I'm debugging a web application that doesn't work for a user and one of my suspicions is that an installed Chrome extension is interfering with it. Is there an easy way for the user to provide me with a list of their installed extensions? chrome://extensions is a possibility, but it's not easy to extract the information I need except to copy each name manually.

    he can select everything on the page with CTRL+A and copy it to Word / Excel / e-mail application ... and send it to you. – Máté Juhász Jan 6 '17 at 13:31
  • @MátéJuhász, you can't use CTRL+A on this page. – Black Aug 6 '18 at 13:59

Go to chrome://system and click the expand button to the right of the "extensions" row. This provides a comma sorted list of all extensions. You can drag and highlight the list to copy.

This also has the benefit in that it lists on active extensions since installed but deactivated extensions can be ruled out. For a complete list have them activate all extensions they have, refresh the chrome://system page and copy the now updated list.

  • When you copy the list it will have entries such as aapbdbdomjkkjkaonfhkkikfgjllcleb : Google Translate : version 2_0_6. To remove the first part, you can use Notepad++, Search and Replace (enable Regex), enter at "Find what:" ^([^:]+:)(.) and "Replace with:" \2. Then you get Google Translate : version 2_0_6.

  • +1 Lifesaver! This so worked well. ... But, why/how can't I scrape the info with querySelectorAll? I mean technology-wise ... what is the technique or program that is preventing it? – Eric Hepperle - CodeSlayer2010 May 3 '18 at 20:53

Is there an easy way for the user to provide me with a list of installed extensions?

You can use BrowserAddonsView from Nirsoft:

BrowserAddonsView is a simple tool that displays the details of all Web browser addons/plugins installed in your system. BrowserAddonsView can scan and detect the addons of most popular Web browsers: Chrome, Firefox, and Internet Explorer. For Chrome and Firefox, BrowserAddonsView detects and scans all Web browser profiles if there are multiple profiles.

Your can sort the output by "Web Browser" and then select the Chrome extensions.

enter image description here

Then either:

  1. "File" > "Save Selected Items" to export to a text file, or

  2. "View" > "HTML Report - Selected Items"

Here is an extract from the text file for my Chrome:

    Installing additional software isn't exactly the easiest route – Gremlin Jan 9 '17 at 10:28

    IMO this is both the easiest and the best route. Aside from the simple (portable) installation of this small freeware program, one need only select the most important columns (e.g. Name, Status, Web Browser, Version, Description), then Save As (I like the CSV format best because it can open in any spreadsheet/etc and then be pasted into any text document. Has the benefits of working with multiple browsers, showing which are active/disabled, and other items like dates, sizes, folders etc. if needed. Truly elegant and comprehensive solution which should be utilized. – chronometric May 29 '17 at 0:57

    Nirsoft is also Windows only. Doesn't help Mac users. – RHPT Nov 12 '17 at 3:22
  • Note: It can open any Chrome profile folder via Options -> Advanced Options. It doesn't have to be installed on the computer that has the browser installation. So if you have access to a Windows computer (or virtual machine), you can copy the relevant profile folder(s) over and view the extensions in it. – user1151080 Apr 4 at 5:52
