Did you reset Firefox from my above post ?
if that didn't fix the problem, disable Webroot, download free Malwarebytes from https://www.malwarebytes.com/ and run a full scan.
Uninstall Firefox from control panel > programs and features
Install it again if you prefer to use it. otherwise use Chrome or Internet explorer. and check if the problem still persist.
if above didn't fix the problem then you need to Restore Windows to an earlier state when it was okay from a Restore point.
If MBAM doesn't work then you have 2 more options Hitman Pro has proved more efficient in some hard cases of browser Hijack AdwCleaner recently was the only one that managed to delete a nasty hijack i had on one of my client's laptop
