Question

I recently bought a second laptop. How can I determine which add-ons I currently have installed on my first computer?

Answer 1

You can look in Firefox Button > Add-ons
You can add the following extension to list them for you. Adds a button in Firefox 4 Add-ons window/tab "Dump List". Click that button, window opens, if you just want extension names and version only, un-check everything except version, then save the list to a file by clicking save at the bottom of the window it opens or highlight the list, then Ctrl+C to copy, open Notepad, Wordpad or another application (Word), and paste, then save if you wish:
*'''''Extension List Dumper''''': https://addons.mozilla.org/en-US/firefox/addon/extension-list-dumper/
<br />
<br />
'''You need to update the following (all of your versions have known security issues):'''
