Suddenly after installing and uninstalling some toolbars, search engines are gone from firefox.
If I go to manage search engines I see nothing.
If I click Get more search engines I got nothing.
The search bar doesn't work. I can type google.com, etc. and it does nothing.
Some says I got to remove search.json from my firefox profile

It doesn't work. It isn't created.
Reinstalling firefox doesn't help.
Only happen in one user in my computer.
