我如何使用此（或任何其他）資訊來確定哪個加載項導致了此問題？
答案1
我不確定您的特定問題是否屬於這種情況，但在某些情況下，已知的良好擴展已出售給第三方，然後第三方將擴展用於邪惡目的。這是一個討論這個問題的故事：Google Chrome 擴充功能被出售給惡意廣告軟體公司。
摘抄
Ars Technica 的 Ron Amadeo 最近寫道一篇文章關於廣告軟體供應商購買 Chrome 擴充功能以放置惡意的、注入廣告的更新。
Google Chrome 具有自動更新功能，以確保使用者始終執行最新的更新。顯然，Google Chrome 是由 Google 直接更新的。然而，此更新過程因此包括 Chrome 的擴充功能。 Chrome 擴充功能由擴充功能擁有者更新，由使用者決定擴充功能擁有者是否值得信任。
當使用者下載擴充功能時，他們就授予擴充功能擁有者隨時將新程式碼推送到其瀏覽器的權限。
不可避免的事情是廣告軟體供應商從擴展作者那裡購買擴展，從而購買用戶。這些供應商正在向該擴充功能的每個用戶推送廣告軟體，這可能會帶來危險的瀏覽體驗。
一位 Google 擴充作者給了他的個人帳戶他在題為“我賣了一個 Chrome 擴展程序，但這是一個糟糕的決定”的部落格文章中談到了這一點。
我的建議是非常認真地對待這種情況並禁用您不確定的擴充。然後我會監控情況，看看它是否會消退或繼續。
如果這種情況持續下去，我會更深入地研究並開始仔細檢查您正在使用的 DNS 伺服器。我通常使用開放DNS正是出於這個原因，因為此服務（免費）嘗試透過將 DNS 查找重定向到替代 OpenDNS 頁面來阻止攻擊媒介。
為什麼要關心 DNS？
如果已知主機名稱與垃圾郵件/駭客/網路釣魚相關活動有關，則當您進行查找時，OpenDNS DNS 伺服器將有意增加它們返回的結果。他們處於獨特的地位，因為他們對其客戶流量的每個網站執行查找，因此他們可以檢測異常情況，請參閱此處：OPENDNS 網路釣魚防護， 也這裡。
還有什麼？
我還會確保您的/etc/hosts文件沒有受到損害，並繼續使用類似的工具來監視情況nethog，這將顯示哪些進程正在存取您的網路。
Amit Agarwal 在不到一個小時的時間內為 Chrome 創建了一個 Feedly 擴展程序，並在不知不覺中以 4 位數的價格將其賣給了廣告軟體供應商。該擴充功能在發售時在 Chrome 上擁有 30,000 多名用戶。新所有者推送了 Chrome 商店的更新，將廣告軟體和附屬連結注入到用戶的瀏覽體驗中。雖然該擴充功能因 Agarwal 悔恨的懺悔而被公開而被刪除，但這在 Chrome 擴充功能中是非常常見的事件。
答案2
看看擴展的評論流暢的手勢（直接連結）。
如果您按日期對評論進行排序（透過點擊最近的），您將看到幾乎所有新評論都有一星評級，並抱怨不正當的廣告：
凱文李1天前
出售給新增廣告和付費刪除廣告功能的第三方公司。
蘇雷什·納格斯瓦蘭3天前
討厭廣告。效果很好，直到它開始將廣告注入我的瀏覽體驗中。我本來願意付費繼續使用它，但我對這種偷偷摸摸的感覺很強烈。間諜軟體的邊界。
約翰史密斯6 天前
不要使用這個。它透過注入 JS 來點擊劫持，並導致 https 出現 XSS 安全問題。
托馬斯·赫拉瓦切克2014 年 2 月 23 日
絕對是垃圾...還記得未經授權的 URL 偷竊事件嗎？然後他們開始強迫用戶「捐贈」或遭受廣告。它甚至開始在某些頁面上滯後（在所有這些“改進”之前並非如此）。所以我已經改用 CrxMouse，我很好。
凱爾·巴爾2014 年 2 月 19 日
這是一個可靠的滑鼠手勢擴展，但新的廣告是一個可怕的補充。首先，因為擴充功能會更新並默默地添加廣告，所以您不知道它們來自哪裡。在這裡，我使用多個惡意軟體掃描程式掃描我的計算機，因為我收到了隨機廣告，直到我意識到插入它們的是平滑手勢。
沒有充分的理由再使用這個擴展，而且我個人想知道誰開發了這個擴展，這樣我就可以確保將來不會安裝他們的任何東西。
看來罪魁禍首就是那個人。
答案3
除了這裡的答案之外，我還發現了一些更有用的資源。
這個howtogeek文章推薦一個程序叫提琴手充當 Web 偵錯代理，可讓您檢查網路請求（有一個 alphalinux版本）。 @slm 向我指出這個答案SO 上也有各種類似的程序。
chrome頁面中的開發者模式
chrome://extensions可讓您檢查每個擴充功能在背景運行的進程：
點擊 打開
background.htmlchrome 的開發人員工具窗口，您可以輕鬆查看擴充功能包含的各種腳本的原始程式碼。在這種情況下，我注意到support“性感撤消關閉選項卡”的來源樹中有一個名為“性感撤消關閉選項卡”的資料夾，其中包含一個名為“background.js看起來可疑”的腳本（它正在產生適合我的症狀的隨機時間間隔）。這另一個howtogeek文章有一個要避免的已知擴展列表，但更好的是http://www.extensiondefender.com這似乎是用戶生成的惡意擴展資料庫。然而，他們沒有具體說明特定擴充功能如何或為何被標記為惡意軟體或添加軟體，因此也許應該對此持保留態度。
Extensiondefender.com 背後的人（無論他們是誰）還開發了一個非常酷的小擴展，名為（drumroll）擴展防禦者。這既可以讓您掃描現有的擴充功能以查找已知的「不良」擴充程序，也可以阻止安裝列入黑名單的擴充功能。
所以我的OP中的擴展，都是流暢的手勢（感謝@Dennis）和性感撤銷關閉標籤是附加軟體。根據support/background.js後者文件的源代碼，我很確定它是隨機劫持我當前頁面的那個，但我會花幾天時間來確定。
另一個有用的擴充功能是擴展更新通知程序（謝謝@丹尼斯）這顯然會讓你知道每當擴展 haqs 被更新時，這可以幫助識別罪魁禍首，以防更新添加了這種類型的行為。
答案4
一個好的起點是 Chrome 擴充功能「shield for chrome」。它將有助於發現具有已知問題的擴展。它可以在 Chrome Web Store 上找到，免費、精簡且非常易於使用。 https://chrome.google.com/webstore/detail/shield-for-chrome/cbaffjopmgmcijlkoafmgnaiciogpdel
或“擴展後衛”。 https://chrome.google.com/webstore/detail/extension-defender/lkakdehcmmnojcdalpkfgmhphnicaonm?hl=en
