Whenever i visit a webpage, the browser will forward any link to "http://www.purchasereviews.net/donate.php" instead of the link specified in the pagesource!
Since a week, the browser will forward me to "http://www.purchasereviews.net/donate.php" whenever i click on a link to another page. The page source however direct to the original intended address. The address specified link above will show up in the status bar at the bottom of the browser. Uninstalling / re-installing the browser or any other older version of firefox doesn't seem to help. Safari has no problems when visiting the same pages, and neither the virus or malware scanner pick it up.

There are postings in several forums on the internet that this is caused by the add-on Youtube MP3 Downloader 2.1 which you have installed and is included in the list of extensions provided with your original question. In addition, there are comments on the add-on page for Youtube MP3 Downloader version 2.0 in the "Reviews" section (link - https://addons.mozilla.org/en-US/firefox/addon/youtube-mp3-downloader/ ). Note that version 2.1 of that add-on is NOT available on the Mozilla add-ons site. It is pointed out in several posts in various forums that you must REMOVE the add-on not just disable it. Remove the add-on and see if that solves your problem.
