Hi there, I just made a mistake that I would like to correct, but I am not sure how to do it. I installed an activex extension called "mozactivex-ff-15.xpi" that came from Yahoo.com in order to be able to play video from that site. But I did so thinking that I would be able to disable the extension as soon as I was finished watching the video that I wanted to see. But a) the extension does not show up in the Extensions window, and b) trying to open the video crashed FF and I had to restart it. So how can I undo my mistake and completely remove this ActiveX control? The install log reads like this: ***************** ActiveX Plugin (version 18.104.22.168) -------------- ** File found: msvcrt.dll ** File found: msvcp60.dll ** File found: msvcp70.dll [1/4] Installing: C:\Program Files\Mozilla Firefox\plugins\npmozax.dll [2/4] Installing: C:\Program Files\Mozilla Firefox\components\nsIMozAxPlugin.xpt [3/4] Installing: C:\Program Files\Mozilla Firefox\components\nsAxSecurityPolicy.js [4/4] Installing: C:\Program Files\Mozilla Firefox\defaults\pref\activex.js Install completed successfully ***************** How do I reverse what I have done? I have a feeling that I can't simply delete the .dll without unregistering it first, but I don't know how to do that. Thanks.
