User Agent: Mozilla/5.0 (Windows NT 5.1; rv:15.0) Gecko/20100101 Firefox/15.0.1 Build ID: 20120905151427 Steps to reproduce: After downloading Fireworks CS6 from the Adobe Creative Cloud, an add-on window pop up relevant to Fireworks. I accepted the add-on and the issue began. Actual results: Since then, a blue link 'download' appears on the bottom of my home page every time I open Firefox, which takes me to a Web site named Channel 8 News, and right away Norton informs that a threat has been stopped: False Facebook 3. I have uninstalled Firefox and reinstalled it several times, even waited two days before installing it again; however, the link keeps appearing in my Web site. This issue happens only in my home computer.
As I said, the issue does not happen when using Firefox in other computers. And it does not happen when using any other browser than Firefox in the same computer.
Does it happen if you uninstall the add-on you describe yourself as installing?
I have not found the add-on in my programs folder. However, wouldn't a Firefox add-on be uninstalled when Firefox is uninstalled, as well?
Generally, no. Add-ons are installed into the user profile or via the registry, neither of which is uninstalled when the Firefox binary is uninstalled. It would generally not be installed into the Programs folder. You want to go into the addon manager in the Firefox UI (or just type "about:addons" in the url bar) and see what addons are installed.
Hello, Today I installed the Firefox browser in my home computer again, and then checked the add-ons; however, there was no Fireworks add-on. My Firefox home page is my Web site, which again came up with this 'download' link at the bottom that points to my own Web site but it has a '#' sign added at the end of the address. What comes up when clicking the 'download' link is the same Channel8News site, which may be a fake site (I haven't surfed through it), and then Norton tells me that it has stop a dangerous risk. This issue only happens in my home computer and only in Firefox.
That _really_ sounds like some sort of virus infection on your computer, honestly... :(
FYI: Today I disabled all plugins in the Firefox browser, and the link disappeared. When I enabled each of the Shockwave Flash plugins (for some reason I had two), the link came up again in both cases. And then, I changed the home page on the Firefox browser to see what happens with HTML pages: this bug creates links in words that are part of a paragraph in HTML pages that are chosen as home page in Firefox. These links open pop up windows with kind of infomercials in them. What ever this is, it only happens in Firefox in my home computer. Is there anyway I could delete any information relevant to Firefox that stays in my computer after uninstalling Firefox? I would like to try if this fix the issue.
You can try deleting the profile. See http://support.mozilla.org/en-US/kb/profiles-where-firefox-stores-user-data#w_how-do-i-find-my-profile I'm not sure what registry keys are involved. The fact that you have two Flash plugins is _really_ odd, because that should be flat-out impossible. Unless one of them is something completely different and just lying about being Flash...
I finally got rid of the bug that was creating the issue in Firefox in my computer. As you suggested, deleting the profile in my computer was the solution. Thank you for your help.
