I'm sorry about the issue. Please try the following fix:
- Click on the 3-bar icon at the upper right corner in Firefox program, then click on Options
, then at the box on the right of the option Home Page, delete everything in it, then type yahoo.com
, then click on the option Search on the left, then click on the drop-down list at the top, then click on Yahoo
, then it should work.
Please reply at the box below to continue troubleshooting. Thank you.
