Re: i cant stop firefox opening an unwanted window on startup

please try uninstalling firefox from the windows control panel & chose to remove all personal data. afterwards manually check if the firefox program folder got deleted (it's usually in C:\Program Files\Mozilla Firefox) and else remove it manually. then download & install a fresh copy at getfirefox.com

it should show a "welcome-page" after the first run. if not, please also reset firefox...

Re: i cant stop firefox opening an unwanted window on startup

I will post further suggestions later first of all

  1. have you actually found and quarantined/deleted any malware
    (and if so do you recall what that was)
  2. try this restartless add-on it may solve the problem for you
  3. see also Remove a toolbar that has taken over your Firefox search or home page

Try the add-on, it should reset the homepage. Post back with how you get on, if for instance the homepage resets but later reverts to something you do not like you may still have a bad file that we can remove to stop that happening.

Re: i cant stop firefox opening an unwanted window on startup

hi further to explanation .. it opens all my past pages including home page in one window .. as i have it usually set to ... this is another window which shows as a new window on the task bar and appears as a short black strip with a few of the words that are on the address . which also changes occasionally at the top of the screen ... the full address is taken from what shows as the second window on the task bar i have tried forget history , only open home page and open a blank tab .. all still launch this unwanted window .. my browser is set to open all new pages in a new tab not a new window .. none of the malware or virus programs have detected any malware or virus and i dont normally run high speed centrifuges or have a lot of uranium onhand

Hi Phill,
Sorry you are still having problems.

Did you try the searchreset add-on I mentioned. The link to the download page is https://addons.mozilla.org/en-US/firefox/addon/searchreset/

Maybe it helps if you provide a screenshot

Hi phill_nz

try first install Adblock Plus add-on and then install Adblock Plus Pop-up Addon

(Adblock Plus is required to work the Adblock Plus Pop-up Addon. If you install only the pop-up addon will see a message saying additional items required it means that you don't have Adblock Plus installed)


thank you

i have always used both of them and they are active .. as this also happens after i have done an uninstall and reinstall and an uninstall and an upgrade .. i need to be able to find / destroy firefox hidden memories .. that might work

Re: i cant stop firefox opening an unwanted window on startup

I know exactly what you are talking about, I have the same issue. Tried Uninstalling Firefox but when I reinstalled fresh version and dropped my profile in it the same thing happend still. The little ad that pops up in its own window when I launch Firefox!!!!! However I remember exactly when it started... Did any of you guys install some moon phase Firefox extension or plugin at some stage? Dont know if it was SunCult but when I launched it the first time it asked [ if I will allow this ad because the software is worth it ] I wanted to see it work so I said ok thinking I can always remove it afterwards if not cool. That was my mistake and Ive been living with the same problem you have ever since!! Does this ring any bells phill_nz?? Let me know
