This did not help solve the problem.

-> Restore the default home page

-> OR Set a single web site as your home page

IF its working on these homepages, then ask about this problem from the Comcast Techincal Support.

Still does not work.

Does it work when you use some other website as your homepage ??

Yes, the google search works on other homepages.

Then as i mentioned in one of previous reply, ask about this problem from the Comcast Techincal Support. They will know what's changed on their website.

OR for further testing, Create a New Profile as a test to check if your current profile is causing the problems.

-> Basic Troubleshooting - Make a New Profile

-> Set Comcast's website as your homepage in the New Profile.

IF that New Profile works then you can recover your Bookmarks and Passwords from the Old Profile.

Check and tell if its working.
