I set yahoo as my home page but mozilla opens with http://istart.webssearches.com as home page

My home page is set to yahoo but I think due to installation of some software the home page was changed to http://istart.webssearches.com. I again changed home page to yahoo but still mozilla opened http://istart.webssearches.com this link as my home page. Even resetting Mozilla didn't solve the problem. Is there something to do in about:config? Kindly help me out.

hello, this sounds like a problem possibly caused by adware on your pc.

please go to the firefox menu ≡ > 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.
finally, run a full scan of your system with different security tools like the free version of malwarebytes & adwcleaner.
