Sorry I sent in a question but forgot to say that I get Yandex on my screen when I want to open a new tab.

I cannot get rid of it. I believe it is a cookie that is difficult to find, I know it is in my C drive somewhere.

If Firefox deals with Yandex could you let me know as I wont deal with your company.

thank you

See this article about the New Tab page (about:newtab):

Try to reset some preferences to the default with the SearchReset extension:

Note that the SearchReset extension only runs once and then uninstalls automatically, so it won't show on the "Firefox > Add-ons" page (about:addons).


If there is a problem with searching via the default about:home page then try to reset the search engine used on the about:home page.

Reset the browser.startup.homepage_override.mstone pref via the right-click context menu to the default on the about:config page and close and restart Firefox to restore the about:home page to its default.

  1. Open the about:config page via the location bar
  2. Type in the Filter bar: mstone
  3. Right-click the browser.startup.homepage_override.mstone line and select: Reset
  4. Close and restart Firefox

If this didn't help then delete the delete the chromeappsstore.sqlite file in the Firefox Profile Folder and repeat the above.
