Firefox keeps becoming corrupted

Posted

I have three web browsers on my MAC Book Pro, and only Firefox is becoming corrupted. A week after installation I'll find that google.com no longer is my homepage (even though I've indicated it in preferences.) What appears to be another browser (centurylink.com) will appear listing hits like it does on google. I've gone to Century Link and deselected all if its services so that this doesn't happen - but it continues to happen. I uninstalled Firefox because Century Link said it was corrupted, and reinstalled it, and the same thing happened again after a week. I don't know why this is happening. Right now, I have Firefox uninstalled because I think it's a security risk. None of this is happening on the other browsers, by the way: Safari, Google Chrome.

Thank you for responding to this!
