The tabs and the buttons in the upper left (red, yellow, green on Mac) no longer overlayed properly. -Home page was redirected to 124bytes.com (the 124 bytes part is correct, not sure if this is the whole address -Surfed to google.com who notified me that I was using an old version of Chrome -Shut down all add-ons, restarted browser, returned to Google.com, same notification (wanted to ensure that it wasn't an add-on malfunction) -Changing home page would stick until the browser was restarted -Ran virus/malware scans: Malwarebytes, ClamXav -No issues were returned with either Resolution efforts (in order): -ClamXav virus scan -Malwarebytes scan -Delete and reinstall Firefox -Use terminal to look for hidden directories (none found) -Removed (rm -r) all Mozilla and Firefox directories from /Library The last effort seems to have resolved the problem.
