Hello ryzies,
To avoid confusion, I have merged your most recent topic, "Can't Start Firefox" in this forum to your previously existing topic. Starting 2 topics about the same problem is called double posting and is not allowed on this board.
Please keep all of your replies concerning this issue to this topic.
The members helping you will be looking for your responses to their questions in the topic they replied to.
Posting it elsewhere, will cause a delay in the help you receive, and neither one of us wants that.
Let us know if you have any success with Joshuacat's suggestion.
Please note it is possible the problems with installing Firefox may be related to your infection. If Joshuacat's idea doesn't work, please wait until your system is declared clean and then try to install Firefox.
