hello GlasEye, this sounds like a problem possibly caused by malware on your pc. please go to firefox > addons > extensions & remove any suspicious entries (toolbars, things that you have not installed intentionally, don't know what purpose they serve, etc). also go to the windows control panel / programs and remove all toolbars or potentially unwanted software from there and run a full scan of your system with the security software that you have in place and different other tools like the free version of malwarebytes & adwcleaner.

Hello ..., I have this problem too. First I have delete in Firefox Start "C:\Users\Juergen\AppData\Local\Mozilla Firefox\firefox.exe" the spam URL after the command. Second I have a further problem with the same URL if I open a new Tab. The spam homepage appears. I have not solved this this problem. Best Regards Jürgen

hey jürgen, my same advice would apply to your situation. basically first look into your extensions and remove all suspicious entries & then run a scan for malware with the tools mentioned.

Great, everty think ok now. Greeting from Dutch www.huyske.com www.glasschitteringen.nl

Hello Philip, thank you very much for your answer. I have installed an Virusscanner at my PC. I have made many scanns and I have found no Virus. I have also scanned my PC with a Spywarescanner, no Spyware was found. If I open a new TAB a Side appears: www.nationzoom.com/newtab/?type=nt&ts=1385837784&from=tugs&uid=ST3500320AS_5QM09MXQXXXX5QM09MXQ I think this side is not reliable. I want that this side disappears from my Firefox. I think my Firefox is modified from a Spyware. I want restore the original state. Best regards Jürgen

in order to restore the original state of firefox, see Refresh Firefox - reset add-ons and settings

Hello Philip, thank you very much for your answer. I have solved my problem. An other friend has my helped. I have set the command "about:config" in the adress Input line. A window has opend and I have searched to the line "browser.newtab.url". In this line was written the bad URL. A right klick at this line with Reset and the bad URL was deleted.

Your Hint with "Reset FireFox" can me help in future for an other problem.

Best regards Jürgen

If you reset, you lose all the add-ons etc I assume?

I too have tried ALL the anti-spam and anti-malware software - and none have detected anything. The problems persist.
