WebExtension (experimental)

https://addons.mozilla.org/en-US/fi...s-webextension/

+1，沒有easy drag to go跟tab mix，根本就不是firefox
