video capture add-on problem

more options

Background: hardware- newly built computer- Celeron D 3.33GHz, Windows 7 64 bit (legal purchase)

  software: Mozilla Firefox 27.0.1 downloaded from Mozilla, installer file=Firefox Setup Stub 27.0.1

Problem: Firefox operates fine until I install a video capture add-on like Easy Youtube Video Downloader or Youtube and More-Easy Video Downloader from the Mozilla site.

Once one of these are installed I get lots of windows popping open everytime I go near a site with videos. One window's URL started with jsf.jsticket.net..... and asks to download some software. Multiple windows have opened with all sort of software download/install links.

I have uninstalled Firefox using RevoUninstaller and tried installing again using a freshly downloaded Firefox installer. When I put in one of these add-ons things go bad again.

I have run a security sweep in Safe Mode-proceedure outlined at http://securitytango.com/windows.php software run in Safe Mode not attached to internet: Rkill Unhide TDSSKiller Stinger SuperAntiSpyware (update it first) Malwarebytes' Anti-Malware (update it first) antivirus program (update it first) There was now virus or malware detected.

I'm going a bit crazy because I have another machine running with Windows 7 & Firefox 27.0.1 with Youtube and More-Easy Video Downloader 1.97.25 and it works just fine.

Can anyone suggest a solution to this problem. Any help will be greatly appreciated. Dave

We can't check if you have any malicious extensions without a list (this information is normally provided by the Troubleshooter add-on, which you declined to install).

  1. Type about:support into the address bar and press Enter.
  2. Copy the entire Extensions category to the clipboard.
  3. Paste the clipboard contents into a reply here.

Are you referring to the following two add-ons from the Firefox Add-ons site? They've both been fully reviewed and have user bases numbering in the hundreds of thousands. The odds of either containing malware should be slim to none.

There are no Extensions listed in that part of the report as I have done another clean installation. I'm tempted to put in an add-on but I'm holding off on installing any video capture extensions/add-ons because I don't want to go through having to remove and reinstall if I run into a problem again. Like I noted I tried a couple different add-ons and even put in a popup/ad killer and I still had all sorts of garbage windows opening up.

I'd like to know if there is one add-on that really works. SoThink used to be what I used but it seems to have not kept up with the Firefox new versions. Others listed on the Mozilla site have had complaints registered lately about not working. Again any help will be appreciated. Dave

I've tested Download YouTube Videos as MP4 multiple times in the past and again just now. I had no issues with it.

The built-in pop-up blocker and add-ons like Adblock Plus cannot prevent ads opened or injected by malware. The only solution is to remove the malware. Even if the computer itself is clean, you may have malware in your router. If the problems persist, I suggest you refer to a forum specializing in malware removal and have someone there analyze your logs.
